Step 1. Installation - TX module

The TX module includes one of BNC video drop cable to connect our video source equipment (camera), one RS485 drop cable, and one power drop cable.

1. Screw an antenna onto the SMA connector on the back of the back of the TX module.

2. Locate the TX module close enough to your video source to connect to them. Use appropriate fasteners to anchor the TX module to the mounting surface.

3. Connect a BNC video/power extension cable (not provided) to the Video In and power drop cables of the TX module, then to your video source (camera) and 12 VDC power adapter (provided). Do not power on the TX module at this time.

4. Connect the RS485 drop cable of the TX module and to the local RS485 PTZ equipment you want to control, if needed.

Step 2. Installation - RX module

The RX module includes a BNC video drop cable to connect our video monitor/recording equipment (DVR), one RS485 drop cable, and one power drop cable.

1. Screw an antenna onto the connector on the back of the back of the RX module.

2. Locate the RX module close enough to your video recorder and RS485 controller to connect to them. Use appropriate fasteners to anchor the Transmitter module to the mounting surface.

The DVLX24WR 2.4 GHz Digital transmitter/receiver system is a reliable and exceptionally easy to install wireless communications link indoors or outdoors for video and RS485 communications. It includes these features: • Dynamic frequency selection to

avoid interference• Operating frequency range:

2.4000 GHZ to 2.4835 GHz• 3 dB omnidirectional antenna

A local area can accommodate up to 4 systems concurrently.

The DVLX24WR is composed of a 2.4 GHz digital transmitter and a digital wireless receiver. An optional hi-gain antenna is available to improve reception and extend the range of the communications link.

What’s in the box

• DVLX24WR transmitter (TX) and receiver (RX) modules• 12 VDC power adapter (2)• Antenna (2)

Selecting mounting locations for the Transmitter and Receiver modules

Select locations for mounting the transmitter and receiver modules with the following considerations:

• The transmitter and receiver modules can be up to 700 feet apart.• For best signal transmission, ensure that the Fresnel zone between the transmitter and receiver is free

of obstructions (see the diagram). Use the table below to approximate the minimum transmitter and receiver height from the radius (r) for the line of sight distance (d) and ground clearance.

Step 3. PAIRing the TX and RX modules

The TX and RX modules of each DVXL24WR product are factory configured to synchronize only with each other. Effective synchronization is achieved when the video carried through the system can be seen at the video recording or monitoring equipment connected to the RX (receiver) module, and an RS485 controller at the RX module can control a PTZ device connected to the TX module.

Synchronization of a single TX / RX module pair occurs automatically after the TX and RX modules are powered on. If synchronization is lost, it can be re-established by powering off, then powering on one or both of the modules. After powering off either module, wait 10 seconds before powering it on again.

To automatically synchronize a TX and RX module pair:

1. Plug the 12 VDC power adapter for the TX module into a standard 120 VAC outlet.

2. Plug the 12 VDC power adapter for the RX module into a standard 120 VAC outlet.

3. Verify that you can see video from your video source equipment (transmitter) at your video recorder.

4. Verify that you can control the remote RS485 (PTZ) device using your RS485 controller.

Multiple TX/RX systems

When setting up multiple DVLX24WR systems in the same vicinity, observe the following guidelines:

• Place RX modules at least 1 ft apart. • Power on each DVLX24WR TX and RX module pair one at a time and allow the pair to synchronize as

described above before powering on another DVLX24WR module pair.

NOTE If multiple DVLX24WR systems are setup in the same vicinity and pairing is lost between one or more TX/RX module pairs, power off the modules of the pairs that failed, then power on each pair one at a time and allow it to synchronize before powering on another pair.

Troubleshooting

Problem Possible Solutions

No video or audio

• Check power and video cable connections. • Verify that the camera and RX module are powered on. • Verify that video source signals are fed into the TX module• Verify that the recording / video monitoring / RS485 controller equipment is

functioning properly.

Interference in video

• Adjust the orientation of the antennas on the TX and RX modules. • Move the equipment away from devices that emit high radiation, such as

microwave ovens, wireless phones, etc.
