ComTec GmbH 2-3
Extra Power Supply Connector
The 'Extra Power Cable' is necessary if any MPA-3 Quad ADC Port Module is connected with the
Base Module and is usually delivered with systems containing such a module. Find an available
mounting place on the rear of your PC. Mount the slot bracket with 9 pin female D-SUB connector
and plug in the floppy type power connector.
MPA-3 BASE Module
Find an appropriate place to set up your MPA-3 modules. This place should comply to a standard
laboratory environment. It should be dry, not exposed to direct sun shine and it should be at room
temperature.
Consider that the cable length of the ADC connections is limited to 1m. Thus, the MPA-3 modules
should be located near the ADCs.
If you not only purchased a MPA-3 BASE module but also one or more MPA-3 Quad ADC Port
modules take into account that it might be appropriate to have the BASE module as the top one in
the tower of MPA-3 modules because the auxiliary BNC connectors are better accessible and the
LED indicators are better visible. Also, the assignment of module numbers by default starts at the
BASE module and thus, the numbering of the ADC ports will be from the left top to the right
bottom (ref. Figure 1.1).
Now connect the BASE module and the PCI card using the 37 pin D-SUB connector cable (FHS
Link cable) supplied. The standard cable supplied is two meters in length but up to ten meter
