WARNING
Children operating or playing with a garage
door/gate opener can injure themselves
and others. The door/gate could close and
cause serious injury or death. Do not allow
children to operate the door control push
button or the remote control transmitters.
Install the receiver (and all control push
buttons) out of the reach of children and
away from all moving parts of the door/gate
hardware, but where the door/gate is
visible.
OVERVIEW
The Wiegand Receiver (CPWR) is a communication
device that transmits an information packet to an access
control unit such as a Sentex Telephone Entry System.
All receiver units utilize the latest in Chamberlain® rolling
code technology.
ACCESS CONTROL COMPATIBILITY
The CPWR outputs a 26-bit or 30-bit Wiegand format
compatible with Sentex access control systems.

Setting the Switches
Before making changes to any of the DIP switches, power MUST be disconnected from the receiver
(unplug the terminal block from J2 on the circuit board). Otherwise, your changes will not take effect.
Also, when setting the receiver’s DIP switches, refer only to the numbers silk screened on the PC board
(not the numbers on the DIP switch itself).

Before or while touching the circuit board, discharge any static electricity:
(1) Use a grounding strap OR
(2) Touch a cold, grounded, metallic pipe.
STEP 3: OUTPUT CODE FORMAT
The output code format switch settings are factory-set
for the 30-bit format (see Figure 2). To change the
settings to 26-bit, refer to Figure 3.
30-bit Switch Settings (Default):
S1, 3 = OFF or 0
S1, 2 = OFF or 0
S1, 1 = ON or 1

STEP 4: SET THE TRANSMITTER BUTTON RESPONSE(S)
There are three DIP switches used to set the
transmitter button response(s). See Figure 4
or Figure 5.
To disallow receiver response to transmitter
buttons, move the DIP switch(es) to the LEFT.
All button switches are factory set to ON.
 Switch S1, 1 controls Button #1 and
Button #4*
 Switch S1, 2 controls Button #2
 Switch S1, 3 controls Button #3
* If using a CPT4 transmitter, Button #4 reacts
to Button #1 settings, but uses a unique
identification number and facility code.

SETTING A FIXED FACILITY CODE (FFC)
1 The FFC switch must be in the ON
position (switch set to right).
2 Set the receiver’s facility code switches
(labeled 0-5) to match the facility code of
the access control system.
Refer to the switch settings chart in the
Appendix on page 6 for assistance.
NOTE: For installations that require the
facility code of the transmitters to be
passed to the access control system,
set the FFC switch to the OFF position
(set switch to left). Facility codes are
set in the transmitter at the factory to
avoid code duplication.

Facility code switches
6-15 are not used (must remain in the OFF or left position).

Installation and Wiring

 Antenna
 Installation and Operation Instructions
PARTS NOT SUPPLIED
 # 6 Mounting Hardware
 5-conductor shielded cable; 22 AWG wire
 Extension Kit (Optional)
STEP 1: MOUNT THE RECEIVER
Mount receiver to surface using #6 hardware (not
supplied). Refer to Figure 8 for receiver mounting
hole locations.
NOTE: Mount receiver with 18” of space above
the receiver for the antenna. Also, receivers
should be installed at least 5 feet apart to
avoid “cross-talk”.
STEP 2: CONNECT THE ANTENNA
Screw on antenna clockwise and slide rubber boot
down to meet o-ring (see Figure 7).
CAUTION
The outside of the antenna connector is not
ground. If using an extension kit, do not allow it
to contact a metal object.
1535F5
Figure 7: Antenna Attachment
STEP 3: CONNECT SIGNAL/POWER WIRES
Remove the terminal block from J2 on the circuit
board. Connect wires from the CPWR 6-pin
connector to the access control system. Refer to
Figure 8. Then re-insert the terminal block onto J2.
Wire the CPWR to the access control systems’
card reader port. Refer to the access control
system’s installation instructions for appropriate
wiring detail. A typical wire connection might
resemble the following:
CABLE SIGNALS WIRE COLOR
LED BROWN
DATA 1 WHITE
DATA 0 GREEN
+12VDC RED
COMMON (GND) BLACK
SHIELD SHIELD
NOTE: At power up, the CPWR will perform a
system check and produce a series of LED
flash sequences. This is normal.

Testing and Troubleshooting
STEP 1: CHECK THE POWER
Ensure that the red POWER LED is lit (see Figure 9). If
not, check your power connections and/or source. Voltage
reading should be within the range of 9VDC – 18VDC.
STEP 2: CHECK FOR RECEIVER OPERATION
The SIGNAL LED (refer to Figure 9) should be flickering
continuously, indicating that the RF receiver circuitry is
operating.
STEP 3: TEST THE TRANSMITTER/RECEIVER
Press the transmitter button previously set in step 4, page
3, within view of the receiver. If the DATA-yellow and
VALID-green LEDs do not light, review the Setting the
Switches and Connect Signal/Power Wires sections.
If the DATA-yellow and VALID-green LEDs
flash repeatedly and simultaneously, the
format settings may be incorrect (refer to
Output Code Format).
If reception of the transmitter’s signal is significantly
reduced, there may be strong RF interference from other
sources. Common sources of interference include
fluorescent lights, neon signs, mercury vapor lamps, arc
welders, and arcing power lines. Interference due to
lighting can be limited by having an electrician wire a
noise suppressor into the lamp, light, or sign circuit.
NOTE: It may be required to press the transmitter
button twice at first use.
RECEIVER LED REFERENCE
(Refer to Figure 9.)
SIGNAL – Red
This LED, when lit, indicates that the receiver has
detected the presence of RF energy. It is normal for this
LED to flicker continuously while the receiver is powered
up.
DATA – Yellow
This LED indicates that the receiver recognizes the
transmission data as coming from a Chamberlain®
transmitter with Passport technology.
VALID – Green
This LED indicates that the receiver is sending a
Wiegand format output to the access control system.
POWER – Red
This LED indicates that the receiver has power.
GRANTED – Green
This LED indicates that the access control system has
validated the transmitted code and has granted access.
STEP 4: ATTACH THE FRONT COVER
Attach front cover of receiver by turning screws clockwise
1/4 turn. Do not overtighten.
