DC Media's default screen control extension (aelcdmonitor) handles some NEC displays, however due to the way in which NEC codes are structured it is not possible to have it cover every possible combination of the NEC codes.
To maximize the number of NEC 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 NEC in the configuration dialogue
3. Include the attached customrs232.ini file in the dcmedia folder at (c:\Users\Public\documents\dcmedia\)
