Description of the LabMaster DMA Screw Terminal Product
The LabMaster DPCI product consists of two cards; The LabMaster DPCI PC Interface which is installed inside the computer, and the LabMaster DPCI External card which is housed in a DeskTop unit away from any internal computer noise.  In this configuration we have also added a full custom screw terminal inside the DeskTop unit.

The DeskTop unit has a screw terminal pair (signal and ground) for every LabMaster DPCI signal including:

A light on the front of the DeskTop Unit illuminates to indicate the presence of power.

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.

LabMaster DPCI Screw Terminal DeskTop unit:
The DeskTop unit is about 11" wide x 7" deep x 2" high (280mm x 180mm x 50 mm).  The front of the DeskTop unit has slots for signal wires.

Inside the DeskTop unit is a full screw terminal.  To access the screw terminal, 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.

There are two cards inside the unit, the LabMaster DPCI External Card and the Screw Terminal card.  These two cards are connected with ribbon cables, so when the top is lifted off it is best to place it behind the unit.  Try to keep the front and back panels on the bottom piece and fold the top over towards the back.
