3.5 D/A Converter Outputs
The two D/A converter outputs are buffered and scaled to provide an output from 0 V to
+10 V (12-bit resolution) or ±10 V (11-bit resolution, one bit used for polarity). The selec-
tion is made via jumpers on header JP3 for AOUT0 and via JP6 for AOUT1. There is also
the option to select either D/A converter output as a 4–20 mA current output via jumpers
on header JP5. Figure 17 shows the D/A converter outputs.
Figure 17. D/A Converter Outputs
Table 9 summarizes the jumper settings to configure each D/A converter output. Note that
the software configuration requires both channels to be configured the same way.
