Industrial USB to RS485 Bidirectional Converter Onboard CH343G Chip Multi-Protection Circuits 300bps-3Mbps Baudrate Support Linux Android Wince Win10/8.1/8/7/XP Up to 1.2km Transmission Distance

Industrial USB TO RS485 Bidirectional Converter Onboard original CH343G Multi-Protection Circuits.
Onboard Original Chips: Onboard original CH343G and SP485EEN chips providing better stability and compatibility built-in lightningproof tube resettable fuse ESD and TVS protection circuits etc. Onboard TVS (Transient Voltage Suppressor) effectively suppress surge voltage and transient spike voltage in the circuit lightningproof & anti-electrostatic. Onboard resettable fuse and protection diodes ensures the current/voltage stable outputs provides over-current/over-voltage proof improves shock resistance. Transmission distance up to 1.2 km: The USB signal can be converted into a balanced differential RS485 signal and the transmission rate is stable. The reliable speed is 300bps ~ 3Mbps the transmission distance is about 1.2 km for RS485 and about 5 meters for USB.
Multi system Support: Linux Android WinCE Win11/10/ 8.1 /8/7/XP etc.
