If you are serious about Register Based programming you must be a glutton for punishment. 🙂
There are a few standard registers in VXI that tell you the manufacturer's ID code, and the model, etc., but beyond that the registers are defined by the manufacturer. A poke of a value to a register of one card may set a voltage range, the same register on another card may set a switch or be illegal. You need the manufacturer's programming guide to tell.
But each register does something. You may poke values to it, or peek values from it. The register may be 1-byte, 2-bytes, 4-bytes (etc) wide, and may represent integer, real or string data - again defined by the manufacturer for that card.
What NI slot0 card are you using? What other manufacture
r's cards? If it's an NI MXI-2 slot0 and Agilent register based cards, there may be Plug&Play drivers available. This gets you passed the Register Based programming and lets you program at a higher level.
