Chapter 4
OPERATION
The DMP-160 Series plotters are opeated through the control panel with its 32-character adjustable contrast LCD and 12 control keys. Features and options of the series available through the panel are:Control Panel
- Selectable plotting languages: DM/PL, and HP/GL and HP/GL2 emulation.
- Selectable plot code sorting, plotting speeds and accelerations.
- Selectable English or metric menu operation.
- Windows and scaling capabilities to manipulate the size and location of a plot.
- Multiple text character sets and DM/PL font styles.
Operation of the plotter is accomplished through the LCD and control panel keys, as discussed in the following paragraphs.Liquid Crystal Display (LCD)
The LCD of the DMP-160 Series plotter is organized into two rows of 16 characters each. The display intensity is adjustable.Online Key
The Online key toggles the plotter between on-line and off-line operation. The mode is displayed with each key press.Selected/Deselected Message
The plotter is initally in the on-line mode at power-on. In the on-line mode, plotting operations are enabled. When media is loaded in the plotter and the plotter has been selected (see below), an on-line plotter begins executing plotting commands from the input buffer as soon as they are received from the host computer.
In the off-line mode, the plotter can still receive data into its input buffer if it has been selected, but plotting operations do not begin until the plotter is switched on-line. The plotter can be operated manually in the off-line mode using the following control panel keys:
- Pressing the left or right arrow key moves the pen left or right.
- Pressing the up or down arrow key moves the media in or out of the plotter.
- Pressing the PEN SELECT key accesses a menu to select a given pen from the pen changer.
- Pressing the PEN UP/DN key raises or lowers the pen.
Pressing the Online key during plotting switches the plotter off-line and suspends plotting.
Pressing the Online key again will cause plotting to resume at the point of suspension.
When the plotter is on-line after media has been loaded (see LOAD later in this chapter), the LCD will read:Arrow Keys
USER n ONLINE
DESELECTED or SELECTED
where n is the number of the user configuration currently in effect (see "User Select Menu" later in this chapter). The LCD will show "DESELECTED" until the plotter is selected by software on the host computer.
Note: The plotter does not show "DESELECTED" when it is in the HP-GL or HP-GL/2 mode and the LINE STATUS parameter is set to STANDALONE (see these parameters under "Configuration Menu" later in this chapter). These latter settings hold the plotter in its selected state whether software selection commands are received from the host computer or not.
The arrow keys allow you to scroll through lists of items in the LCD window. When arrows appear with an item in the LCD window, they indicate that the up, down, or left, right arrow keys can be pressed to display the other items in the list. For example:Digitizing Points
Both vertical and horizontal lists are circular, so pressing an arrow key repeatedly will display the first item in the list after the last item is displayed.
The arrow keys can also be used to move the pen carriage and media manually. If the control panel is in the list mode (items with arrows are displayed on the LCD), press the Online key to exit the lists and enter on-line mode. From the on-line mode, take the plotter off-line by pressing the Online key. While the plotter is off-line, pressing the left and right arrow keys will move the pen carriage in the direction of the arrows; pressing the up and down arrow keys will move the media in the direction of the arrows. Movement is slow (4 mm/s) when an arrow key is first depressed. After the key has been held down for about 1 second, movement becomes rapid (25 mm/s).
Note: Without media loaded, pen movement is restricted to Engineering A size (8.5x11 inches, 216x276 mm).
The plotter's digitizing mode can be initialized by software control from the host computer when the plotter is on-line and selected. In this mode, the plotter will transmit the x-y coordinates of the pen to the host computer, allowing its software to read point positions from the loaded media.Enter Key
When using the DM/PL plotting language, the LCD shows "DIGITIZE: ENTER" and goes off-line when the plotter receives a Digitize command from the host computer. Use the left and right arrow keys to position the plotter's pen over the point to be digitized, then press the Enter key to send the point's coordinates. The plotter will automatically return to on-line and selected operation.
