1、4 road, economic link in a SYWV-75-5 cable transmission 4 video and 1 reverse RS485 data signal;
2、YF-T604T broadband cable modulator using STM chip technology, frequency modulation, surface acoustic wave filter, single chip codec technology design, With out of band suppression, high band edge characteristics of strict, frequency locked stable features such as superior, mainly used in broadband cable monitoring system for video signal Transmission, and a control interface data demodulation
3、V1, V2, V3, V4 frequency (30~54MHz) video signal, SYWV75-5 distances of 800 meters;
4、 the product is less than 800 meters of road engineering supervision project four or over short distances in the distance
5、using a cascade connection, wiring simple, low cost, convenient construction, shorter hours, without debugging
