6.1 Initialisation<br />
Software<br />
The D/A-converter outputs generally do not have to be especially initialized after a RESET signal by<br />
the VMEbus, if the same operating mode was selected for all output channels. In this case a sequence<br />
control on board resets the output voltages to 0.0 V.<br />
In mixed operation (unipolar and bipolar) the reset status for only one operating mode is met, however,<br />
so that the other channels should be reset by the user.<br />
An output voltage at the D/A-converter channel can be generated by writing the data word word-byword<br />
(depending on operating mode) at the corresponding address of the DAC channel.<br />
The following page shows an example program for accesses to the VME-DAC1612 board in realtimemultitasking-standard<br />
language PEARL.<br />
The MODE register can only be read (see chapter ‘Mode Register (J130)’, page 14 ), from which the<br />
user can take information about the configuration of the VME-DAC1612-board in the system.<br />
