Serial Connection
When the mobile computer is inserted into the cradle, the mobile computer’s serial port connects to
the cradle’s serial port. The mobile computer can then use the cradle’s serial port to communicate
with an external device.
To provide serial communication between the mobile computer and a serial device, connect one end
of the 9-pin serial cable to the serial port on the cradle, and the other end to the serial port on the
serial device.
