Aux In
In this section you can enable the Aux In port to control the output
pattern. Aux In can receive signals that control alternate patterns or
blank the output.
The signals received at this port must be TTL-compatible. The
granularity for signals at this port is 512 bits.
The following options are available for
Aux In
:
•
Disable
With this option selected, the signal at the Aux In port will be
ignored.
•
Level Sensitive
– If
Aux In
is logic high, pattern B is sent.
– If
Aux In
is logic low, pattern A is sent.

Edge Sensitive
Pattern A is sent out until a rising edge at Aux In is detected. Then,
at the next complete repetition of pattern A, a single occurrence of
pattern B is inserted into the output.
