LabMaster ^® DPCI BNC Connections

LabMaster DPCI interface card shown with DeskTop BNC (Front View showing the BNC connections)

Description of the LabMaster DPCI DeskTop BNC Product
The LabMaster DPCI product consists of two cards; The LabMaster DPCI computer 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 added a full complement of BNC connections on the DeskTop unit.

The DeskTop BNC provides convenient industry standard BNC connections for the LabMaster signals in a small compact desktop unit measuring only 11" wide by 6" high by 7" deep (280mm x 152mm x 178mm).

BNC connections are ideal for many applications. They are widely used and standard patch cables are easily obtained. They are rugged, yet easy to use and stay connected with the "twist-on" locking feature of the connector.

A single quick-connect round cable connects from the LabMaster DPCI Interface to the LabMaster DeskTop BNC Unit, replacing the traditional ribbon cable connections.

Back of the LabMaster Desktop BNC Unit:

The Back of the DeskTop unit has connections for the LabMaster DPCI Interface and for the power supply.  The LabMaster connection is a DB25 pin connector.  The power supply uses a positive center post connection.  The LabMaster DPCI requires a 5 volt power supply that is also provided with the 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.
