The board has a triple rs422 interface, a rs485 interface and 3 opto-ouputs. It also has a dip switch to set id number.

The design is based on RBBB and Duemilanove boards. Instead of build a shield for duemilanove I will build a complete microcontroller board. I need a triple rs422 receiver to connect with a encoder. I will use a MAX3097. I will use RS485 and Modbus communications with Mango M2M. I need 3 opto-outputs and the possibility of manual activation (on-board switches)

Any suggestion will be welcome.
