4.1.5 Negation of Data Bit D11 (J300)<br />
Via jumper field J300 the data bit D11 can be inverted for all D/A-converters simultaneously. This is<br />
necessary, because depending on the mode of the output voltage, the D/A-converters expect the data<br />
in various formats:<br />
16<br />
In unipolar operation the data has to be transmitted in USB (Unipolar Straight Binary)<br />
format.<br />
In bipolar operation the converter expects the data in BTC (Binary Two's Complement)<br />
format.<br />
Attention:<br />
The negation is especially important, because the analog outputs will only be set to 0 V after a<br />
RESET, if bit D11 has got the level required for the operating mode!<br />
