Wireless Network Controller (WNC) Issues

Wireless Network Controller (WNC) Issues

The WNC is small standalone wireless board. It's responsible for the wireless communication with the readers. If it's not working and this is VAC01 (the primary VAC), then there will not be any communication with the readers. The readers will still accept laundry cards and start machines, but they will not be able to send status/audit information and cannot take any commands, like vend price change requests.

The WNC is typically located near the top of the VAC. It is connected to the main control board using a 4-wire cable:


Normally it should have solid green power LED.




Case 1: Portal showing WNC Error, NEW INSTALLATION

Chances are something got unplugged (or damaged) during the installation. Check to ensure that the WNC board is present, the cable harness is connected, and the board has a green power LED, as shown above. If the cable harness is connected but there's no green LED, then there's some hardware malfunction. Contact support

Case 2: Portal showing WNC Error, existing location

Try issuing the Reboot Controller command remotely using the Portal. Newer systems resolve this automatically.


If the WNC error message is still remaining after the VAC has been rebooted, inspect the physically WNC board and check to see if it has it's power LED ON:


If the WNC is not receiving power, check to make sure it's wiring harness is plugged in, and fully seated, on both the WNC side, and the VAC control board side:

  


Case 3: No Errors, but there's no communication with the readers.

Ensure that the antenna clip is connected snuggly onto the WNC module:
