Details
When
channel.connectsequential
is enabled, the list of channel actions is acted on
sequentially. No two relays are opened or closed simultaneously.
Using a sequential close allows you to determine the time for a close operation to happen. For
example, if you close three channels and each takes 4 ms to closej (assuming no additional user
delay times), with sequential on, it will take 12 ms. With sequential off, it may be 4, 8 or 12 ms,
depending on whether or not the card can close multiple channels at once.
The order in which channels are opened or closed is not guaranteed with sequential off.
The sequential setting affects all channels in the instrument.
Example
channel.connectsequential = channel.ON
Specifies that channels close sequentially.
