  • Convert standard RS232 into four independent RS485 channels, expand the connection capacity of RS485 and the number of equipment, save RS232-RS485 converter, and avoid the instability caused by serial power theft; Connect one RS485 input cable to the main RS485 port and expand it into four independent RS485 ports to improve the communication capability of the RS485 port, increase the number of connected devices, and extend the communication distance. (This is convenient for tree networking.)

    Applicable Place:
    RS485 industrial bus networking of various weak current systems, a large number of equipment, high requirements for network stability, wiring requirements of standard occasions.
