Connecting In A Pc Environment; Connecting To The Parallel Port - Xante Accel-a-Graphix CT4 User Manual

Connecting in a PC Environment

In a PC environment without Ethernet, your computer communicates
with the controller via the parallel port or serial port.
Parallel communication is faster than serial communication, but it is
restricted to one-way communication from the PC to the controller.
Serial communication allows two-way communication between the
computer and controller.
Use the parallel port if your PC has a Centronics parallel port
available and it is within 10 ft. (3 m) of the controller. Use serial
communication when a parallel port is not available on the PC, if the
PC is between 10 ft. (3 m) and 25 ft. (7.6 m) from the controller, or if
your PC requires two-way communication with the controller.
If you are connecting via the serial port, skip to "Connecting to the
Serial Port" later in this chapter.

Connecting to the Parallel Port

You need to use the standard Centronics parallel cable included with
your controller to connect your PC and controller (fig. 2.17). The
parallel port on the rear of the controller uses a 36-pin connector.
The parallel port on your PC computer uses a 25-pin connector.
36-pin Connector
To Controller
Use the following procedure to connect your controller and PC using
the parallel port.
1. Plug the 36-pin connector end of the parallel cable into the
parallel port on the back of the controller (fig. 2.17).
2. Plug the 25-pin end of the cable into the parallel port on your
PC.
