The interface DLL for the Zeiss GPIB/RS-232 Direct interface is named zssgpib.dll.
The PC-DMIS Settings Editor section for this interface is named "Zeiss".
This interface supports the GPIB Zeiss controller. This controller is a gray, 2-foot-square box.
The PH9 is controlled through an RS-232 port.
PC-DMIS supports a native RS-232 connection (Zeiss C99 controller) with this interface. For this connection, the ZSSRS232.DLL file drives the Zeiss CMM through the Zeiss UMESS/COMET software package.
The RS232CMM entry in the Zeiss section of the PC-DMIS Settings Editor specifies whether PC-DMIS communicates with GPIB or RS-232. For a native RS-232 connection, this entry should be set to 1.
