The RS485 Shield for Arduino has not been identified with the letter A & B to make the connection.
RS485 Shield for Arduino
Posted 18 April 2014 - 01:21 AM
The incorporation of rs485 shield is to connect two arduinos UNO using it in long distance as master/slave configuration.
The first question is if definitively the shields can be used for this application?
The second one is if I need two shields, one on each arduino UNO to transfer the inputs/outputs data through two cables connection? This question was made to buy another shield asap.
Third question is what cable do you recommend to make the connection between rs485 shields?
If you have any additional recommendation for this application does not hesitate in send it.

Seeing in your learning center I found this tutorial, http://learn.linkspr...-v2-on-arduino/
It seems similar.
In the tutorial appears a rs485 v2, but is not available to buy it.
Let me know.
Please do not forget me... I'm wating for you to know about the tutorial and the version 2 of the rs485 shield to buy another arduino and another rs485 shield to combine it or buy 1 UNO with 2 new v2 shields of the rs485.
Please tel me know.

I used RS485 shield to communicate for Arduino.
Code for the transmitter:

How can I receive multiple inputs in the receiver from multiple sensors in the transmitter.
I don't know how to do that.

You can just revise the Code for the transmitter. For example:
