Configure the various alarms that will switch on Indoor Unit relays as required. There
are two relays on each Indoor Unit. Each relay can be programmed to switch on
based on the occurrence of Payload or RF Link errors detected in the LOCAL/NEAR
and/or REMOTE/FAR Indoor Units. The user can visually select those errors that
will trigger the respective relays.
The following built-in test status can be monitored on a link:
Link Unavailable

6.5.1.5 Indoor Unit Loopback Controls
These controls allow you to set the loopbacks on the payload data.
• IU Loopback to Line - Used to loopback the data on the payload interface so
that incoming user payload data is sent straight back to the user. The
payload data does not go out over the RF link.
• IU Loopback to RF Link - Used to loopback the payload (Indoor
Unit)/Outdoor Unit data so that payload data arriving over the RF link is looped
and sent back across the RF link.
Perform a loopback as follows:
1. Select the Loopback Type by choice of arrows on the IU being tested.
2. Select the Loopback Timeout Time (in seconds). If enabled, the Loopback
state will cancel after Time seconds and the unit will return to normal
operation.
3. Click on the Loopback Timeout Enable checkbox.
4. Click on the Apply Changes button.
