Digital I/O port and TSP-Link synchronization lines
Each module of the 2606B has two sets of hardware lines that can be used for triggering: 14 digital
I/O lines and three TSP-Link
®
synchronization lines. These trigger objects can be configured and
controlled in the same way.
See Digital I/O (on page 3-78) for more information about connections and direct control of the digital
I/O and TSP-Link synchronization lines.
Mode
Indicates the type of edge the hardware lines detect as an external input trigger. Mode also indicates
the type of signal generated as an external output trigger. The following table describes the hardware
trigger modes for the hardware trigger lines. The hardware trigger modes are described in more detail
in
Hardware trigger modes (on page 3-54).
To disable triggering on the hardware trigger lines, set the mode to bypass. This allows direct control
of the line.
Hardware trigger mode summary
Trigger mode Output Input
Unasserted Asserted Detects
Bypass N/A N/A N/A
Either Edge High Low Either
Falling Edge High Low Falling
Rising Edge The programmed state of the line determines if the
behavior is similar to RisingA or RisingM:

High similar to RisingA

Low similar to RisingM
RisingA High Low Rising
RisingM Low High None
Synchronous High latching Low Falling
SynchronousA High latching High Falling
SynchronousM High Low Rising
Pulsewidth
Specifies the pulse width of the output trigger signal when the hardware line is asserted.
