Description
Industrial isolated USB to RS232/485/TTL interface converter
Industrial isolated USB converter. Stable data transmission | Compatible with various devices | Support for many OS.
This product is an industrial isolated USB to RS232/485/TTL converter, equipped with the original CH343G chip. It provides fast communication, stability, reliability and better compatibility. The device comes in an aluminum alloy case, which makes it sturdy and durable.
Aluminum alloy housing, USB-B port, RS232 DB9 port, screw terminals for RS485/TTL and LED indicators
Key features
- Uses the original CH343G chip for fast, stable and reliable communication with improved compatibility.
- Built-in galvanic power isolation provides stable isolated voltage and does not require an additional power source for the isolated side.
- Built-in digital (ADI magnetic) isolation for signals ensures high reliability, strong noise immunity, and low power consumption.
- The built-in TVS (transient voltage suppressor) effectively suppresses surges and transient peak voltages in the circuit, providing protection against lightning and electrostatic discharge.
- The built-in self-recovering fuse and protection diodes provide stable output currents/voltages, over-current/voltage protection, and improve shock resistance.
- The fully automatic, zero-delay transceiver circuit ensures fast and stable data exchange between the USB port and various interfaces without mutual interference.
- The built-in 3.3V/5V TTL level converter allows you to adjust the TTL level using a switch.
- The aluminum alloy body with sandblasting and anodic oxidation is CNC machined, making it strong and durable.
- 3 LEDs to indicate power and transceiver status (PWR, TXD, RXD).
- High-quality USB-B and RS232 (DB9 male) connectors for easy connection and disconnection.
- Support for various operating systems: Mac, Linux, Android, Windows 11 / 10 / 8.1 / 8 / 7.
Important note:
- Only one of the interfaces (RS232, RS485 or TTL) can be converted to USB at a time.
- RS232, RS485 and TTL interfaces cannot be converted into each other using this device.
