Function and Applicaion Introduction
Coaxial video multiplexer support multi-channel video signals and control data RS485 transmission only over one coaxial cable to 400-600M by way of Frequency Division Multiplexing. High-speed frequency division multipexing technology is adopted to avoid interference during video transmission. With all data transmission real-time and all images high-definition and no-delay. It's suitable for improvement of oil projects and building of new projects,
Features
1. High-speed Frequency Division Multiplexing technology is adopted so that several channel of signals can be multiplexed without transmission delay or interference.
2. The knob for adjusting transmission distance built in the Receiver support adjustments according to actual transmission distance for best signal output.
3. Built-in video adjusting button in the Transmitter, can cooperate with different video cameras.
4. With energy-saving circuit to achieve best energy efficiency ratio.
