Diagnostic LED's

Depending on where the controller is installed, the LED's may or may not be 
visible.

IntelliTouch Serial Controllers

The IntelliTouch serial controllers have one green diagnostic LED. Following 
power on, the controller performs a short self-test, where the LED stays lit. 
After the self-test, the LED flashes once per second, indicating normal 
operation. The self-test results are displayed by most Elo driver software.

During normal operation, the LED also indicates controller/host communication 
is in progress. When the touchscreen is touched, the LED should light 
continuously, then return to the normal flash rate. If the host does not remove 
the packet from the controller, the LED will stay lit.

The LED will also stay lit without a touch if the touchscreen or cabling is 
disconnected or not functioning.

If the LED flashes about two times per second, a warning error condition is 
indicated, such as improper communication from the host. Suspect an invalid 
command sequence from the host.
