Product Features

• Supports USB to RS485 bidirectional conversion
• Onboard original FT232RNL chip, enabling high-speed, stable, and reliable communication with excellent compatibility
• Onboard isolated transceiver, integrated electrical isolation and ESD protection, effectively improving communication stability and anti-interference capabilities in industrial environments
• Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
• Onboard resettable fuses and protection diodes ensure stable current/voltage outputs, provide over-current/over-voltage protection, improves shock proof performance
• Onboard 3 LEDs for indicating the power and transceiver status

The USB signal can be converted into a balanced differential RS485 signal, and the transmission rate is stable. The reliable speed is 300bps ~ 512000bps, the transmission distance is about 1.2km for RS485, and about 5 meters for USB
