3.3.2 External Trigger Signal Input/Event Output Connectors
For the external trigger signal input/event output connector, insert the external trigger signal input/ event output cable
shown in Figure 3.6. The external trigger signal input/event output cable is a 9-pin cable, inputs the external trigger
signal, and outputs the break signal and event signal.
The external trigger signal input/event output signal is input/output at CMOS (LVCC3245) level.
Break signals are held low when the break conditions are satisfied. And, event signals are held high while events 1
through 6 specified as breakpoints are established.
Table 3.4 gives pin assignments of the external trigger signal input/event output connectors.
