A VDC COMMON
B VDC +
Receive In J4 and J5: The RX IN connectors are Type N, female connectors used to
connect the IF at L-band from the LNB’s to the Rx 1+1 Interface Module. 50Ω cables
are supplied with the Rx 1+1. The Rx 1+1 Interface Module supplies the LNB’s the
10MHz reference and VDC through these connectors.
Receive Out J6: The RX OUT connector is a Type N, female connector used to
connect the IF at L-band to the Modem. 50Ω cables should be used to connect to J6.
The Modem supplies through this connector the 10MHz reference signal for the LNB’s.