When using the HP-GL or HP-GL/2 plotting language, the LCD shows "DIGITIZE REQUEST" when the plotter receives a Digitize Point command. Press the Online key to set the plotter off-line. Use the <-- ↑ ↓ --> arrow keys to position the plotter's pen over the point to be digitized, then press the Enter key to send the point's coordinates. The plotter will automatically return to on-line and selected operation.
The Enter key selects the setting or operation displayed in the LCD windows for use or execution.Pen Up/Dn Key
The Pen Up/Dn key raises and lowers the pen when the plotter is off-line. If there is no pen in the carriage, pressing the Pen Up/Dn key causes the plotter to retreive the currently selected pen from the pen changer (if the pen changer is installed and is in the lowered position).Pen Select Key
Note: After approximately two seconds of no pen movement, the plotter will automatically raise a lowered pen to prevent ink from bleeding on the media, until the pen is moved again. If the pen is not moved for the period set for the AUTO-CAPPING parameter (see under "Configuration Menu" in this chapter), the plotter will return the pen to its pen changer stall. To restore the currently selected pen to its previous position on the media, press the Pen Up/Dn key or an arrow key.
When the plotter is off-line, pressing the Pen Select key allows you to select a pen from the pen changer. After pressing Pen Select, press the <-- --> keys until the desired pen number is displayed on the lower line of the LCD, then press the Enter key. The plotter will retreive the selected pen from the pen changer.1-2 Key
The Pen Select key is also used in the Configuration Menu, covered later in this chapter.
When the plotter is on-line, the LCD window may prompt you to answer "1" or "2" in response to a query. For example:Setting New P1 and P2 Points
END OF PLOT; LOAD NEW MEDIA?
1=YES 2=NO
In this example, press the "1" key to answer "YES" and load new media, or press the "2" key to answer "NO" and continue using the sheet that is already loaded.
When the plotter is off-line and is in the HP-GL or HP-GL/2 eulation mode, the "1" and "2" keys can be used to set the P1 and P2 points for HP-GL. Refer to Plot Orientations and Coordinates in Chapter 3 for the default locations for these points.Reset/Load Key
Note: Setting the P1 and P2 points is useful only if they are supported by your computer's plotting software. See your software manual or an HP-GL reference manual (listed in "Appendix B") for more information.
To change the location of the P1 and P2 points:
- Load media, and set the plotter off-line. The LCD will show:
1=P1 2=P2
<-- ↑ ↓ -->
- Press the "1" key to move the pen to the current P1 point. The LCD should show "SET P1". Use the arrow keys to move the pen to the new P1 point, then press the Enter key. To cancel the request to set a new P1 point, press the "1" key again before pressing the Enter key.
Note: The plotter does not automatically raise the pens during this operation. If the pen is down, lines will be drawn on the media.
- Press the "2" key to move the pen to the current P2 point. The LCD should show "SET P2". Use the arrow keys to move the pen to the new P2 point, then press the Enter key. To cancel the request to set a new P2 point, press the "2" key again before pressing the Enter key.
- Press the Online key to resume operation using the new P1 and P2 points. To restore the default location of these points, reset the plotter (see below).
The Reset/Load key sets the plotter off-line, suspends any other operation in progress, and displays the RESET/LOAD menu. Use the <-- --> keys to scroll through the list of functions until the desired function is displayed on the bottom line of the LCD. Then press the Enter key to execute the displayed function. Upon completion, the plotter goes online.LOAD
Select LOAD and press the Enter key to load new media for plotting. (The media must be in place under the pinch rollers, as described in "Chapter 3" under "Media.") The plotter will move the pen carriage left and right to scan the width of the media, and it will roll the media back and forth to scan the sheet length and set the pinch roller tracks.RESET
Note: The plotter will detect and attempt to use sheets up to 20 feet (6 m) long. However, for reliable tracking do not use sheets that are more than 2 inches (50.8 mm) longer than standard.
