Comments:
Block length for block transfer write is 00. Unscaled channels have a minimum scaling
value of 0 and a
maximum scaling value of 4095. If channels 1 and 2 were configured for +
10V operation,
then the minimum scaling value would be -4095 and the maximum scaling value would
be +4095. Since channel 3 has a negative minimum scaling value, you must set the polar-
ity bit (bit 10) associated with channel 3’s minimum scaling word in the configuration
word (word 5 of the write block).
