In Table 2, voltages outside the limits mentioned
are to be considered invalid. No action is taken
if invalid measurements are made. GPI recall ac-
tion resumes when a stable, valid measurement
is detected again.

Table 2: GPI voltage windows
Notes:
►
"Idle" refers to the state when no input is con-
nected, or when the input is left floating.
►
Rather than absolute voltage measurements,
the windows are defined as a fraction of the
supply voltage. This voltage can be measured
with a high impedance DMM on the D-SUB
pin 5 or 10.
►
The table shows values as a fraction of the
supply voltage, and, as a guideline, typi-
cal voltages when the supply is 3.30 V. (If
the supply voltage is e.g. 3.315 V, the table
should be corrected by multiplying these val-
ues by 3.315/3.3).
