Interface Information

This printer can communicate with a computer through either a DEC-423 serial interface or a Centronics parallel interface. The printer can use both interfaces at the same time when the I/F TYPE option is set to AUTO in the Set-Up mode.

This appendix provides information you may need for wiring your own interface cables or for programming computer-to-printer communications. Most users do not need the information in this appendix. To simply connect your printer to your computer, follow step 6, “Connecting the Printer to Your Host System,” in the Installation Guide, page 1-17.

Parallel Interface

This printer can communicate with the host in two different modes:

•Unidirectional

In this mode, the printer operates an industry standard 8-bit Centronics parallel interface.

•Bidirectional

This printer supports bidirectional communication per IEEE 1284 Standard Nibble mode. This printer can switch between Compatible Centronics and Nibble modes.

The interface connector is 36-pin Amphenol type with ESD protection.

The first table gives the connector pin assignments in Compatible Centronics mode, and the second table those in Nibble mode.

The data transmission rate reaches 5,000 characters per second at the minimum.

Designations of circuit direction are provided to indicate the source of the signals.
