The Communication Port is configured as a DCE device. To communicate with a DTE device such as a
workstation, use a standard (or straight-through) RS232 cable. To communicate with a DCE device, use
either a null modem adapter in line with a standard RS232 cable, or a null-modem serial cable.

RS232 Pin Configuration
Refer to this table if you want to make your own cables.
To do so, you must determine if your host RS232 device is:
To do so, you must determine if your host RS232 device is:
• 9-pin or 25-pin and
• configured as a DCE or DTE device.
• configured as a DCE or DTE device.
Serial Connector
The base connector is straight to the printed circuit board (PCB). This can power a peripheral device, such
as a mobile printer.
