Problem:
Unit does not collect bus traffic in Trace Mode.
Solution:
1. Check cable connections at the unit and bus. When using the Test Cable,
confirm SCL, SDA, and GND clip leads are connected to appropriate bus
lines.
2. Check Selected Address. If a single bus address is specified, only messages
directed to that address will be collected. Confirm presence of bus traffic by
monitoring all bus addresses.
3. When using the External Trigger Port, the unit will wait for a trigger event.
Check the TRIG input using Line Status Mode. A High-to Low transition,
with minimum 2usec Low duration, is required to generate a trigger
condition.
