3.18.2. Outputting External Trigger Signals
With the system, you can externally output trigger signals. Output is performed with the TRIG TTL
OUT connector's dedicated trigger output system provided by the system, and additionally, output
can also be optionally set from the GENERAL OUT connector. External trigger signal output settings
are also made by selecting [SYNC IN/OUT] from the menu and [TRIG TTL] OUT or [GENERAL
OUT] from the submenu.
Signal output is performed from the TRIG TTL OUT connector and the GENERAL OUT connector
explained in section “2.2.7. I/O Port Connector”.
The chart below summarizes the output systems and the signals that can be output.
