Trigger link
Input and output triggers are received and sent via the rear panel TRIGGER LINK connec-
tor. The trigger link has four lines. At the factory, line #2 is selected for output triggers, and line
#1 is selected for input triggers. These input/output line assignments can be changed from the
CONFIGURE TRIGGER menu. See Configuring triggering later in this section. The connector
pinout is shown in Figure 10-2.

for the TRIGGER LINK event. See Trigger model. The input requires a falling-edge, TTL com-
