The Star shifting interface converter products include three major series:
Industrial serial optical fiber converter can convert the industrial site RS232/485/422 serial electrical signal into optical fiber signal transmission, to achieve long-distance transmission requirements, improve signal anti-interference ability;
Industrial serial cable converter, to achieve the industrial site RS232 and RS485/422 signals between the conversion, as well as multiple serial bus concentrator function, provide active/passive, isolated/non-isolated and other types of choice;
Industrial serial port repeater can realize the isolation relay function of RS232/485/422 signal in industrial field. By isolating and amplifies the signal, it can extend the communication distance and anti-interference.
● Port powered, no need external power supply
● Particular protecting circuit for the serial port, hot-swappable
● Automatically transmit with no delay, no need CTS flow control
