Hi
I have 2 modules (carts) that most communicate with each other via some optical device (sending/receiving identity and position). The carts will be placed in front of each other and will not be moved when in place for a long time. The data received from this optical device goes to a micro (slave) which convert it via Modbus protocol and send it to the master. The micro also sends data through this devoices. Can anyone suggest a simple optical device for purchasing that can do this (both sending and receiving)? It should be as simple and cheap as possible.
Tanks in advance
