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, typical
voltages when the supply is 3.30 V. (If the sup-
ply voltage is e.g. 3.315 V, the table should
be corrected by multiplying these values by
3.315/3.3).
