RS485 Sharer (BN-485M)
- 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 (BN-485F/BN-485H) operation with multi-level
- Twisted pair supports max. 1200 meters transmission
