NOX Specific Tip:
Please make sure not to use PIN 1 on the CMU to supply the unit. The unit has a high peak current when
calls are initiated. On the CMU you can use the BUS supply voltage, or an external supply.
If an external power supply is used, please remember to connect ground on the Wiegand controller with
the external supply’s ground to make sure the Wiegand signals work correctly.

When the unit receives a call, it hangs up the call and sends the incoming phone number on the Wiegand
bus
Listening mode ON:
When Listening mode is ON the call will be answered and the welcome message is played.
The user can then input keys and finish by hitting the # key
The unit will play a message depending on the state of IN0 and IN1.
If the unit does not see a # key it will timeout with a message, and hang up.
