Industrial USB to RS485 bidirectional converter with original FT232RNL and SP485EEN chip. Due to its stable communication, it is an ideal choice for industrial control equipments and/or applications with high communication requirement.
Onboard original FT232RNL and SP485EEN chips, providing better stability and compatibility, built-in lightningproof tube, resettable fuse, ESD and TVS protection circuits, etc.
The USB signal can be converted into a balanced differential RS485 signal and the transmission rate is stable. The reliable speed is 300-921600bps, the transmission distance is about 1.2km for RS485, and about 5 meters for USB.
Supports Mac, Linux, Android, WinCE, Win11/10/8.1/8/7/XP, etc.
Onboard 3 LEDs for indicating the power and transceiver status
