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.

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.
