Industrial USB TO RS485 4-CHConverter, Extending USB to 4CH RS485, allows concurrent and independent communication for each channel.
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. Onboard RS485 output terminal 120R resistors, enabled/disabled via DIP switch.
Compatible with Mac OS, Linux, Windows 11 / 10 / 8.1 / 8 / 7, Android.
Transmission distance up to 1.2km: The USB signal can be converted into 4 balanced differential RS485 signals and the transmission rate is stable. The reliable speed is 1200~460800bps, the transmission distance is about 1.2km for RS485, and about 5 meters for USB.
