Connecting the Cables
Connect the Mobile Base to the host computer or other device by plugging an RS-232 serial cable into the RS-232
Communications Port on the bottom of the Mobile Base. Plug the other end of the RS-232 serial cable into the correct port on
the host RS-232 device.
The wiring of your cable depends on whether the other device is set up as a DCE (Data Communications Equipment) or DTE
(Data Terminal Equipment) device.
The Mobile Base Communication Port is configured as a DCE device. To communicate with a DTE device such as a computer,
use a standard (or straight-through) RS-232 cable. To communicate with a DCE device, use either a null modem adapter in line
with a standard RS-232 cable, or a null-modem serial cable.