Technical Note: Loading additional sheets of the same size preserves any Clip & Scale Menu settings that you have made using that size of media. if the newly loaded sheet differs in size from the old sheet by more than 0.1 inch (2.54 mm) in the pen axis or 1.0 inch (25.4 mm) in the media axis, all Clip & Scale settings are reset to their default values.
Select RESET and press the Enter key to restore the plotter to its power-on settings. Clip & Scale Menu settings are reset to their default values. All plot data in the plotter's memory is cleared. If a sheet is currently loaded in the plotter, the LCD will query "LOAD NEW MEDIA?" Press the "1" key ("1=YES") to eject the current sheet or press the "2" key ("2=NO") to leave it loaded.ABORT
Select ABORT and press the Enter key to cancel a plot in progress without changing any other plotter settings. Clip & Scale Menu settings are not reset, unless a different size sheet is loaded (see "LOAD" above). If there is plot data in the input buffer, the LCD will show:REPLOT
CLEARING ABORTED
PLOT DATA....
The current plot is removed from the plotter's input buffer, but other plots in the buffer are retained. If a sheet is currently loaded in the plotter, the LCD will query "LOAD NEW MEDIA?" Press the "1" key ("1=YES") to eject the current sheet or press the "2" key ("2=NO") to leave it loaded.
Select REPLOT and press the Enter key to replot the last drawing plotted. If "REPLOT" is not displayed when you scroll through the list of Reset/Load functions, there is no plot available in memory to replot -- no drawing has been plotted since the plotter was switched on or reset, or the last drawing plotted was too large to fit completely into the plotter's input buffer.CUT
CUT is available for the DMP-162R plotter. When this option is selected, the present plot is cut from the roll. A load is not performed.Menu Key
The MENU key is used to select among several menus that configure the plotter. Pressing the Menu key sets the plotter off-line and allows you to access the menus shown in the chart below, which are described in the following section.Menus
Press the Menu key repeatedly until the menu you want to access is displayed on the top libe of the LCD. The list of menus is shown below. Note that you must press the Enter key to access the configuration parameters under CONFIGURATION or the submenus under CLIP & SCALE.User Select Menu
From any level in the menus or their options, you can press the Menu key to return to the list of menus at the top level. To exit the menus from any level, press the Online key to resume on-line operations or the Reset/Load key to use the Reset/Load functions.
The User Select menu allows you to select the active plotter configuration from among four internally stored sets of configuration parameters (USER SELECT numbers).LCD Contrast Menu
To select a configuration set for use, press the Menu key until "USER SELECT" is displayed on the upper line of the LCD. Then press the <-- --> keys until the desired USER SELECT number is displayed on the lower line of the LCD, and press the Enter key to activate it. The newly selected configuration set will be in effect for both on-line operation and editing using the Configuration Menu.
Note: An asterisk (*) is displayed on the LCD next to the current USER SELECT number.
Note: Activate the USER SELECT number for the set of configuration parameters that you wish to view or change before entering the Configuration Menu.
SELECTING MENUS
The LCD Contrast Menu lets you alter the contrast of the LCD. Press the Menu key until "LCD CONTRAST" is displayed on the upper line of the LCD. Then press the ↑ ↓ keys until the LCD characters are at their maximum legibility from your viewing angle.Configuration Menu
The configuration menu lets you access various sub-menus to configure the plotter parameters. To view or change configuration parameters, press the Menu key until "CONFIGURATION" is displayed on the upper line of the LCD, then press the Enter key. Use the ↑ ↓ keys to scroll parameter names in the upper line of the LCD windows until the desired parameter is displayed. Then use the <-- --> keys to scroll alternative values for that parameter in the lower line of the LCD window. To set the parameter to the value displayed, press the Enter key. If you do not press the Enter key, the parameter will remain set to the value displayed with an asterisk (*).PEN VELOCITY
The Configuration Menu parameters are shown in the chart below and each parameter is described below. The alternative values for each parameter are listed and separated by a "<-->" symbol. Factory default values are underlined. Both inch and metric values are listed for some parameters. The inch values for these parameters are displayed on the LCD only when the LANGUAGE parameter is set to DM-PL and the MENU UNITS parameter is set to ENGLISH.
