CONNECTING PERIPHERAL DEVICES AND ESTABLISHING COMMUNICATIONS
MONOCHROME PRINTERS
You can connect your terminal to a wide variety of monochrome graphics and text printers; follow whichever of the installation procedures applies to your printer. You can connect these monochrome printers to the terminal:
• Tektronix 4644 Dot Matrix Printer
• Hewlett-Packard ThinkJet
• Hewlett-Packard LaserJet (4207 only)
• Monochrome text-only printers with a Centronics-style interface
• Monochrome graphics printers with a Centronics-style interface and Epson FX-80 graphics protocol
If you don't find your printer listed by name, or if you need more information than is provided here, the manual accompanying your printer should tell you its type of interface and graphics protocol; this should enable you to determine if your printer is compatible with this terminal.
Tektronix 4644 Dot Matrix Printer
Follow this procedure to connect the terminal to a Tektronix 4644 Dot Matrix Printer:
1. Plug the printer cable into the COPIER port. Secure the cable connector with the two clips attached to the port.
2. Put the terminal in Setup, and then tell the terminal which printer is connected to it by entering:
HCINTERFACE 3
3. Instruct the terminal to send a Carriage Return(~) at the end of each line by entering:
HCMONOCHROME 0
4. Save the settings in nonvolatile memory by entering:
NVSAVE
INSTALLATION AND SETUP
Hewlett-Packard ThinkJet
Follow this procedure to connect the terminal to a ThinkJet Printer:
1. Plug the printer cable into the COPIER port. Secure the cable connector with the two clips attached to the port.
2. Put the terminal in Setup, and then tell the terminal which printer is connected to it by entering:
HCINTERFACE 4
3. Instruct the terminal to send a Carriage Return/Line Feed combination(~ 4=) at the end of each line by entering:
HCMONOCHROME 1
4. Save the settings in nonvolatile memory by entering:
NV SAVE
5. Now, set the Mode Select switch settings at the back of the printer to the positions shown in Table A-3:

INSTALLATION AND SETUP
Hewlett-Packard LaserJet and LaserJet Plus Printers (4207 Only) Follow this procedure to connect the terminal to a LaserJet or a LaserJet Plus Printer:
1. Connect the printer's RS-232 communications cable to the terminal's PORT 0 or PORT 1. Secure the RS-232 cable connector to the port by tightening the two small connector screws.
NOTE
The LaserJet and LaserJet Plus require an RS-232 C cable with male connectors on both ends; Pins 1, 2, 3, and 7 must be straight-wired - that is, Pin 3 on one connector must be wired to Pin 3 on the opposite connector. You can order a suitable cable through Hewlett-Packard.
2. Put the terminal in Setup, and then tell the terminal that the printer is connected to it through either PORT 0 or PORT 1 :
• To connect to PORT 0, enter:
HCINTERFACE 5
• To connect to PORT 1, enter:
HCINTERFACE 6
3. Enter the following communications commands (For this discussion, we'll assume that you are connecting the printer to PORT 1; if you are connecting to PORT 0, substitute PO wherever you see P1):
PASSIGN P1 :,PPORT PBAUD P1:,9600 PBITS P1:,1,8 PPARn:v P1:,NONE PFLAG P1 :,CHAR
4. Save the setting in nonvolatile memory by entering:
NVSAVE
Considerations for a LaserJet Plus Printer. The LaserJet Plus has both a Centronics-type port and an RS-232 port. You can only connect the printer to the terminal using the printer's RS-232 port and one of the terminal's 2PPI ports (PORT 0 or PORT 1 ).
INSTALLATION AND SETUP
Other Monochrome Printers
If you are connecting the terminal to some other monochrome graphics printer that has a Centronics-style printer interface and supports Epson FX-80 graphics protocol, or to a monochrome text printer with a Centronics-style printer interface, follow this procedure:
1. Plug the printer cable into the COPIER port. Secure the cable connector with the two clips attached to the port.
2. Put the terminal in Setup, and then tell the terminal which printer is connected toit.
• For a graphics printer, enter:
HCINTERFACE 3
• For a text-only printer, enter:
HCINTERFACE 0
3. Now, make sure the terminal sends the proper line endings for whatever printer you are using. Find out what the printer expects by either checking the printer's manual or, if the printer has a line-ending switch, by checking the printer's switch setting.
Match what the terminal sends to what the printer expects. You can either change the printer's switch (if it has one) or change what the terminal sends.
• To instruct the terminal to send a Carriage Return/Line Feed combination (CR LF) at the end of each line (this is the default and is appropriate in most cases), enter:
HCMONOCHROME 1
If you choose 1 and it's the wrong setting for your printer, the copies you make will have an extra blank line following each line of characters (that is, single-spaced text will be double-spaced, and graphics will have an extra blank line after each printed line).
• To instruct the terminal to send just a Carriage Return at the end of each line, enter:
HCMONOCHROME 0
If you choose 0 and it's the wrong setting for your printer, all your lines of text or graphics will print on the same line - resulting in one unreadable black line.
4. Now, save the settings in nonvolatile memory by entering:
NVSAVE
INSTALLATION AND SETUP
4510 COLOR GRAPHICS RASTERIZER (4207 Only)
1. Connect the rasterizer's RS-232 communications cable to one of the terminal's 2PPI ports (PORT 0 or PORT 1). (For this discussion, we'll assume the rasterizer is connected to PORTO; if you are connecting to PORT 1, substitute P1 wherever you see PO.) Secure the RS-232 cable connector to the port by tightening the two small connector screws.
2. Connect the 4691 or 4692 Copier to the rasterizer, and turn on both the rasterizer and copier.
3. Put the terminal in Setup and enter:
PASSIGN P0:,4510
