The HT401-104 series RS-485 control code distributors provide a maximum of 4 buffered RS-485 control code outputs to receivers and super domes from a single control code source input.

Features

■Ensure multiple controllers (DVR, matrix, keyboard controller, etc) simultaneously manage multiple controlled objects (speed dome, pan/tilt) tied in one bus-line, solving operation conflict & authority problem among controllers

■No need changing system setting, RS485 bus cascaded equipments can set different protocols & baud rates

■4 channels RS485 signal input

■1 channel RS485 signal output, control max. 128 pan/tilts or domes cascading

■No restriction of authority: whichever input port, firstly sending code to bus channel, will stand bus

■Support multiple equipments , operation with multi-level

■Twisted pair supports max. 1200 meters transmission

■Screw terminal connectors to make the installation easy and quick
