Features At A Glance
- Support USB to RS485 bidirectional conversion
- Onboard Original FT232RNL and SP485EEN chip. 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 proof performance
- 3 LEDs for indicating the power and transceiver status
- Due to its stable communication, it is an ideal choice for industrial control equipments and/or applications with high communication requirement.
