Product Description

The RS485 interface is in many applications in industrial and home automation (e.g. modbus), lighting control (DMX), video surveillance (Pelco d) and much more. used. There are already some RS485 extensions for the Arduino. Unfortunately, these are usually unsuitable for professional use, since a galvanic separation between the Arduino and the RS485 bus is missing. This can lead to malfunctions or damage to the Arduino.

Our Shield does not have these disadvantages and comes with the following functions:

  • RS485 mode (half -duplex)
  • RS422 mode (full duplex)
  • Galvanic separation between Arduino and the connected RS485 bus
  • TX-PIN can be chosen freely from pins 0-5 via jumper
  • RX-PIN can be chosen freely from pins 0-5 via jumper
  • Adjustable automatic transmitter connection in the RS485 mode
  • Adjustable control of the transmitter connection via pin 6 or 7
  • Switch-on pull-up, pull-down and final resistors
  • RX and TX LEDs to display the activity of the UART
  • Connection of the bus via plug -in screw clamp
  • Various setting options via DIP switches
  • Stackable header
