SPEED DOME CAMERAS AND MOTOR UNITS KEYBOARD CONTROLLER KT-800 Multiple protocols supported on each channel;
RS-485/RS-422 communication (Tx: 3 ports, Tx/Rx: 1 port);
Number of controlled devices: max. 255; Max. distance: 1km (24 AWG standard cable).
RS-485 SPLITTER/OPTOISOLATOR ORS-8 Amplify and split RS-485 signals from 1 input to 8 outputs - each output line maximal distance: up to 1200m. There is an optical isolation among outputs and among input and outputs - protection against overvoltages and strokes.
