Logic
A channel can be triggered by any combination of signals from the eight inputs and/or other
channel outputs. Channel logic determines the combination of signals that triggers the channel.
The diagram below shows the architecture of the Model 725. Note that any inputs and outputs can
trigger a channel without external cabling.
To define when a channel will trigger, open the channel’s Settings screen then click the Logic tab.
This tab only appears for timing modes which respond to logic. You will enter a logic assignment
for the channel in the large white box.
NOTE: Some timing modes do not respond to trigger logic. For example, a channel
set to operate as a clock will continue to run regardless of what happens to its input.
