Description
of the LabMaster DPCI MiniJack 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 complement of MiniJack connections to the DeskTop unit.
The DeskTop unit has MiniJack connections for the following signals:
- Analog Input
- 16 signals, Ain 0 to Ain 15
- Can operate as Single-Ended or Differential Pairs (0-8, 1-9,
2-10, ..7-15)
- Unused Analog Inputs are Automatically grounded!
- This auto-grounding feature makes for a more quiet measuring
system
- Analog Output
- 2 signals, Aout 0 and Aout 1
- Digital I/O
- 16 signals
- Digital I/O Port A, 8 bits
- Digital I/O Port B, 8 bits
- Expansion Signals
- 2 signals - which can be used for two additional connections
A light on the front of the DeskTop Unit illuminates to indicate the
presence of power.
All of the data acquisition circuits 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 MiniJack DeskTop unit:
The DeskTop unit is about 11" wide x 7" deep x 4" high (280mm x 180mm x
100 mm). The front of the DeskTop unit has 36 MiniJack
connections.

Inside the DeskTop unit are the various electrical circuits along with
some switch and jumper positions that are used to customize 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. Depending on your
application and if you had the system pre-configured by Scientific
Solutions you may or may not have to access the inside of the
unit. Pre-configured systems normally do not have to be accesssed.
The Back of the DeskTop unit has connections for the LabMaster DPCI
PC
Interface and for the power supply. The LabMaster connection is a
DB25 pin connector. The power supply uses a 2.1mm positive center
post connection. The LabMaster DPCI requires a 5v power supply
that is also provided with the unit.

slot. It is approximately 2" x 4" (50mm x 100mm). The card
has a single DB25 socket connector.

Connecting the LabMaster DPCI and the
DeskTop Unit:
- To connect the LabMaster DPCI and the DeskTop Unit, use the
following steps:
- Install the LabMaster DPCI card into your computer
- Attach the power supply (included) to the DeskTop unit.
- Notice that with the power supply connected the front panel
light does not illuminate (not yet!).
- Connect the cable (also included) between the LabMaster DPCI card
installed in the computer and the DeskTop unit.
- Turn the power ON to your computer.
- Now note that the front panel light of the DeskTop Unit is
illuminated. The DeskTop unit requires both the power supply to
be connected AND the computer to be on in order to provide power to its
internal circuits. The DeskTop unit automatically powers on when
the
computer is on and turns off when the computer is off.
- Connect your signal connections as needed
