Dear BWR ??
The LED parts that you have from CPS are for the FDS Panels.
The Display PCB Board from FSBUS are to big and alone for bigger LED Parts...not for the small Window at FDS/AGT Panel.
CPS has built a lot of special PCB Display Boards for the FDS Panels and AGT Panels.
Ask Mathias please, for the right one of LED Display PCB Boards.
Regards
