Max & Min FPS
Camera maximum FPS can be reached at default CoaXPress configuration. If you reduce CoaXPress speed (ex:
CXP6 to CXP5 or CXP3), the maximum FPS is reduced.

Max & Min Exposure Time
The maximum exposure time depends on current frame rate and can be calculated using this formula:
𝑴𝒊𝒏_𝑬𝒙𝒑𝒐𝒔𝒖𝒓𝒆 = 𝟐µ𝒔
𝑴𝒂𝒙_𝑬𝒙𝒑𝒐𝒔𝒖𝒓𝒆 =
𝟏
𝑭𝒓𝒂𝒎𝒆𝒓𝒂𝒕𝒆
− 𝑴𝒊𝒏_𝑬𝒙𝒑𝒐𝒔𝒖𝒓𝒆

Sync Out Output
The camera output Sync Out delivers a TTL signal reflecting camera frame acquisition. External
synchronization may be operated in level detection mode. Please see the external synchronization timing for
more information about resulting frame rates and exposure times.
The Sync Out output can be used to synchronize other devices as e.g. additional cameras or external light
flashes.
Using camera accessory “Pigtail cable” (BNC adapter) is the easiest way to use Sync Out signal.
Note that:
•
Sync Out signal period is the real effective frame delivered by the camera.
•
Sync Out signal high time is the effective exposure time done by the camera.
