Support USB to RS485 bidirectional conversion
Fast communication, stable and reliable, better compatibility
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
3 LEDs for indicating the power and transceiver status
