Date：2019-07-30|Brief：Raytrans provides high-performance, integrated central and remote solutions. The central end features an integrated audio/video dispatch switch IDM OMP2000-4E1-60 with dual Gigabit optical ports. The remote end uses IDM GTD442, which offers two physically isolated wire-speed Gigabit Ethernet ports (typically one for video surveillance, the other for measurement data transmission, control data transmission, etc.), four audio channels for telephone interface, intercom interface, public address broadcast interface, wireless intercom relay interface, etc., and two RS485 interfaces that can be aggregated to the central end's serial server card and converted to Ethernet interface for connection to the data server.
