Data Communications

The CodeWriter 4500 Series printer provides a RS232 serial port for communications
to host systems. The DB25 female connector is located on the rear of the unit (see
Figure 2). The Operator Panel provides access to the serial ports operating
parameters.

Connecting to a Personal Computer

This procedure defines establishing a connection between a CodeWriter 4500 Series
printer and a Personal Computer with an IBM AT 9-pin connector.
Cable
This connection requires a cable with a DB25 male connector for the printer
and a DB9 female for the Personal Computer. This cable is available from
Datasouth (Part # 108965). Table 1 details the cable's wiring diagram.
Note: Proper operation only guaranteed for cables meeting
EIA/TIA-232-E electrical and mechanical specifications.
