Accessing the Interfaces

126
The IF5 has four general purpose input and output (GPIO)
interfaces. You connect external controls such as motion sensors
or indicator lamps to the GPIO interfaces, which can then trigger
IF5 operations.
Each interface is electrically isolated from the IF5 and designed
for low voltage DC loads. The IF5 can also supply 12VDC at
0.5A to external devices.
How the inputs and outputs are used depends on the RFID
application software being used in the system. You need to
coordinate input and output control wiring with the software
developer.
You can access the GPIO interfaces through the control port on
the front panel of the IF5. The control port uses a standard
25-pin serial cable. For port pin assignments, see
Assignments" on page 137.
You can also use the GPIO Terminal Block accessory to connect
devices to the IF5 GPIO interfaces. The block provides access to
the IF5 GPIO interfaces via standard screw terminals.
