Chun = integer variable containing a channel number. For A/D frames, use Chan in
the range of 0 to topchannel, where topchannel

comments
KSetStartStopChn is used to specify a range of channels for KSyncStart or
KIntStart operations. For instance, several A/D channels
may
be monitored
sequentially by specifying independent Start and Stop Channels. If StartChn
=
2
and StopChn
= 4,
then samples will be taken from Channels
2,3,4.
KSetChn may be used to reset the start channel number after KSetStartStopChn
has established a channel range.
