Automatic data flow control technology is adopted to automatically identify and control data transmission, automatically detect serial port rate, identify * and control data transmission direction, and the maximum communication rate is > 500kbps,
Bidirectional transmission, point-to-multipoint application, can simultaneously support one channel of bidirectional semi dual lrs-485 data, adaptive single multimode optical fiber zero delay automatic forwarding asynchronous transmission, RS-485 interface and optical fiber conversion,
Surge protection and electrostatic protection. The interface provides 1500W surge protection and 15kV electrostatic protection. The multi-mode communication reaches 2km and the multi-mode communication reaches 20km. RS 485 supports 32-point polling.
