Note
If the satellite profile is configured to use narrow band tracking
(recommended) a standard RS-232 cable can be used to connect the
ACU RS-232 port to the Remote control port of the VSAT modem. If the
satellite profile is configured to use modem RSSI tracking a proprietary
RS-232/Alarm cable must be used to connect the ACU RS-232 port to
the Remote control and Alarm port of the VSAT modem.
