Hi, Does anyone one know the purpose of the big green daughter board that is on most all crrent NMC's? The reason I ask is that we found and older NMC, and this one does not have the board on it. What is it, and what does it do? Thanks in advance, Rick - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
