Setting Up Your Printer

2.2 Interfacing to the Printer

Depending on your application, the Printer can be set up in different ways. Table 2-1 lists the interface cables that should be used for each situation. If your application is not listed below, refer to Appendix B which contains the communications information necessary to connect the Printer to virtually any ASCII device.

Part Number	Description
556000	Printer to CRT Terminal (DB25P) RS-232
556001	Printer to PC 9 Pin (DB9S) RS-232
556002	Printer to PC 25 Pin (DB25S) RS-232
899516	Printer to PC Parallel Port (DB25P)

Table 2-1 Interface Cables

For most applications, the interface between the Printer and host device will be RS-232C. The cable necessary to connect the Printer to the host will be either a straight cable or a null-modem cable. This cable connects the DB-25 connector labeled ‘Serial Port’ on the back of the Printer to the serial data connector on the host device.

The pin configuration of the Printer for most descriptions of the RS- 232 interface on a DB-25 connector is Data Terminal Equipment, (DTE). Pin 2 is transmit, pin 3 is receive and pin 7 is ground.

The Printer supports both Xon/Xoff and CTS/DTR handshaking. Whenever the Printer is interfaced in a mode that does not use the CTS/DTR pins, a jumper should be placed on the PC side of the cable between pins 4 and 5 (CTS/RTS) to bypass the operation of those control lines. A custom cable must be obtained for this purpose.

For connection to most host systems, Xon/Xoff handshaking reduces the number of wires necessary in the interface cable. For interfacing RS-422 devices, the Xon/Xoff handshake is the only appropriate method.
