Kyocera S-9100DN Appendix C Host Computer Interface, Parallel Interface, Nibble high default

Appendix C Host Computer Interface

This appendix explains the signals used in the printer’s parallel and RS-232C interfaces. It also lists pin assignments, signal functions, timings, connector specifications, and voltage levels. The RS-232C protocols are also covered. Finally, it explains how to use the printer in a multi-computer environment.

This appendix explains the following topics:

•Parallel Interface

•Serial Interface

•RS-232C Protocol

•RS-232C Cable Connection

1. Parallel Interface

1.1Parallel Interface Communication Modes

The printer features fast data transmission with the parallel inter- face. The parallel interface mode can be activated from the op- erator panel.

See Changing Parallel Interface Modes on page 3-18.

NOTE

Use a parallel printer cable that complies with the IEEE1284 standard.

Nibble (high) [default]

High speed data communication is used in compliance with the IEEE1284 standard. Ordinarily, you should leave this setting un- changed.

Auto

The printer automatically changes its communication mode to the one the host computer is currently using.

Normal

The printer uses the standard communication method pre- scribed for Centronics interfaces.

High-speed

This mode enables faster data transmission between the printer and the host computer. (Select this mode if printing problems oc- cur when the printer is connected to a workstation.)

1.2 Interface Signals

The pins of the parallel interface connector carry the signals list- ed in the table in Parallel Connector Pin Assignment. Asterisks

in the table indicate signals that are low active. The table also in- dicates whether each signal is incoming or outgoing with respect to the printer.

[ ]: Signal names in the Auto mode and Nibble (high) mode (IEEE1284).

In the Auto mode and Nibble (high) mode, these signals are bi- directional.
