The RS485 interface is used in many applications in industrial and home automation (e.g. MODBUS), lighting control (DMX), video surveillance (Pelco D) etc. use. There are also some RS485 extensions for the Arduino. Unfortunately, these are mostly unsuitable for professional use, as there is no galvanic separation between the Arduino and the RS485 bus. This may cause malfunctions or damage to the Arduino.

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

RS485 Mode (semi-duplex)
RS422 mode (full duplex)
galvanic separation between Arduino and connected RS485 bus
TX-Pin can be freely selected from the 0-5 Pins via Jumper
RX-Pin can be freely selected from the 0-5 pins via Jumper
adjustable automatic transmitter switch in RS485 mode
adjustable control of the transmitter connection via Pin 6 or 7
switchable pull-up, pull-down and end resistors
RX and TX LEDs to display UART activity
Connection of the bus via pluggable screw clamp
various settings via DIP switches
