Current
. This provides live information about the current value of the exposure
time, gain, and calculated luminance value. Software polling automatically
refreshes the values. A green indicator means the exposure or gain is within
limits. A red indicator means the exposure or gain has reached maximum limits.
3.6 I/O Control
HD video signals have high data rates and the potential for timing jitter. Tri-level
sync (genlock) resolves this potential issue by locking the HD video signals
between the camera and the display monitor.
The I/O control screen lets you enable genlock mode when connected to an
external tri-level sync generator. The format resolution, scan rate, and MHz
settings you select for the genlock device automatically populate the I/O Control
screen. Be sure to align genlock device settings with your current camera.

3.7 Strobe Control
The strobe output screen enables synchronizing two external light sources
(strobes) with the camera timing. This helps maximize camera efficiency in low-
level lighting conditions.
