comments
For certain A/D acquisition modes, the user can specify different gains for different
input channels using a channel/gain array. This array is passed to the driver using
KSetChnGAry. For the driver to accept this array, it must be in specific format; this
format is not achievable directly from BASIC.
m o r m a t c b n G A r y
operates on the array that is actually passed to your BASIC
program, making it unreadable. To restore the array so that
it
is readable from
BASIC, use the complementary function KRestoreChnGAry.
