Description
Industrial Isolated Multi-Bus Converter, USB / RS232 / RS485 / TTL Communication
Communication between different buses
The USB/RS232/RS485/TTL converter is an industrial-grade isolated converter that supports USB / RS232 / TTL to RS232 / 485 / TTL conversion. The device features built-in power isolation, digital isolation, and protection circuits such as a TVS diode. It is easy to use and suitable for industrial control equipment and applications with high demands for communication stability.
- Uses original FT232RL chip for USB communication: fast, stable, reliable, and excellent compatibility.
- Built-in overvoltage and overcurrent protection circuits.
- Built-in full power isolation: provides stable isolated voltage, no need for additional power supply for the isolated terminal.
- Built-in digital signal isolation: reliable, interference-resistant, with low power consumption.
- Built-in TVS (Transient Voltage Suppressor): effectively suppresses surge voltages and transient spikes in the circuit, provides lightning and electrostatic protection.
- Built-in resettable fuses and protective diodes: ensure stable output current and voltage, protect against overloads, and improve surge resistance.
- TTL voltage level switch (3.3V and 5V) for Group B port: allows the user to select the desired logic level.
- Aluminum alloy casing with oxidized matte finish: durable, long-lasting, and aesthetically pleasing.

Data transmission from Group A terminals to Group B
Data transmission from Group B terminals to Group A
- Terminals within the same group cannot communicate with each other.
- Terminals within the same group cannot send data simultaneously, but simultaneous reception is allowed.
Three LED indicators for quick power and signal transmission/reception status check:
The aluminum alloy casing with an oxidized matte finish provides durability, longevity, and a professional appearance.
