### Step 2: Installing the Pcdmis.dat File on the CATIA system

Pcdmis.dat is a simple data text file containing network information that allows CATIA to communicate with the Windows 95, Windows 98, Windows NT, Windows 2000, or Windows XP operating systems.

1. Place Pcdmis.dat into the Pcdmis directory on your UNIX workstation. You can also download this file from ftp://wilcoxassoc.com/dci/catia/

2. Edit Pcdmis.dat so that it contains the necessary port and IP address information of your UNIX workstation as shown in "Example of the Pcdmis.dat File on a UNIX Workstation" on page 27. If desired, you can also edit this file with these two additional options:

Option | Description
DEBUG | Turns on the generation of a debug file. This file is a communications log of the Windows system with the UNIX system. It also contains the processing occurring on the UNIX system. Note: Use care with this option as it can generate a very large file that could tax your system's resources.
EXIT | Exits PCDCAT (interface file) each time you exit PC-DMIS. If this isn't used, PCDCAT never exits but continues to run, waiting for PC-DMIS to communicate with it.
PORT2 | If EXIT is not set, then PORT2 should be set to an open TCP/IP port. PCDCAT will then spawn off a separate process whenever PC-DMIS connects to it. This allows PC-DMIS to be always on, waiting for a connection from PC-DMIS, but only using CATIA licenses when PC-DMIS is connected to it.
