232C DB9 Connector Pin-out
Auxiliary Input/Output Connector
The user's input/output (I/O) interface must provide a DB9 plug connector to termi-
nate on the AI1401 Reader. The user must provide an actuator signal (trigger) that
turns on RF power for reading tags. After tag data is acquired, RF power should be
shut off to conserve power.
Note: When connecting the 10-1401-01 Reader or the 10-1401-04 Reader to a termi-
nal emulator, you may need to isolate Pin 9 of the I/O interface cable.
