All of the data acquisition cirucits A/D, D/A, Digital I/O , Counter/Timer are external to the computer and are controlled by the LabMaster DPCI card in the computer using a single quick-connect round cable.  The LabMaster DPCI is 100% register level compatible to the original PC LabMaster product introduced in 1981.

Inside the DeskTop unit are the various electrical circuits along with some switch and jumper positions that are used to customized the unit for particular software.  To access the inside, clips in the four corners of the top are "popped off" with a small flat-bladed screw driver.  Under each clip is a philips screw that is also removed.  Be sure to save and not loose the screws as they are metric thread and difficult to replace.
