1.2 Coaxial Cable Requirements
The SM and ODU must be connected using two runs (TX and RX) of
Comscope type 5729 coaxial cable, not more than 120 feet [36.5
meters] long.
In addition to conveying the IF signal, each coaxial cable passes DC
voltage supplied by the SM to power the TXB and LNB. The SM supplies
30V, 1.55A to the center conductor of the TX connector, and 30V,
150mA to the center conductor of the RX connector on the SM rear
panel.
Warning When
the SM is powered
on, DC voltage is
present on the rear
panel TX and RX
connectors.
