Overview

The Multibus 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 equipment and/or applications with high communication requirements.

Feature

  • 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 jam proof, low power consumption
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic
  • Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
  • 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

Note
A pad for 120R terminal resistor is reserved for the RS485 port, users can add the resistor to the begin/terminal devices if connect multiple devices.

Install driver

Generally, after connecting to the computer, the system will automatically prompt to install the driver. If the device cannot communicate normally after connecting to the device, And if the device has a yellow exclamation mark in the device manager, you need to manually install the driver.

  • Download the Driver
  • unzip the driver and double-click the exe file to install the driver.

 Answer:
Not supported, A side can only communicate with B side, B side can only communicate with A side

 Answer:
It can be powered through the TTL power interface on the A side, the USB-B data line interface, and the PWR power supply (outer diameter 5.5 inner diameters 2.1) interface, and you can choose one of the three; the power supply voltage is 5V. When the PWR power interface is selected for power supply, the TTL power interface of the A end can supply power to the outside
