Feature:
1. Electric isolation technology is used to isolate electrical and ground circuits of two RS-232 devices
2. The protects the communication device from the interference and overload of the power-off circuit, which significantly improves the reliability and stability of the communication system
3. Using double-line balance transmission, the original RS-232 interface single-ended transmission mode is increased, and the communication distance is added
4. The size of the small size requires no special requirements for non-external leads, and the use is convenient
5. Widely used in RS‑232 point‑to‑point communication, multi‑user terminals and host connections, RS‑232 remote control systems, billing terminal controls switch
