Bias Tee Enable
In between the Option 1 and Option 2 plug in boards on the printed circuit board (PCB) there is a
jumper labeled “
Bias Tee Enable
”.
The factory default for this jumper is open (pins are NOT
jumpered together).
When the “Bias Tee Enable” jumper is in place (both pins connected), the bias tee voltage is
connected to the
RX ANT IN
receiver antenna input connectors (BNC and F). This voltage is
toggled on when in the RX ANT mode. Exception:
See Bias Tee Always On
Force Ground
On the rear internal PCB between the Option 2 and Option 3 By-Pass Plug In boards there is one
jumper called “
Force Ground
”. This jumper is normally left open (factory default).
NOTE: If this jumper is installed (pins are jumpered) the internal safety mechanism is
defeated. This safety mechanism is intended to protect the RTR-2 from transmit energy. DO
NOT use this jumper for typical amateur radio transmit functions.
This jumper is only used for applications where the RTR-2 is going to be used only with receive
antennas and any transceiver RF output is never connected to the RTR-2.
Never use with any type
of TRANSMIT antennas when the “Force Ground” jumper is installed.
