DAC812-Adapter (DAC812-20mA)

9.7 Assignment of Connectors of the DAC812-Adapter

In addition to the 64-pin socket strip P2 the adapter has got a 10-pin post connector (P3) to
connect the analog outputs via flat ribbon cable and it has got screw terminals to connect the
analog supply voltages (P4, P5).

The analog outputs can also be connected via screw-type terminals (such as

PHOENIX

SMKDS1.2-3) (P11-P18). These connectors are not available in the standard version of the
adapter. If required, they can be equipped afterwards by the user or the manufacturer, if desired.

If connectors P11 to P18 are not required, the adapter board can be sawn-off at the line especially
marked. This is useful, if the space in the VMEbus system is limited. The length of the board is
reduced from 132 mm to 81.5 mm. Please refer to figure 5 'Position of jumpers of the DAC812-
adapter' on page 41 for the position of the line.
