The ORS-8 allows to amplify the RS-485 signal from single transmitter (eg: DVR, control keyboard, PC computer) and split them to 8 independent RS-485 busses connected to the receivers (CCTV cameras). Device enables optical isolation among output buses and among output buses and input of the RS-485 signal. The basic application of the ORS-8 is protection of the CCTV system against damage due to any overvoltages existence on devices connected to the RS-485 bus (for example as result of lightning).
Device also allows to split a single RS-485 channel to 8 channels, that makes possible to use the star topology. This allows to connect each camera using the RS-485 cable up to 1200m length. So, the device helps arrange the CCTV system wiring and increases the maximal distances of the RS-485 signal transmission.
