Serial Cable

Note: The serial cable port is located on the back of the desktop cradle.
Note: Assemble the AC Adapter and connect it to the desktop cradle. Verify the cradle has a dependable power source.
5. Connect a female DB9 connector to the male DB9 serial port on the back of the desktop cradle. The connection should
be finger tight.

Note: Pin 9 of this port does not have power capability. The desktop cradle can not support tethered scanners.
Indicators
