I have a system with two HRP5-120 processors running Illumination 1.65 software. I have 13 various STRD keypads (STRD-6BRL, STRD-7B, etc.). When the system was first set up (8 years ago) all of the backlights on the STRD keypads worked as expected. Somewhere through various Illumination software upgrades and programming changes the STRD keypad backlights stopped working.
I have checked each STRD keypad's properities in the Programming tab and the Backlight Brightness is set to "High". I checked in the User Preferences under Current Project Defaults and the Backlight Brightness is set to "High". I have tried setting an individual STRD keypads Backlight Brightness to "Off", uploading the project, and then setting that keypads Backlight Brightness to "High" and uploading the project. The backlight on that STRD keypad still does not turn on. I have tried un-assigning the address from an STRD keypad and then re-assigning the address to that keypad but the backlight still does not work. A few months ago I added two additional STRD-6BRL keypads to the system. The backlights work properly on the newly added keypads.
I'm at a loss as to what to do next. I read online that I should re-create the project from scratch but that would be a huge job that I would prefer to avoid if I can since beyond the 13 STRD keypads the project also has 16 other keypads (HRD and HRT) and 65 dimmers with a lot of programming.
Any help would be greatly appreciated.
