<p>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.</p> <p>Onboard unibody power supply isolation, provides stable isolated voltage. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption.</p> <p>Onboard (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof \u0026 ESD protection. Onboard self-recovery fuse and protection diodes, the current\/voltage stable outputs, provide over-current\/over-voltage proof, improve shock proof performance.</p> <p>Onboard power supply screw terminal, allows 5V~36V DC wide range input.</p> <p>9 LEDs for indicating the power and transceiver status, Aluminum alloy enclosure with sand blasting and anodic oxidation, solid and .</p> <p>Specifications:</p> <p>HOST PORT: USB</p> <p>DEVICE PORT: RS232</p> <p>BAUD RATE: 300bps ~ 921600bps</p> <p>: forMacOS,Linux,Android, 11\/10\/8.1\/8\/7</p> <p>USB interface:</p> <p>Operating voltage: 5V</p> <p>Connector: USB-B</p> <p>Protection: 200mA self-recovery fuse, isolated output</p> <p>Transmission distance: about 5m</p> <p>POWER SUPPLY INTERFACE:</p> <p>Power supply: 5~36V DC screw terminal</p> <p>Protection: Anti-reverse</p> <p>ISOLATED RS232:</p> <p>Protection: diode, surge protection \u0026 ESD protection, power isolation and signal isolation</p> <p>Transmission mode: Point-to-point</p> <p>Transmission distance: about 15m</p> <p>INDICATORS:</p> <p>PWR: Red power indicator, lights up when there is USB connection and voltage is detected</p> <p>TXD1~4: Green TX indicator, blinking when the RS232 port is sending data</p> <p>RXD1~4: Blue RX indicator, blinking when the RS232 port is receiving data</p> <p>Temperature range: -40 ~ 85Humidity range: 5%RH~95%RH</p> <p>Port: Male Port</p> <p>Material: Aluminum alloy</p> <p>colour: black</p> <p>Package Contents:</p> <p>1 x converter</p> <p>1 adapter</p> <p>1 x USB cable</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
