Installing Internal Option Modules
The RTR-2 has positions for optional modules:
75 to 50 ohm Impedance Transformer Plug-in Module,
DXE-IT-PM
Receiver Guard Plug-in Module,
DXE-RG5000HD-PM
Receive Preamplifier Plug-in Module,
DXE-RPA-2-PM
Remove the cover from the RTR-2. Looking at the rear of the unit from the inside, you will see the
three Bypass Plug-In boards installed as shown below. When an optional board or boards are not
installed, the jumper boards (labeled as “Bypass Plug In”) must be in place as shown below.
Option 1 - The Top position is where the 50-75 ohm Transformer Module
DXE-IT-PM
is installed.
Option 2 - The Middle position is where the Receiver Guard
DXE-RG5000HD-PM
is installed.
Option 3 - The Bottom position is where the Receive Preamplifier
DXE-RPA-2-PM
is installed.
Note: Because of the power and switching requirements, the Receive Preamplifier
DXE-RPA-2-
PM
must be installed in only the Bottom position. When installing an optional module or a Bypass
board, ensure the pins are properly aligned and push the board fully in place.
