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 equipments and/or applications with high communication requirement. NOTE: only one pair of devices will be matched for a complete communication between the Group A and Group B terminals at the same time  

Useful link:

USB/RS232/RS485/TTL Converter

Features:

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

Packages Includes:

1 x Waveshare Industrial Isolated Multi-Bus Converter, USB / RS232 / RS485 / TTL Communication

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
