This product is a USB to RS232/RS485 converter. It allows you to connect the USB interface of a computer or other device to an RS232 or RS485 logic-level device for data communication. The 2-meter cable ensures stable transmission and is compatible with multiple devices and operating systems. It features an onboard power supply and signal indicators, as well as support for 3.3V/5V level switching and RS232/RS485 communication. The built-in self-recovery fuse, ESD protection, and IO protection diodes provide added durability and reliability.
Features
- Adopts the original FT232RNL chip solution, it ensures high-speed communication that is stable, reliable and compatible
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, anti-electrostatic
- Onboard resettable fuse and ESD to prevent overcurrent, overvoltage, backflow and static electricity, enhancing shock resistance and ensuring stable and secure communication
- Onboard RS232/485 communication switching circuit, allows users to flexibly switch communication types by toggling the switch
- Onboard RS485 output terminal with a 120R resistor, which can be enabled by a toggle switch for flexible switching
- Onboard 3 LED indicators for easy monitoring of power and signal transmission status
- ABS environmental-friendly case, compact in size, portable and easy to use, cost-effective