Note: Configuration changes apply only to the USER SELECT number that is currently active (see "USER SELECT MENU" above).
Note: Configuration parameters apply to the plotter's DM/PL, HP-GL, and HP-GL/2 emulation modes unless indicated otherwise in the descriptions. Parameters that do not apply to the mode currently set by the LANGUAGE parameter are not displayed in the LCD window.
CONFIGURATION MENU PARAMETERS
1 <--> 2 <--> 4 <--> 6 <--> 8 <--> 10 <--> 12 <--> 14 <--> 16 <--> 18 <--> 20 <--> 22 <--> 24 <--> 28 <--> 32 <--> MAX IPS
or
30 <--> 50 <--> 100 <--> 150 <--> 200 <--> 250 <--> 300 <--> 350 <--> 400 <--> 450 <--> 500 <--> 550 <--> 600 <--> 700 <--> 800 <--> MAX MM/S
This parameter sets the pen-down velocity for each pen or pen group (see "PENS/GROUP" later in this chapter). To view or change the velocity of a pen or pen group, press the Pen Select keyuntil the desired pen number, or "ALL" for all eight pens, is displayed on the left side of the lower line in the LCD windows. The current velocity setting, in inches per second (ips) or millimeters per second (mm/s), appears to the right of the pen number. (For ALL pens, a question mark (?) will be displayed for the velocity setting if pens are currently set to different velocities.)PEN TIP SIZE
To change the velocity setting for the pen number displayed (or ALL pens), use the <-- --> keys to display the desired velocity. Then press the Enter key to select the displayed value.
The MAX velocity selection is 32 ips (800 mm/s) in the pen axis. But, unlike the other velocity selections, MAX does not limit the pen to a constant velocity, so diagonal pen moves are at 45 ips (1140 mm/s).
Note: Using MAX velocity for a pen, or using pens set to different velocities, may cause unintended variations in line widths.
.25 <--> .35 <--> .50 <--> .70 <--> 1.00 MM
This parameter tells the plotter the pen tip size for each pen or pen group (see "PENS/GROUP" later in this chapter). To view or change the pen tip size for a pen or pen group, press the Pen Select key until the desired pen number, or "ALL" for all eight pens, is displayed on the left side of the lower line in the LCD windows. The current pen tip size setting appears to the right of the pen number. (For ALL pens, a question mark (?) will be displayed for the pen tip size setting if pens are currently set to different tip sizes.)VELOCITY OVERRIDE
To change the pen tip size setting for the pen number displayed (for ALL pens), use the <-- --> keys to display the desired pen tip size. Then press the Enter key to select the displayed value.
Note: if the pen tip size settings are larger than the actual pen tip sizes, solid fills may show gaps. If the pen tip size settings are smaller than the actual pen tip sizes, solid fills may be excessively inked.
HOST CONTROL <--> IGNORE HOST
HOST CONTROL allows the host computer's plotting software to override the plotter's pen-down velocity.PEN ACCELERATION
IGNORE HOST causes the plotter to ignore all pen velocity commands from the host computer and use the current settings for the PEN VELOCITY configuration parameter.
IGNORE HOST can be used in conjunction with PEN VELOCITY to slow down a plot to improve its quality in some cases.
1.0 <--> 2.0 <--> 3.0 <--> 4.0 g
This setting limits the maximum acceleration of the pen when it is down.
