Host I/O Interfaces
The printer provides connections on the rear panel for the following host I/O
interfaces:
• Centronics Parallel or IEEE 1284 Parallel Interface
• Dataproducts Parallel Interface
• Serial Interface (RS–232 or RS–422)
• PrintNet Ethernet Interface (if installed)
• Coax/Twinax Interface (if installed)
The parameters for each interface are selected through the control panel via the
“Host Interface” menu as described in Chapter 3, “Configuring the Printer”.
Interfaces are only simultaneously active if in Autoswitching.
The location of the interface connectors is shown on page 2–17 in Chapter 2,
“Setting Up the Printer”.
You must supply the interface cable to connect the printer to your host computer.
To facilitate the choice or manufacture of an interface cable for your application,
pin assignments for the Centronics, Dataproducts, serial, and IEEE 1284
interfaces are provided in this appendix.
Centronics Parallel Interface
This interface enables the printer to operate with controllers designed for buffered
Centronics printers. The interface is capable of transferring up to 200,000
characters per second. The maximum cable length from the controller (host
computer) to the printer is 15 feet.
Centronics Interface Connector Pin Assignments
The printer provides a 36–pin D–shell connector on the rear panel for connection
of a Centronics parallel interface cable. Table B–1 lists the pin assignments of the
Centronics interface connector.
