RM-67X Series
32 Software Introduction & Installation
4.3.5 Shutter
Figure 27. Shutter Control Set
• Shutter Speed
The RM-67x can be set for a range of shutter speeds by selecting the desired speed from the drop down list box. The speed
is adjustable in increments of one horizontal line time (~64 us), from 1 to 312 lines.
4.3.6 Trigger Modes
−
Off: No triggering
−
Async Reset: A single pulse on the trigger input causes the video timing to reset to the start of a
video frame.
−
Edge Pre-select Mode
−
Pulse Width Mode
4.3.7 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.
4.3.8 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.
−
75 ohm terminates in 75 ohms.