MEDIA VELOCITY
1 <--> 2 <--> 4 <--> 6 <--> 8 <--> 10 <--> 12 <--> 14 <--> 16 <--> 18 <--> 20 <--> 22 <--> 24 <--> 28 <--> 32 IPS
or
30 <--> 50 <--> 100 <--> 150 <--> 200 <--> 250 <--> 300 <--> 350 <--> 400 <--> 450 <--> 500 <--> 550 <--> 600 <--> 700 <--> 800 MM/S
This setting limits the maximum media velocity. The default value for the DMP-161 plotter is 32 inches per second (800 mm per second), as shown above. The default value for the DMP-162 and DMP-162R, however, is 24 IPS (600 mm per second).NUMBER (#) OF PENS
Lowering this limit can be used to improve tracking with some media types. However, setting the media velocity significantly lower than the pen velocity may cause differences in the line widths of media axis and pen axis vectors.
1 <--> 2 <--> 3 <--> 4 <--> 5 <--> 6 <--> 7 <--> 8
When you are using the pen changer, set this parameter to the number of pens available for use during plotting. If the pen changer is not installed or is in the inactive (raised) position, the number of pens is assumed to be one regardless of this parameter's value.
If the plotting software on the host computer requests a pen number greater than the value set for this parameter, the plotter substitutes a lower numbered pen, as shown in the following table.
PENS/GROUP
1 <--> 2 <--> 4 <--> 8
1 <--> 2 <--> 4 <--> 8
Pen groups can be set up to spread pen usage over a group of pens, preventing the pens from drying out, and allowing them to wear more evenly. If a value other than OFF is set for the PENS/GROUP parameter, adjacent pens are grouped as shown in the table below.
PENS/GROUP
SettingSelect Pen Number
(Requested)Pen Numbers Used by Plotter 2 1 1 or 2 2 3 or 4 3 5 or 6 4 7 or 8 5 or greater * 4 1 1, 2, 3, or 4 2 5,6,7, or 8 3 or greater * 8 1 1, 2, 3, 4, 5, 6, 7, or 8 2 or greater * * If the "select pen" number is greater than the number of available groups, the number of groups is subtracted from the "select pen" number until the result is within the range of available groups. For example: with PENS/GROUP=2, there are 4 groups. A request for pen number 6 will be assigned to the second group (6-4=2), consisting of pens 3 and 4.
When the plotter first receives a "select pen number" command from the host computer, it uses the first pen in the group assigned to that pen number (shown in the table above). After plotting with a pen for 100 meters (measured by the major axis of each vector), the plotter will exchange it for the next pen in the same group. When all of the pens in the group have been used, the plotter will choose the first pen in the group again.LANGUAGE
DM-PL <--> SCAN-CAD <--> HP-GL <--> HP-GL/2
Set the LANGUAGE parameter to the plotting language used by the software on the host computer. If the software specifies plotter models instead of plotting languages, choose your DMP-160 Series plotter model if it is listed. If the DMP-160 Series is not listed, choose an emulated plotter for your software and a corresponding plotting language for the plotter using the following table.
Plotting Language Emulated Plotter Model DM/PL DMP-160 Series, DMP-60 Series HP-GL HP 7585B, 7580B, 758x Series HP=GL/2 HP DraftMaster RX / SX / MX 7595B
To use the optional SCAN-CAD accessory, set LANGUAGE to SCAN-CAD.
Note: No other configuration parameters are available when LANGUAGE is set to SCAN-CAD.
ON <--> OFF
When OPTIMIZATION is OFF, the plotter does not sort plot data (plot instructions) received from the host computer.MENU UNITS
When OPTIMIZATION is ON, the plotter performs pen and vector sorting on incoming plots to speed up plotting.
Many plotting programs offer their own plot optimization, sometimes at differetn levels. Choosing pen sorting (only) in the plotting software and leaving OPTIMIZATION ON for the plotter will usually maximize plotting speed.
