RS485 Sharer (BN-485H)
- 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
- RS485 bus cascaded devices can set different protocols & baud rates
- 8 channels RS485 signal input
- 6 channels RS485 output, each channel can control max. 128 pan/tilts or speed domes cascading.
- Total 8 levels control priority: #1 input port has top authority, #8 input port has lowest authority
- Support multiple similar devices (BN-485F/BN-485M) operation with multi-level
- Twisted pair supports max. 1200 meters transmission
