The common driver software must be obtained directly from LK. It must be installed and configured prior to attempting to install/use the PC-DMIS interface that utilizes it. LK provides instructions for installation/setup. This document assumes the common driver is installed and configured and focuses on the setup issues specific to the PC-DMIS interface.
The common driver DLL itself is named something similar to LKCMMDRV53.DLL, depending on the version number of the driver. There are also various other DLLs that LK provides the driver that must be present for the driver to work properly. The earliest version that can be used with the PC-DMIS interface is LKCMM21.DLL. Earlier versions are not compatible.
If you are running the 5.3 version of the common driver, then a program from LK needs to be run in order to "link" PC-DMIS to the driver. The program is called SetCmmPath.exe and is located on the FTP site under 3rdParty/LK.
