Troubleshooting
The time is incorrect.
Red status LED is always on.
Possible reasons/solutions:
1.
The ADC-A12C31 is not currently connected to a valid time code reference.
2.
There is a problem with the cabling between the ADC-A12C31 and the time code reference. Verify
that all cables and connectors are in good condition.
3.
There is a ground loop or other type of interference between the ADC-A12C31 and the time code
reference. Verify that a common ground exists between the ADC-A12C31 and the time code
reference. If the cabling distance between the time code reference and the ADC-A12C31 is large
you might consider inserting an audio distribution amplifier or an Imagine Communications
Corporation TCA100 time code amplifier in-line.
4.
The signal level of the incoming time code is out of the range of the ADC-A12C31’s time code
decoder’s circuitry. See the ADC-A12C31 specification section for acceptable signal level ranges.
5.
The time code reference, to the ADC-A12C31 is not a recognized format. Verify that your time
code reference is providing one of the time code formats that the ADC-A12C31 can decode.
Not displaying the correct [local] time.
Possible reasons/solutions:
1.
The unit is not receiving time code. Verify that the front LED status indicator is off.
2.
The time code reference is referenced to UTC but your local time zone has not been configured.
3.
Your DIP switch settings for DST may have been overridden by ADC-Set configuration utility.
4.
You may be seeing the result of a double offset. Determine the time zone reference of your time
code reference and then set the ADC-A12C31’s time zone offset to arrive at a correct local time.
If the time code reference is already providing time code with local time zone and/or DST
offsets, then set the time zone and/or DST offset of the clock to UTC.
If the time code reference is providing UTC time code, then configure your clock to have a
local time zone and/or DST offset.
5.
Your time code reference is not providing the time/date that you expect. Contact the individual
responsible for the time code reference for more information.
