CDR500 Wall Mount Repeater Station
Assembling the CDR500 Repeater Housing
6. Connect the type-N male connector of the
cable to the antenna connector of the internal
duplexer. Refer to Figure 2-4 on page 2-4.
7. Connect the type-N end of the RF cable from
the transmit radio to the appropriate port of
the duplexer.
8. Connect the type-N end of the RF cable from
the receive radio to the appropriate port of the
duplexer.
9. Tighten all of the M5 machine screws to
1.58 N-m (14 in.-lbs.) torque. Tighten all of the
6-32 machine screws to 0.68 N-m (6 in.-lbs.)
torque for the Tinnerman clips or 1.35 to
1.58 N-m (12 to 14 in.-lbs.) for Pemnuts.
Installing the Antenna Cable(s) and Radio
Power Cables
1. Place the assembled radio/duplexer bracket
module into the CDR500 repeater housing
close enough to the back wall to allow con-
necting the duplexer antenna bulkhead con-
nector(s) to the wall.
2. Remove the nut and lockwasher from the
type-N female bulkhead connector of the
antenna cable from the internal duplexer or
from the transmit radio.
3. Align the flat side of the bulkhead connector
with the straight side of the D-shaped hole in
the back of the CDR500 repeater housing.
4. Push the connector, from the inside to the out-
side, through the CDR500 repeater housing.
5. Secure the bulkhead connector to the CDR500
repeater housing using the nut and lock-
washer removed in Step 2, and torque to
2.25 N-m (20 in.-lbs.).
6. If the external duplexer cable kit, HKKN4001
is used, remove the hole plug from the outer
of the two remaining D-shaped holes in the
back wall. The hole plug may be discarded.
7. Repeat steps 2 through 5 to install the receive
radio external duplexer antenna cable.
8. Locate the longer dc power cable, with the 2-
prong "Ford" connector, from the power sup-
ply.
9. Plug the cable into the dc power connector of
the (lower) transmit radio.
10. Plug the remaining dc power cable into the dc
power connector of the (upper) receive radio.

Installing the Radio/Duplexer Bracket

1. Tilt the radio/duplexer bracket slightly
upward at the front end and slide the rear
notched mounting tabs on the radio/duplexer
bracket under the 8-32 nuts of the threaded
studs toward the back of the CDR500 repeater
housing.
2. Press the radio/duplexer toward the back of
the housing.
Do not yet tighten the back mounting
nuts to attach the radio/duplexer mod-
ule to the CDR500 repeater housing.
3. Slide the front mounting tabs of the radio/
duplexer bracket over the 8-32 studs. Reinstall
the 8-32 nuts, removed in Step 3A under "Dis-
assembling the CDR500 Repeater Housing"
on page 2-2, on the studs and tighten to 1.80 to
2.00 N-m (16 to 18 in.-oz.) torque.
4. Tighten the back mounting 8-32 nuts to 1.80 to
2.00 N-m (16 to 18 in.-oz.) torque.

Installing the Repeater Controller

1. Place the repeater controller bracket on a flat
surface with the open end up.
If you are using the Basic Repeater Control-
ler, before continuing:
• Remove it from its mounting tray
and replace it, upside-down, in
the tray for proper viewing when
the CDR500 repeater is mounted.
• Slide the tray up through the open
area of the bracket and into position.
2. Slide the repeater controller module, upside-
down, into the lower mounting position
(nearest the power supply).
3. Attach the repeater controller to the bracket
with two M5 x 0.8 x 8 T25 Torx, pan head,
machine screws, and torque to 1.58 N-m
(14 in.-lbs.).
Installing the Mounting Bracket for the
Repeater Controller
1. Place the assembled repeater controller
bracket into the CDR500 repeater housing on
top of the power supply. Tilt the module
slightly upward at the front end and slide the
rear notched mounting tabs of the bracket
