Control system alternative interface
This is kind of go back to old days. Low end customers need some low cost simple interface to show them important messages, such as critical alarms.
Solustion 1 - Buzzer
More and more controller support UO, which, in binary mode, provides 12Vdc output when it's activated. Mini 12VDC Electric Buzzer from Radioshack has been successfully used in a project.

Solution 2 - big LED display system
My current selection is www.adaptivedisplays.com, simply because it provides the protocol details. I need to spend some time on the drive development and test.
Solution 3 - small Serial LCD
My current selection is melabs Serial LCD (SLCD). Yeah, it provides protocol too.
