Internal Jumpers
The
RTR-2
has internal jumpers that configure the placement of DC power (Bias Tee) onto the
RX
ANT IN
to power an active receive antenna. As delivered from DX Engineering, the RTR-2
internal jumpers are set for normal operation with no DC power on the antenna input connectors.
With the unit unplugged and no power connected, remove the two screws on each side of the cover
and lift the cover off.
The jumpers are small plugs that fit over and connect two of the pins on the associated header that is
soldered to the printed circuit board. The jumper is removed by pulling straight out and installed by
aligning with two pins and pushing straight in to fully seat the jumper. When a jumper is not used
and to avoid losing it, push it on so it only connects to one pin.
Looking inside the RTR-2 toward the rear of the unit is a printed circuit board.
Remove the Option 1 and Option 2 By-Pass Plug In boards to have a clear view and easily
check/change the jumpers. Refer to “
Removing Bypass Plug-in Boards
” for removal or installation
of these boards.
