AVT GigE Camera and Drivers Features V2.0.0

This document is a master document for all AVT GigE camera models and is NOT camera specific

IrisVideoLevelMax [Integer] R/W

Video-type lenses only. Limits the maximum driving voltage for closing the lens

iris. Typically, this will be 150; however, it may vary depending on the lens ref-

erence voltage. A lower minimum value slows the adjustment time but prevents

excessive overshoot.

IrisVideoLevelMin [Integer] R/W

Video-type lenses only. Limits the minimum driving voltage for opening the

lens iris. A higher minimum value slows the adjustment time but prevents

excessive overshoot.

LensDCIris

DC-Iris lenses only.

LensDCDriveStrength [Integer] R/W

Lens drive voltage. Altering this changes the speed at which a DC-Iris lens oper-

ates. The lower the value, the slower the lens operates. A higher value may

result in iris oscillation. The optimal value is lens dependent. Larger lenses typ-

ically require a larger drive voltage.

LensPIris

P-Iris lenses only. P-Iris allows discrete iris positions using an internal lens

stepping motor.

LensPIrisFrequency [Integer] R/W

Stepping motor drive rate. Lens dependent. Use value defined in GT camera user

manual, or contact lens manufacturer.

LensPIrisNumSteps [Integer] R/W

Maximum number of discrete iris/aperture positions. Use value defined in GT

camera user manual, or contact lens manufacturer.
