Gamma (Factory default setting = 1.0)
Gamma adjustment affects the linearity of the video signal with respect to the incoming light. The software offers to two
gamma options, 1.0 and 0.45. The 1.0 setting captures an image while maintaining a linear relationship between incoming
light and output video level. The 0.45 setting creates a nonlinear relationship that corrects for the nonlinear manner in
which most video monitors display an image. The 0.45 setting is typically used when an image will be viewed on a video
monitor. The 1.0 setting is typically used when the image will be captured by a frame grabber and undergo subsequent
image processing.

MFI Input (Multi-Function Input)
One of the inputs available on the rear panel, the DB15 connector, serves multiple functions. The MFI Input selection allows
the operator to choose the one that best serves the application.
VD Input is used for genlocking to a vertical drive input
CSYNC is used for genlocking to a composite sync input
Trigger Input is used for one of several trigger modes

MFI Termination
This option allows the option of terminating the MFI in either 75 ohms, or a high impedance.
−
HiZ setting terminates in a high impedance.
