The following topics describe the modes of module operation.
Auto-Poll Disabled Mode
If the auto-polling feature is disabled (Auto-Poll Code = N), the module functions as
shown in the following diagram:
Only the user commands are executed and all data is placed in and sourced from the
module's internal database. The user is responsible for constructing all commands to
control and monitor the instruments attached to the channel.
