AVT GigE Camera and Driver Attributes V1.3.1

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

IrisVideoLevelMax – Uint32 – R/W

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

iris.

IrisVideoLevelMin – Uint32 – R/W

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

lens iris.

LensDCIris

DC Iris lenses only.

LensDCDriveStrength – Uint32 – 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 optimum value is lens dependent. Larger lenses

typically require a larger drive voltage.

LensPIris

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

stepping motor.

LensPIrisFrequency – Uint32 – R/W

Stepping motor drive rate. Lens dependent. Use value defined in application

note on supported P-iris lenses or contact lens manufacturer.

LensPIrisNumSteps – Uint32 – R/W

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

application note on supported P-iris lenses, or contact lens manufacturer.

LensPIrisPosition – Uint32 – R/W

Iris/aperture position. Manually control iris in PIrisManual mode, or read iris

position in PIrisAuto mode. 0 = fully open, LensPIrisNumSteps = fully closed.

Values greater than LensPIrisNumSteps are ignored/not written.

Range: [0 – 150] Default: Camera dependent Units: 10 mV [Manta: 13.2 mV]

Range: [0 – 50] Default: 10
