Communication between different buses

Features At A Glance

The USB/RS232/RS485/TTL Converter is an industrial grade isolated converter that supports USB / RS232 / TTL to RS232 / 485 / TTL, with built-in power supply isolation, digital isolation, and protection circuits like TVS diode. It is easy to use and suitable for industrial control equipments and/or applications with high communication requirement.

  • Adopts original FT232RL for USB communication, fast communicating, stable and reliable, better compatibility
  • Onboard over-voltage, over-current protection circuits (there's no protection between the two power supplies of the host terminal)
  • Onboard unibody power supply isolation, providing stable isolated voltage, no extra power supply required for the isolated terminal
  • Onboard unibody digital isolation, for isolating the signal, reliable and jamproof, low power consumption
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
  • Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
  • Onboard TTL serial port 3.3V and 5V voltage level switch, allows the user to select TTL level of the Group B terminal
  • Aluminium alloy enclosure with oxidation dull-polish surface, solid and durable

Interface introduction
Multi-protocol Multi-bus conversion

Transmitting data from Group A terminals to Group B

Transmitting data from Group B terminals to Group A

  • Terminals in the same group cannot communicate with each other.
  • Terminals in the same group cannot send data at the same time, while concurrently receiving is allowed.
