CAUTION!

The standalone packages possess the flying leads which carry DC inputs and alarms. When connecting to these leads,
any unused wires should be wrapped with electrical tape to avoid shorting that could damage the unit.

The Tx standalone unit has built in bias-T for remote powering of the LNB or could be used to power Tx though the RF
connector, this feature can be enabled or disabled (Factory Preset) by moving the internal jumper, see picture below.
The Tx unit is normally fed via the two flying leads, the Red Wire is +8V

DC

to +24 V

DC

and the Black Wire is ground

or -. The flying cable also has a shield wire that can be connected to ground to help shield any external signals.
