INSTALLATION  
CABLE AND WIRING PREPARATION METHODS  
There are four methods of installing the LWM41 wall mount. Cables can be fed directly into the rear of the LWM41 or through  
the bottom of the mount arm. Conduit plates are supplied for added flexibility of installation. A rear entry, knock-off plate is  
supplied with the mount arm and a bottom entry, gland/conduit plate is supplied with the LRD41A11 Series receiver.  
Refer to one of the following sections to prepare wiring and cabling for your installation:  
Rear Entry Without Conduit  
Rear Entry With Conduit  
Bottom Entry Without Conduit  
Bottom Entry With Conduit  
REAR ENTRY WITHOUT CONDUIT  
1. Pull the cabling into and through the rear entry of the LWM41 wall mount. Feed the power cable through the right side of  
the mount and the video/auxiliary/alarm cables through the left side of the mount. Leave enough slack for connections,  
preferably four to six inches.  
2. Install LWM41 wall mount (refer to the installation instructions supplied with the mount).  
3. Proceed to Installing the Switch Bracket.  
REAR ENTRY WITH CONDUIT  
1. Secure the cable conduit to the block-off plate supplied with the LWM41 wall mount.  
2. Pull the cabling into and through the rear of the mount. Feed the power cable through the right side of the mount and the  
video/auxiliary/alarm cables through the left side of the mount. Leave enough slack to make all connections (preferably  
four to six inches).  
3. Install LWM41 wall mount (refer to the installation instructions supplied with the mount).  
4. Proceed to Installing the Switch Bracket.  
BOTTOM ENTRY WITHOUT CONDUIT  
1. Install LWM41 wall mount (refer to the installation instructions supplied with the mount).  
2. Remove the bottom plate of the mount arm and replace with the gland/conduit plate provided with the LRD41A11 Series  
receiver.  
3. Install the glands into the gland plate. Thread cabling/wiring through the glands. Do not install the BNC connector to the  
video cable before threading the cable through the gland. The BNC connector will not fit through the PG-13 gland. Do not  
use a gland sealing compound at this time.  
4. Feed the power cable through the right side of the mount and the video/auxiliary/alarm cables through the left side.  
Leave adequate slack for connections.  
5. Tighten the glands and secure the gland/conduit plate to the bottom of the mount arm.  
6. Install the BNC connector to the video cable.  
7. Proceed to Installing the Switch Bracket.

INSTALLING THE LRD41A11 SERIES RECEIVER  
NOTE: The LRD41A1 Series receiver accommodates an additional electrical (coax) connection to the camera for camera synchro-  
nization, which is necessary when multiple cameras require frame synchronization.  
The receiver box attaches to the inside access panel of the mount.  
1. Refer to Figure 4 and install the mounting hardware for the LRD41A11 Series receiver.  
2. Connect the video BNC and the switch bracket power connector to the rear of the receiver box.  
NOTE: The power connector clicks and locks into place. After making the connection, move the power switch (located  
inside the mount arm) to ON. Check the power LED on the receiver box for confirmation of power. Then turn off the switch.  
3. Mount the receiver box to the access panel by simply aligning the two mounting holes on the bottom of the receiver box  
with the anchor and thumbnut hardware on the access panel (refer to Figure 4). After aligning the mounting holes/studs,  
simply slide the receiver box down over the anchor and thumbnut and allow the box to attach securely.  
4. Tighten the locking thumbnut stud to secure the box in place. Make sure the thumbnut is very tight.  
5. Refer to Figure 5 and connect the Legacy 37-pin, pan/tilt connector to the receiver box.