ENGLISH <--> METRIC
Select METRIC to display menu settings in millimeters, or ENGLISH to display them in inches when LANGUAGE is set to DM/PL. Menu settings are displayed in millimeters for the HP-GL and HP-GL/2 modes. Plotters shipped to locations in the U.S. and Canada are set to ENGLISH. All other plottes are set to METRIC.AUTO-CAPPING
DISABLE <--> 15 <--> 30 <--> 60 <--> 120 <--> 240 <--> 480 S
Unless disabled, this parameter sets the time limit, in seconds, for inactivity before the plotter beeps and automatically returns the current pen to its stall in the pen changer. This helps prevent the ink from drying on the pen tip by "capping" the pen after finishing a plot or while the plotter is off-line. A typical setting for stainless steel and tungsten tip drafting pens is 15 seconds.PEN PAUSE
To restore the currently selected pen to its previous position on the media during off-line operations, press the Pen Up/Dn key or an arrow key.
DISABLE <--> ENABLE
When PEN PAUSE is enabled and the pen changer is in the inactive (raised) position or is not installed, the plotter will wait for you to manually change pens after it receives a pen change command from the host computer. The LCD window will prompt you to press the "1" key to resume plotting at the point of suspension.ORIENTATION
NORMAL <--> ROTATED
When ORIENTATION is set to NORMAL, the x-axis of the plot is aligned with the long dimension of the media. When ORIENTATION is set to ROTATED, the y-axis of the plot is aligned with the long dimension of the media. See ORIENTATION in Chapter 3.
Technical Note: The HP-GL or HP-GL/2 Rotate (RO) command will override the ORIENTATION setting until the plotter is reset or receives an Initialize (RO IN) command. When the CHART COMMANDS configuration parameter is set to DMP-60 EH/EF, the DM/PL Full Chart (EF) and Half Chart (EH) commands will override the ORIENTATION parameter.
ADDRESSING
.001 INCH <--> .005 INCH <--> .025MM <--> .100MM <--> NORMALIZED
This DM/PL parameter sets the plotter's default user addressable resolution. If NORMALIZED is selected, the plotter automatically scales a plot to fit on the current media size is the plot uses DM/PL Coordinate Addressing (EC0) units. Plotters shipped to locations in the U.S. and Canada are set to .001 INCH. All other plotters are set to .025 MM.
TEXT FONT
F0 <--> F1 <--> F2 <--> F3 <--> F4 <--> F5 <--> F6
This DM/PL parameter sets the plotter's default text font (character style). The FONT DEMO plot, accessed through the Internal Plots Menu (covered later in this chapter), illustrates the available fonts.TEXT SPACING
Note: For character sets G8, G9, and G10, only font F0 (single stroke) is available.
PROP. <--> VARIABLE <--> NON-PROP.
This DM/PL parameter sets the plotter's default character spacing.CHARACTER SET
PROPORTIONAL selects proportional character spacing---character width varies according to the character, but spacing is adjusted so that the whole character string is the same length as an identical NON-PROPORTIONAL (fixed) string. This setting is the default and recommended value for all text fonts except script (F6).
VARIABLE selects proportional character spacing---character width varies according to the character, and spacing is not adjusted to a fixed string length. This setting is the recommended value for the script (F6) text font.
NON-PROPORTIONAL selects fixed character spacing---each character is centered in a character cell of uniform width. This setting is sometimes useful for characters that are aligned in columns.
G0 <--> G1 <--> G2 <--> G3 <--> G4 <--> G5 <--> G6
This DM/PL parameter sets the plotter's default character set. The FONT DEMO plot, accesed through the Internal Plots Menu (covered later in this chapter), illustrates the available character sets.OPEN FONTS
FILLED <--> NOT FILLED
This DM/PL parameter selects FILLED or NOT FILLED as the default style for fillable DM/PL fonts (F1, F2, F3, and F4).ZERO CHARACTER
PLAIN <--> SLASH <--> DOTTED
THis parameter selects one of three different styles of zero characters for use in plotting text with most fonts. The DM/PL Katakana font and some HP-GL fonts ignore this selection.BAUD RATE
2400 <--> 4800 <--> 9600 <--> 19200 <--> 38400
The plotter's BAUD RATE must be set to the same baud rate as the software (plotting software or the operating system) controlling the host computer's serial port. For maximum performance, choose the highest baud rate supported by all of the following: the host computer's serial port (hardware), the host computer's software, the plotter's BAUD RATE parameter.PARITY
Note: Make sure that you set serial interface parameters on your host computer for the serial port (*COM* port) to which the plotter is connected.
