Due to the use of photoelectric isolation technology, the electrical and ground circuits of the RS-232 equipment at both ends are completely isolated, thereby protecting the communication equipment from interference and damage from the power ground circuit and surges, significantly improving the reliability and stability of the communication system. At the same time, by changing the original RS-232 interface single ended transmission method and using dual line balanced transmission, the communication distance is greatly increased.
