Feature

Adopt photoelectric isolation technology to isolate the electrical and ground circuits of both RS-232 devices, which protects the communication equipment from the disturbance of power supply grounding circuit and surge, obviously improves the reliability and stability of the communication system.
Uses double-line balanced transmission, the original single-end transmission mode of RS-232 interface is changed, greatly enlarges the communication distance.
There are 4,6 and 8 lines for power supply. Four lines can transmit a pair of data signals. Six lines and eight lines can also transmit a pair or two pairs of control signals.
Small size, no special requirements for conductor wires, no external power supply required, plug and play, convenient to use.
Widely used in point-to-point RS-232 communication, multi-user terminal and host connection, RS-232 remote control system, program-controlled switch billing terminal and satellite receiver.
