The extra Auxiliary I/Os on the 4-Port and 8-Port Boards are helpful for wiring Wiegand devices, however, any I/O pair may be used (including Contact and REX inputs).

To configure Wiegand devices in the Control Center, follow these steps:

1. Log in at control.openpath.com/login. For the European Control Center, go to control.eu.openpath.com/login.

2. Navigate to Devices > ACUs, then click on the ACU you want to edit.

3. Click on the Ports tab.

4. Click Port next to the first input of the I/O pair with a Wiegand device configured (e.g., Contact2 in example 1 or AUX1 in example 2).

5. Select Wiegand Device from the Input Type dropdown, then click Save.

This will label the subsequent input as Wiegand Device (Extended) and disable it from editing. Inputs cannot be changed if they are already assigned to an entry.

Once the Wiegand device is configured on the ACU, it can be assigned to an entry.
