GPI IN 1–4
Response
The GPI IN Response 1–4 settings determine what happens when a GPI trigger is
received at the FS2’s GPI Inputs (1–4). A GPI Trigger is defined as a TTL low voltage
level (0 to 0.8V with respect to its isolated ground pin). The GPI interface pinout and
specifications are discussed in
Appendix B: GPI & RS422 Pinouts” on page 199.
Input video sources selected by GPI trigger remain selected until the trigger is
released. GPI Inputs light the front panel EXT LED when triggered.
