DC Media's default screen control extension (aelcdmonitor) handles some Christie displays, however due to the way in which Christie codes are structured it is not possible to have it cover every possible combination of the Christie codes.
To maximize the number of Christie models supported we have used dcmedia's ability to create custom codes and have published these publicly.
The steps to use the custom controls are below
1. Firstly ensure you are using aelcdmonitor.dll version 75 or greater
2. Select 'custom' instead of Christie in the configuration dialogue
3. Include the attached customrs232.ini file in the dcmedia folder at (c:\Users\Public\documents\dcmedia\)
