Description
FHC-6400T/R series are the digital 4-ch video,duplex 4-ch data with audio transmitter/receiver. The Units shall support all-pattern video signal be capable of transmitting 4 channel up video signals ,4 channel bidirectional audio signals 4 channel bidirectional data signals on an optic fiber. Therein,10bit/20MHz digital sampling for video signal; 24bit/48MHz digital sampling for Audio signal; Data interface sustain electric stard, eg. RS232/RS422/RS485.The baud rate is limited in 0 Kbps100 Kbps. The series use the full-digital optical transmission channel, which could ensure the transmission signal in high quality. There are the power light, the light signal indicating lamp ,the video signal indicating lamp the data signal indicating lamp on the panel. So, It is easier for user checking the state of power, optical signal, videosignal data signals visibly. Taken altogether, the unit is a long-distance transfers system of video with data, audio in high performance high value.
