Chapter 5 — Using the IF30 GPIO Interfaces
72 IF30 Fixed Reader User’s Manual
About the GPIO Interfaces
The IF30 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
IF30 operations.
Each interface is electrically isolated from the IF30 and designed
for low voltage DC loads. The IF30 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.
Accessing the GPIO Interfaces
You can access the GPIO interfaces through the control port on
the front panel of the IF30. The control port uses a standard 25-
pin serial cable. For port pin assignments, see “Port Pin
Assignments” on page 82.
You can also use the GPIO Terminal Block accessory to connect
devices to the IF30 GPIO interfaces. The block provides access to
the IF30 GPIO interfaces via standard screw terminals.
