Most of above card come both with a screw-terminal and D connector breakout. You generally want to use the D connectors - a large pile of spares are in the drawers on your right.
You can use this unit in many ways. First it is basically is a robust relay/IO system (and as you can verify a relay setting; it won't lose them across powercuts and is autonomous from the PC/laptop controlling - it is generally more suitable for controlling the more dangerous things - such as a climate chamber left on overnight). Secondly - as it understands GPIB one can use the matrix or the relay cards to measure many values in quick succession - with the HP3488A going to the next value on completion of the metering (as it follows the action on the GPIB bus).
If someone is interested in linking Dirk's unit to other GPIB equipment to make additional measurements, let me know - I have some devices such as DACs, ADCs, switches and various bits of test gear I can lend. --Artag 18:36, 7 April 2011 (UTC)