EVEN <--> MARK <--> NONE <--> ODD
The plotter's PARITY must be set to the same parity type and number of data bits as the software controlling the host computer's serial port.
Note: Set the host computer's software to "one stop bit" for any of the plotter's parity settings.
Note: Windows 2000 requires the data bits be set to 8.
Plotter PARITY Setting Host Computer Settings Parity Data Bits NONE None 8 MARK Mark 8 EVEN Even 7 ODD Odd 7
RTS/DTR
TOGGLE <--> HIGH
The plotter's RTS/DTR ("handshaking" or "flow control") parameter must be set to the same type of handshaking as the software controlling the host computer's serial port.LINE STATUS
When RTS/DTR is set to HIGH, the plotter uses standard control codes, XON and XOFF, to control data flow. The signals on the RTS/DTR (Request To Send/Data Terminal Ready) lines of the RS-232C interface are constantly held high. This method is usually referred to as "software" handshaking.
When RTS/DTR is set to TOGGLE, the plotter changes the signal on the RTS/DTR lines to control data flow. This method is usually referred to as "hardware" handshaking.
STANDALONE <--> EAVESDROP
DM/PL ERRORS
The LINE STATUS parameter simulates the function of the STANDALONE/EAVESDROP switch on HP model 758x plotters. This parameter applies only to the plotter's HP-GL and HP-GL/2 emulation modes.
In the EAVESDROP mode, the plotter is not selected at power-on and must be explicitly selected for use by the host computer's software. In the STANDALONE mode, the plotter is automatically selected at power-on. Choose the setting required by the plotting software on the host computer.
IGNORED <--> REPORTED
DMP-162R Configuration Menu
When set to REPORTED, this parameter allows the plotter to display DM/PL error messages in its LCD window. The most common use for the REPORTED setting is to troubleshoot the interface link between the plotter and the host computer. After a link is established, IGNORED should be selected.
Note: If your plotting software uses automatic baud rate selection and DM/PL ERRORS is set to REPORTED, error messages will be displayed as the software attempts to match baud rates with the plotter.
CHART FEED
Using the DMP-162R, the Configuration menu lets you view additional sub-menus to control the feeding and cutting of roll-feed media. These additional sub-menus, not displayed for other plotter models, are discussed in the following paragraphs.
CUT SHEET <--> FULL ROLL <--> HALF ROLL <--> MANUAL ROLL
The CHARTFEED parameter selects the mesia type for the DMP-162R plotter. Be sure to match the CHART FEED setting with the type of media you are using in the plotter. Otherwise, media loading errors will occur.LOAD DELAY
The CUT SHEET setting selects cut-sheet media, and when it is selected, the DMP-162R operates exactly like a DMP-162. FULL ROLL should be selected when the sheet size is full size. HALF ROLL should be selected if the sheet is half size. MANUAL ROLL also selects roll media as the media type, but prompts the user each time a sheet is loaded to press the up and down arrow keys to adjust the sheet length. The longest plot that can be selected with this setting is 20 feet.
0 <--> 1 <--> 2 <--> 4 <--> 6 <--> 6 <--> 10 <--> MIN
The LOAD DELAY parameter sets the time (in minutes) you wish to allow the roll media to stablize after it is pulled from the roll.
CUT DELAY
2 <--> 3 <--> 4 <--> 5 <--> 6 <--> 7 <--> 8 <--> SEC
The CUT DELAY parameter sets the time (in seconds) you wish to allow the roll media to dissipate its static charge after it is pulled from the roll.
Service Mode Menu
The DMP-160 Series plotters' service mode adds tests and functions to the Configuration Menu that are useful for service technicians, but are not needed for normal operations. This Service Mode Menu is discussed in detail in Chapter 5.
