SKU: 212-1-1

Industrial grade RS485 to USB converter which can withstand tough working environment. The housing is made of hardened ABS plastic with a reinforced terminal header for easy connection of communication wires.

This RS485 to USB converter is electrically protected against static electricity, high voltage spikes and other dangerous voltage spikes which can damage your equipment or data signaling. This protection is accomplished by four Transient Voltage Suppressors, one for each data line. Automatic send data control is enabled by default so no external flow or handshake control is needed.
