Has anyone run across a light stack (like something that would be on top of a piece of heavy equipment on a factory floor to tell the operator that there's a problem that needs addressing) that - has multiple lights of relatively standard colors (e.g., read, yellow, green, blue) - allows each light to be independently controlled (on/off/ flashing) - allows control via RS-232 or USB (with the latter either emulating an RS-232 connection via an internal converter or having Linux 2.6.23+ support) - has audio output (audio alarm) - has software volume control for the audio - (bonus) allows programmable audio files for driving the audio output
I know Patlight makes some stuff that comes close, but they don't seem to have software volume control or RS-232/USB support.
Anyone seen anything that would fit the bill?
Thanks Jeff
