Features At A Glance

• 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
• Aluminium alloy case with oxidation dull-polish surface, CNC process opening, solid and durable, TYPEIndustrial Grade USB to RS485 converterHOST PORTUSBDEVICE PORTRS485BAUDRATE1200bps ~ 460800bpsUSBOperating voltage5VConnectorUSB-BProtection500mA resettable fuse, ESD protectionTransmission distanceAbout 5mRS485ConnectorScrew terminalProtection600W lightningproof and surge-suppress, 15KV ESD protectionTransmission distanceMaximum communication distance is about 1200m (at a low rate, with 120R resistor turned on)Transmission modePoint-to-multipoints (up to 32 nodes, it is recommended to use repeaters for 16 nodes or more)OPERATING ENVIRONMENTTemperature-40 ~ 85℃Humidity5%RH ~ 95%RHOPERATING SYSTEMWin7/8/8.1/10/11, Mac, Linux, Android
