To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is not connected BEFORE installing the
receiver.
To prevent possible SERIOUS INJURY or DEATH from a moving
gate or garage door:
• ALWAYS keep remote controls out of reach of children.
NEVER permit children to operate, or play with remote
control transmitters.
• Activate gate or door ONLY when it can be seen clearly,
is properly adjusted, and there are no obstructions to
door travel.
• ALWAYS keep gate or garage door in sight until completely
closed. NEVER permit anyone to cross path of moving gate
or door.

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 (Figure 1),
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 circuit
board (not the numbers on the DIP switch itself).
1. Disconnect power to the receiver.
2. Turn screws counterclockwise 1/4 turn and remove front
cover.
3. Before or while touching the circuit board, discharge any
static electricity:
(1) Use a grounding strap OR
(2) Touch a cold, grounded, metallic pipe.
4. The output code format switch settings are factory-set for the
30-bit format (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
S1, 0 = ON or 1
26-bit Switch Settings:
S1, 3 = OFF or 0
S1, 2 = OFF or 0
S1, 1 = ON or 1
S1, 0 = OFF or 0
5. Set the transmitter button response(s).
• There are three DIP switches used to set the transmitter
button response(s) (Figures 4 or 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.
Left = OFF or 0
Right = ON or 1
