Description
USB TO RS232/485/TTL
Stable Transmission | Multi-Device Application | Multi-OS Compatibility
- Adopts original FT232RNL or CH343G, fast communication, stable and reliable, better compatibility
- Onboard unibody power isolation, provides stable isolated voltage, doesn't require extra power supply for the isolated terminal
- Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, anti-lightning & anti-ESD
- Onboard self-recovery fuse and protection diodes, provides stable current/voltage outputs, provides over-current/over-voltage protection, improves shock resistance
- Fully automatic transceiver circuit with no delay, ensures fast and stable communication between the USB port and different interfaces without interfering with each other
- Onboard TTL serial 3.3V/5V voltage translator, configures the TTL level via switch
- Aluminum alloy enclosure with sandblasting and anodic oxidation, CNC process, solid and durable
- 3 LED indicators for power and transceiver status
- High quality USB-B and RS232 connectors, smooth plug/unplug

Original Industrial-Grade Chip
Built-in original FT232 or CH343 chip
Fast communication, stable and reliable, better compatibility
Safer Isolated Design
- Onboard unibody power isolation, provides stable isolated voltage, doesn't require extra power supply for the isolated terminal
- Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
Multi-Protocol & Multi-Type Conversion
USB TO RS232, RS485 or TTL(UART)
RS232, RS485 or TTL(UART) TO USB
* Only one of RS232, RS485 and TTL can be converted to USB at the same time; RS232, RS485 and TTL cannot be converted to each other
Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, anti-lightning & anti-ESD. Onboard self-recovery fuse and protection diodes, provides stable current/voltage outputs, provides over-current/over-voltage protection, improves shock resistance.
Supports Mac, Linux, Android, Windows 11 / 10 / 8.1 / 8 / 7 and more.
