IntelliTouch controller power-on diagnostic codes are typically displayed when an

Elo driver is loaded, or through the Touchscreen Control Panel. The codes may be

a single byte or pair of bytes displayed in hex.

The following tables for each controller list the bit positions defined for each byte.

A 1 bit indicates a failure. Diagnostic codes are computed by summing the value

for each bit position using hexadecimal arithmetic.
