About the GPIO Interfaces

Accessing the Interfaces

74
The IF2 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 IF2 operations.
Each interface is electrically isolated from the IF2 and designed for
low voltage DC loads. The IF2 can also supply 12 VDC at 0.5 A 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 IF2 GPIO port. The
port uses a standard 25-pin serial cable. For port pin assignments, see
"Port Pin Assignments" on page
Intermec offers these GPIO accessories:
• The GPIO Terminal Block (P/N 203-726-xxx). Use this accessory
to connect devices to the IF2 GPIO interfaces. The block provides
access to the IF2 GPIO interfaces via standard screw terminals.
• The Light Stack Kit (P/N 203-858-xxx). This 3-color indicator
light and beeper connects directly to the IF2 GPIO port and is
triggered by the output interfaces. The kit includes a connecting
cable.
• The Sensor Kit (P/N 203-859-xxx). This motion sensor connects
directly to the IF2 GPIO port and triggers the input interfaces. The
kit includes a mounting bracket and connecting cable.
The Light Stack and Sensor Kit (P/N 203-860-xxx). This kit
•
includes the light stack, a sensor with mounting bracket, and
connecting cable.