CHANGING CAMERA VOLTAGE  
Set the camera voltage jumpers for the voltage that the camera will use. Refer to Figure 6 for the locations and settings for the  
jumpers.  
WARNING: CAMERA DAMAGE POSSIBLE. You will damage your camera if you connect it to the wrong connector on an  
EH4700L or EH5700L Series enclosure. If your camera will use the same power as the enclosure, plug the camera into the  
CAM1 socket on the circuit board inside the enclosure. If your camera will use 24 VAC and the enclosure will use either 120  
VAC or 230 VAC, plug the camera into the CAM2 socket only.  
If your camera will use 24 VAC, do NOT plug the camera into the CAM1 socket or you will damage your camera. CAM1 has  
either 120 VAC or 230 VAC on it.  
BE CAREFUL – REMEMBER – CAM1 IS ENCLOSURE POWER. NEVER PLUG YOUR CAMERA INTO CAM1 IF THE  
CAMERA’S VOLTAGE IS DIFFERENT FROM THE ENCLOSURE’S VOLTAGE.

OPERATION  
CONTROL WITHOUT VIDEO  
With this feature, the receiver can detect Coaxitron® commands from the controller when no video signal is present. Control  
without video is mainly desired for the auxiliary function.  
NOTE: The MPT9000, and the CM8500 and CM9500 families of controllers will transmit Coaxitron commands without reception  
of video (composite sync) signal.  
TRANSIENT SUPPRESSION  
Transient suppression circuitry that has been designed into the LRD41A11-X receiver reduces the chance of interrupted  
operation or damage to the receiver due to voltage spikes on the power and signal lines. Transient suppression does not imply  
lightning suppression.  
AUTO/RANDOM SCAN OPERATION  
Depending on the type of control unit you have, auto and random scan can be operated in two ways:  
Use the Auto/Man switch or keys (if your control unit has these functions)  
Use presets  
Auto/Man Switch – The random scan and auto scan functions are controlled by the same momentary switch on the control  
panel labeled Auto and Man.  
The first activation of the switch to the Auto position puts the pan/tilt into random scan. In random scan operation, the pan/tilt  
travels between the preset limits with a random scan period of about 2 to 30 seconds, and a random dwell period of between 2  
and 30 seconds. Following a dwell period, another random scan period starts. The direction of this scan period is also randomly  
determined. When a pan limit is reached, scan direction reverses automatically.  
A second activation of the Auto switch puts the pan/tilt into continuous duty auto scan (limit switch to limit switch). After  
approximately 1/2 hour of auto scan, the circuit resets to random scan.  
Subsequent operations of the Auto switch while in random scan mode cause a shift to auto scan mode and start the 1/2-hour  
timer. Operating the Auto switch while in auto scan mode causes a shift to the random scan mode and zeros the 1/2-hour timer.  
Presets – Auto and random scan also can be started by programming presets. The presets work only when your system is  
configured for Extended (32-bit) Coaxitron mode.  
Refer to your controller documentation for programming presets.  
Preset 96 stops a scan.  
Preset 97 starts random scan.  
Preset 99 starts auto scan.  
Advantages of random scan:  
Because scan direction, scan period, and dwell period are unpredictable, unauthorized activities or intrusions are  
discouraged.  
Because of the reduced duty cycle, gear train wear, cable fatigue, drive motor wear, and temperature rise are reduced.  
These factors all contribute to higher system reliability and increased equipment life.  
TEST LOCAL CONTROL (TLC)  
This feature allows you to connect an LRD41TLC test local control (TLC) module to the receiver to test the control of pan, tilt,  
and lens functions locally. This is convenient for positioning limit stops, backfocusing, and troubleshooting the installation. The  
TLC module also allows positioning of the camera locally.  
To use the TLC module:  
1. Plug the 16-pin connector from the TLC module into the TLC connector on the receiver (refer to Figure 5). You can plug in  
the module when power for the receiver is turned on.  
2. Hold down the keys on the TLC module to operate the pan, tilt, and camera functions. The receiver does not have to be  
connected to other control equipment in order for the TLC module to work. If the receiver is connected to other control  
equipment, the TLC module will override any transmitter control signals from the other control equipment.
