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.

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.

Intermec distributor.
