10MHz Reference
The BUC must receive a stable external 10MHz reference provided by a stable signal source such as a signal
generator, satellite modem or injected externally with a Bias T (for example, ABT6ARN/ABT6ARF
manufactured by Actox Corporation) or a similar bias T type.
Please make sure to check the sticker on the BUC for the appropriate power source before any power
connections are performed:
Powered via MS or IF Universal 15-60VDC
A universal powered unit is powered through a 2-pin MS mating connector (which is included with the BUC)
or IF input by an external minimum 60W 24VDC or 48VDC power supply source.
Powered via only MS 15-60VDC (optional)
MS only powered unit uses a 2-pin MS mating connector (which is included with the BUC) with either a
24VDC or 48VDC external power source with at least 60W.
Setting the L.O.
Switchable L.O. can be switched mechanically by using the micro switch under the protective bolt (marked on
the connector side of the BUC), or electronically if the BUC is equipped with M&C interface.
To change the L.O. mechanically, the protective bolt needs to be removed, and the micro switch pressed in
with any small object such as toothpick. If the BUC is equipped with M&C interface, the L.O. can be switched
electronically with the appropriate M&C command or via GUI.
Setting the TX and RX Frequencies
All transmit and receive frequencies are set in the modem. For a direct connection to an L-band modem follow
the manufacturer’s instructions on setting the transmit and receive frequencies.
Ensure that it is safe to transmit prior to enabling the transmission.
