Features: Adopts FT4232HL chip, fast communicating, stable and reliable, better compatibility. Supports USB to 4-ch isolated RS232, convenient for expanding multiple RS232 industrial serial devices.Onboard unibody power supply isolation, provides stable isolated voltage. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption.Onboard TVS ( ient Voltage Suppressor), effectively suppress surge voltage and ient spike voltage in the circuit, lightningproof & ESD protection. Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, improve shock proof performance.Onboard power supply screw terminal, allows 5V~36V DC wide range input.9 LEDs for indicating the power and ceiver status, Aluminum alloy enclosure with sand blasting and anodic oxidation, solid and durable.Specifications:HOST PORT: USBDEVICE PORT: RS232BAUD RATE: 300bps ~ 921600bpsOPERATING SYSTEM: forMacOS,Linux,Android,Windows 11/10/8.1/8/7USB interface:Operating voltage: 5VConnector: USB-BProtection: 200mA self-recovery fuse, isolated output mission distance: about 5mPOWER SUPPLY INTERFACE:Power supply: 5~36V DC screw terminalProtection: Anti-reverseISOLATED RS232:Protection: TVS diode, surge protection & ESD protection, power isolation and signal isolation mission mode: Point-to-point mission distance: about 15mINDICATORS:PWR: Red power indicator, lights up when there is USB connection and voltage is detectedTXD1~4: Green TX indicator, blinking when the RS232 port is sending dataRXD1~4: Blue RX indicator, blinking when the RS232 port is receiving dataTemperature range: -40 ~ 85Humidity range: 5%RH~95%RHPort: Male Port / Female PortMaterial: Aluminum alloycolour: black Package Contents:1 x converter1 x power adapter1 x USB cableOnly the above package content, other products are not included.Note: Light reflection an
