Connecting Cables in a Single‐Slot 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
Working from the bottom connector up, connect the RF Module cables, as follows:
a
Connect the MOD N TX1/RX1 cable to the RF Module.
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 PRU door from closing.
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 TX0/RX0 cable to the RF Module.
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.
c
Connect the LVDS Cables to the RF Module.
i
Connect  the  MOD  N  DIV  LVDS  Cable  to  the  DIV  receptacle  of  the  RF  Module  by
inserting and sliding in until fully seated.
NOTE:
Always connect the Diversity LVDS Cable with the RF Module.
ii
Connect the MOD N PRIM LVDS Cable to the PRIM connector, following the same steps
as above.
NOTE:
Full insertion can be recognized by an audible click as the LVDS Cable Connector locks into the RF 
Module  Receptacle.  This  can  be  verified  by  lightly  pulling  back  on  the  LVDS  connector  while 
making sure not to depress the release trigger. When fully inserted, the cable should not be able 
to be removed from the receptacle.
d
Connect the Power Cable Connector to the PWR receptacle of the RF Module by inserting
and sliding in until fully seated.
NOTE:
Full insertion can be recognized by an audible click as the Power Cable Connector locks into the 
RF Module Receptacle. This can be verified by lightly pulling back on the Power Cable Connector 
while making sure not to depress the release triggers on the ends of the connector. When fully 
inserted, the cable should not be able to be removed from the receptacle.
