Connecting Cables in a Single-Bay RF Module Installation
1
Position the cables so that they are under the right edge of the RF Module, pointing up.
2
Follow the rules listed in
.
3
Connect the RF Module cables, in the order shown below. As you work, refer to the graphic that corresponds
to the RF Module being installed into a single bay of the PRU: for a Single-Bay RF Module, refer to

a
Connect the MOD N TX0/RX0 cable to the RF Module (the RF cables and connectors are referred to as
MOD N TX0/RX0 where N equals A, B, C, or D).
MOD N TX0/RX0 where N equals A, B, C, or D).
i
Insert the N-Style Plug of the MOD N TX0/RX0 cable into the TX0/RX0 N-Style Jack of the RF Module.
ii
Turn the coupling nut of the plug clockwise to thread onto the jack and finger-tighten.
iii Torque coupling nut to 8 ±1 in-lbs to ensure full connection.
NOTE:
Insufficient torque applied to RF Module connections can result in elevated insertion/return loss and
higher than normal VSWR reported by the system.

b
Connect the MOD N TX1/RX1 cable to the RF Module (the RF cables and connectors are referred to as
MOD N TX1/RX1 where N equals B, C, or D).
MOD N TX1/RX1 where N equals B, C, or D).
i
If a TX1/RX1 RF Module connection is available, insert the N-Style Plug of the MOD N TX1/RX1 cable
into the TX1/RX1 N-Style Jack of the RF Module. If RF Module connection is not available, constrain
the MOD N TX1/RX1 cable to accompanying cables using a tie wrap so it cannot be pinched or prevent
the Remote Unit door from closing.

c
Connect the LVDS Cables to the RF Module—the LVDS cables labeled PRIM and DIV should always either
be connected to a RF Module or strain relieved to adjacent cables, as this protects the cable against
damage through misplacement. Maintain adequate strain-relief distances from the connection points to
the RF Module.

Connect the MOD N DIV LVDS Cable to the DIV receptacle of the RF Module by inserting and sliding
in until fully seated. Full insertion can be recognized by an audible click as the LVDS Cable Connector
locks into the RF Module Receptacle.

Connect the MOD N PRIM LVDS Cable to the PRIM connector, following the same steps as above. Full
insertion can be recognized by an audible click as the LVDS Cable Connector locks into the RF Module
Receptacle.

iii Ensure the two LVDS cables are fully seated and latched into their respective receptacles on the RF
Module by lightly pulling outward on the connectors. If fully seated and locked into position, the cable
connectors will not slide back out.
