Characteristic Performance requirement Reference information
Ground Closure Input
signaling TTL thresholds, 5 V max
input, –0.5 V min input. Pull
low to assert. Has internal 10 k Ω pull-up to 5 V on each input. Direct or
encoded inputs must be asserted and stable for at least 150 ms
to be recognized reliably. Inputs that are stable for 75 ms or less
will never be recognized.
