Line Trigger Input

For line-scan applications using a hardware acquisition line trigger, anyone or some pairs of the system I/O input ports can be selected as the source(s) for the line trigger control circuit of the acquisition channel.

For that usage, use the parameters belonging to the Encoder Control category.

The line trigger signal can be elaborated from one or two external signals provided by one of the following type of devices:

Possible ports assignments for each case

Sourcing device type

Default port(s) assignment
