Feature:1. HIGH PERFORMANCE: Using the original for FT4232HL chip program, high speed telecommunication is stable, reliable, excellent compatibility; support a variety of telecommunication interface conversion: USB to for RS232, USB to for RS485.2. POWER ISOLATION: Onboard integrated power isolation, can provide stable isolation voltage, isolated end without additional power supply; onboard integrated digital isolation, signal isolation, high reliability, strong anti interference, low power consumption.3. ONBOARD TVS: Onboard TVS (Transient Voltage Suppressor), can effectively suppress the surge voltage and transient spike voltage in the circuit, lightning and anti static; Onboard self recovery fuse and guard diode, can ensure the stable output of the current and voltage, prevent overcurrent and overvoltage, and improve the anti shock capability.4. EASY TO USE: Built in for RS485 output termination 120R resistor, can be enabled by a dip switch, flexible switching; external 9 LED indicators, easy to check the power supply, device configuration status and signal transmitting and receiving status.5. EASY TO INSTALL: Industrial grade isolated USB converter adopts industrial grade metal shell, supports wall mounting and rail mounting, sturdy and beautiful, easy to install.Specification:Item Type: USB to for RS485 422 ConverterMaterial: ABSHost Interface: USBDevice Interface: for RS232, for RS485USB Interface: Operating Level 5VInterface Format: USB Type B InterfaceInterface Guard: 200mA Resettable Fuse, Isolated OutputPORT: 1/2 Interface(for RS232 485 Optional)Isolated for RS232: Interface Form: Wiring terminalsInterface Guard: TVS Tube Guard, Surge and Static Guard, Power and Digital IsolationTransmission Mode: Point to PointCommunication Rate: 300bps ~ 921600bpsIsolated for RS485: Interface Format: Wired TerminalsInterface Guard: TVS Tube Guard, Surge and Static Guard, Power and Digital Isolation (120R Balanced Resistor Jumper Cover Enable)Direction Control Hardware Automatically Determines and Controls the Direction of Data Transmission.Transmission Mode: Point to Multiple (Up to 32 Nodes, Repeaters Are Recommended for More Than 16 Nodes)Teleommunication Rate: 300bps ~ 921600bpsPORT 3/4 Interface(Isolated for RS485 Interface):Interface Format: Terminal BlockInterface Guard: TVS Tube Guard, Surge and Static Guard (120R Balanced Resistor Jumper Cover Enable)Direction Control: Hardware Automatically Determines and Controls the Direction of Data Transmission.Transmission Mode:Point to Multiple (Up to 32 Nodes, More Than 16 Nodes Are Recommended to Add Repeaters)Telecommunication Rate: 300bps ~ 921600bpsIndicator Light: PWR: Power Indicator, Access to the USB, Detecting the Voltage Will Light up RedTXD: Transmit Indicator, Green Light When There Is Data Sent from the USB Port.RXD: Receive Indicator, Blue Light When There Is Data Sent Back from the Device Interface.Operating Environment: Temperature Range -15 ~ 70.Humidity Range: 5%RH ~ 95%RHOperating System: for OS X, for Linux, for Android, for Windows 11 10 8.1 8 7.Package List:1 x USB to for RS485 422 Converter1 x Connecting Cable1 x Screwdriver1 x Buckle Note:Manual measurement please allow some error.<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
