OMI 2.3.1 Release Notes

OMI 2.3.1 Release Notes 43

OMI Now Uses DMA at All Times

OMI 2.3 automatically uses direct memory addressing (DMA) whenever possible to

speed up transfers of live video from the frame grabber to the PC’s video card for

display. The Use Video DMA setting of the Object Manager (available in the Object

Manager’s Properties dialog and with the SetUseVideoDma function) no longer has any

effect.

Form Containing Display OCX Must Use Correct

Palette

If your Windows desktop is set to 256 colors, you must use the correct palette for each

Visual Basic form in which you have inserted the OMI display OCX. You must set the

PaletteMode to Custom and set the Palette to the standard OMI palette (supplied in

sample/vb/omipal.bmp).

Object Manager Notes

Global Objects Referenced by Other Objects

Cannot be Reloaded

Global objects referenced by other objects cannot be individually reloaded into a

project in which they already exist. You must perform a NewProject() call or delete the

current instances of the global objects before attempting to reload them.

Image Acquisition Notes

Genlock Supported for One Camera Port on

MVS-8110

You can only configure one camera at a time for genlock acquisition using the

MVS-8110. Configuring multiple cameras to use genlock causes image corruption.

Using Two Digital Cameras with CVM6

If you are using two digital cameras with a Cognex MVS-8120/CVM6 or an

MVS-8110/CVM6, you must use the following procedure, or you may encounter

difficulties.
