Connecting To The Serial Port - Xante Accel-a-Graphix CT4 User Manual

If you need to connect another computer to the controller port, skip
to the section on connecting to the desired port later in this chapter.
Otherwise, skip to "Connecting to a Printer" later in this chapter.

Connecting to the Serial Port

To use the serial interface, connect the computer and controller; then
make sure the computer, controller, and applications are using the
same settings.
You need a standard null-modem serial cable to connect your PC and
controller (fig. 2.18). The serial port on the rear of the controller uses
a 25-pin (DB-25) connector. The serial port on your PC uses either a
25-pin connector or a 9-pin connector.