Clip & Scale Menu
QUICK SCALE
The Clip & Scale Menu has sub-menus that let you locate, scale clip and/or mirror your plot anywhere on the media plotting surface. Note that this menu is not available if SCAN-CAD is selected as the LANGUAGE in the Configuration Menu.
To select the Clip & Scale Menu, press the Menu key until "CLIP & SCALE," is highlighted, then press the Enter key.
To select a sub-menu, press the up and down arrow keys until the LCD displayes the desired sub-menu on the upper line. Then use the <--> keys to scroll the menu options in the lower line of the LCD. Press the Enter key to select the option displayed.

Note: "ENGR" AND "ARCH" refer to U.S. standard engineering and architecture sezes; "DIN" and "OVRSZ" refer to DIN/ISO standard sizes. See the "STANDARD MEDIA" tables in Chapter 3 for more information.
When QUICK SCALE is OFF, the plotter does not scale plots to the currently loaded media size -- smaller plots are plotted smaller than the media and larger plots are clipped (cut off).
To enable scaling, set QUICK SCALE to the original size of the plot to be scaled. The plotter will scale the plot to cover as much of the loaded media (less margins) as possible, without distorting the plot by changing its aspect ratio. Since the plotter automatically determines the size of the current media during loading, you do not have to specify the output media size.

You can use the CLIP function to specify a particular rectangular area to be plotted. Portions of the original plot outside of the rectangular area will not be plotted.SCALE LL
Use CLIP LL to VIEW or set the lower left corner point of the rectangular area. Use CLIP UR to VIEW or SET the upper right corner point of the rectangular area. If you select VIEW with the Enter ket for either corner point, the plotter will move the pen to the current location of the appropriate corner. To change either corner point, select SET with the Enter key, use the left, right, up, and down arrow keys to move the pen to the desired corner point, then press the Enter key to set the new corner point.
The CLIP points default to the corners of the entire available plotting area at power-on or after a reset.

You can decide where on the media to place a plot by selecting a viewport. This is done by specifying where the lower left corner (origin) of the plot is to be. The point that selects the viewport is specified with the SCALE LL sub-menu SET VIEWPORT item. By moving the pen holder, you can move the viewport, or lower left corner of the plot, and determine the location for a plot when the plot code is sent.DRAW BORDERS
Like CLIP, the SCALE function can be used to limit plotting to a defined rectangular area. Unlike CLIP, the SCALE function scales the entire original plot to fit inside the rectangular area. The aspect ratio will be changed and the plot will be distorted if auto-scaling is not evoked (discussed below).
Use SCALE LL to VIEW or SET the lower left corner point of the rectangular area. Use SCALE UR to VIEW or SET the upper right corner point of the rectangular area. If you select VIEW with the Enter key for either corner point, the plotter will move the pen to the current location of the appropriate corner. To change either corner point, select SET with the Enter key, use the left, up, down, and right arrow keys to move the pen to the desired corner point, then press the Enter key to set the new corner point.
To SCALE a plot while maintaining its aspect ratio using auto-scaling, set the SCALE LL and SCALE UR points in the same axis (along an imaginary vertical or horizontal line). The side of the plot corresponding to the imaginary line will be set to the distance between the points, while the other dimension will be calculated to maintain the original aspect ratio.
CLIP WINDOW <--> VIEWPORT
Selecting CLIP WINDOW and pressing the Enter key will cause the plotter to draw a rectangle around the active plotting area currently defined by the CLIP function (namely, the "clip window"). Select VIEWPORT to have the plotter draw the borders of the active plotting area currently defined by the SET VIEWPORT and SCALE functions.
Internal Plots MenuThe Internal Plots Menu allows you to plot permanently stored internal plots. Press the <--> keys to select a plot from a list of available plots, then press the Enter key to begin plotting it.
The following table lists the internal plots and their primary uses.
