16.2.9 Logic Out
This is a standard female BNC connector.
0 to +3.3V
DC
programmable logic level output (TTL-compatible.) The output can be
programmed via software as one of the following signals:
• ACQUIRING;
• IMAGE SHIFT;
• LOGIC 1;
• READ OUT;
• SHUTTER;
• WAIT FOR TRIGGER.
For detailed information about each of these signals, refer to
Section 5.12, Logic Out Control, on page 84.
When the
Invert LOGIC check box is checked, the output is at a logic low when the action is
occurring.
16.2.10 Mon RF Out [PI-MAX4: 1024i-RF only]
This is a standard female BNC connector. Provides an approximate indicator of the
user-defined RF applied to the photocathode.
16.2.11 Monitor
This is a standard female BNC connector. This TTL signal is used to monitor actual gate
timing.
The TTL logic 1 pulse is delayed ±3 ns with respect to photocathode gating.
Cable delay, ~1.5 ns/ft, is in addition to the delay at the
connector.
16.2.12 Power Connector
7-pin D specialty connector. Connects to the standard PI-MAX4 power supply. See
Figure 16-1.
16.2.13 Ready Out
This is a standard female BNC connector. This normally LOW TTL signal indicates the
camera status. It changes state upon the completion of cleaning cycles prior to an exposure.
