Help with a 1756-DHRIO Module.

Last week I had my first trouble with out RIO set up. Ive never really dealt with these cards, and it made me question something.

Do the selector switches on the module have to match how you set the card up in RSLogix5000, or does it just use one over the other ?

The selector switches do need to be setup to configure CHA and CHB function, i.e., RIO, DH+ and the baud. The other switches will set the node address the module will assume on the RIO network. Then you will add your ASB modules or whatever your communicating to in the I/O based on Rack size and Baud. You may some luck over here with this too.
