Product Description
Maximum transmission signal: 8 channel forward video signal and one channel Ethernet,
1 channel high-speed bidirectional RS485 signal; With 2 series of expansion interfaces. Each series is able to transmit maximum 4 channel bidirectional audio, or 4 channel bidirectional RS485, or 2 channel RS422, or 4 channel bidirectional KEY. The two series function can choose to be the same or different.
Technology Characteristics
-> Each interface use the routine or conventional habits of customers physical interface, such as the use of diameter 3.5mm audio socket, data (RS485, RS422, RS232) and the use of common terminal block for key.
-> Perfect lightning protection design. Lightning injuries can be effectively reduced.
-> Use the internal power supply, more reliable and easier to install.
-> Single fiber transmission, core fiber optional
-> PAL / NTSC / SECAM compatible, studio-level transmission quality.
-> Asynchronous data transmission rate up to 128Kbps or more.
