Triggering
9-11
External triggering
Input and output triggers are received and sent via the rear panel TRIGGER LINK connector.
The trigger link has six lines. At the factory, line #2 is selected for output triggers and line #1 is
selected for input triggers. These input/output assignments can be changed as previously
explained in this section. The connector pinout is shown in Figure 9-4.
Input trigger requirements
An input trigger is used to satisfy event detection for a trigger model layer that is using the
TLINK control source. The input requires a falling-edge, TTL compatible pulse with the speci-
fications shown in Figure 9-5.
