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
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.
