UI2 board revisions are supported by certain SW versions, i.e. new HW revisions may
not be supported by older SW versions. In case of such an incompatibility of HW and SW
the message "User Interface 2 HW failure" will be prompted.

4.3.6.1. VSWR Module Option

The VSWR module monitors the VSWR of the Node AM4 coverage port. The module
communicates with the controller through USB while measuring the forward and reverse
RF signal at the combiner output.

4.3.6.2. Battery Backup Option

The battery backup unit (BBU) including the battery pack is installed on top of the User
Interface 2 (UI2) board and located underneath the cover sheet. The BBU ensures that
the Node AM4 can log-off from a Network Management system in case the mains voltage
will be switched off.
