EXTRA INFORMATION
Entering the Threshold data:
At present the threshold values have to be entered as a count between 0 and 255, (8bit word), e.g. on
a -5VDC to 32 VDC system:
COUNTS = (( VOLTAGE + 5 ) / 37) * 255
16 V would be represented by:
(16+5)/37 = 0.567.
0.567 * 255 = 145 counts
0VDC would be represented by:
(0+5)/37 = 0.135
0.135 * 255 = 34 counts
