Problems - Troubleshooting

Unable to communicate to slave display / clock

Possible reasons/solutions:

1. Verify the correct RJ12 (6P6C) modular cable is being used (i.e. 6 conductor).

2. Verify all connections are secure between the RC500 and slave display/clock.

3. Check to make sure power is applied to all devices.

4. Check the cables for hard bends, kinks, or cuts.

5. Verify that the correct adapters and splitters are being used (i.e. 6P6C).

Colons are flashing / Time is incorrect

Possible reasons/solutions:

1. The RC500 is not currently connected to a valid time reference.

2. There is a problem with the cabling between the RC500 and the time reference. Verify that all

cables and connectors are in good condition.

Unable to lock to time code

Possible reasons/solutions:

1. RC500 is not currently connected to a valid time code source.

2. Verify that all cables are properly connected.

3. Verify that all cables and connectors are in working condition.

4. The time code format being fed to RC500 is not recognized format.

5. Verify the time code reference is a format supported by the RC500.

6. Signal level of time code is not at acceptable levels.

Not displaying the correct local time.

Possible reasons/solutions:

1. The unit is not receiving time code. Verify that the colons on the LED display are on solid.

2. The time reference is referenced to UTC but your local time zone reference of your time

reference and then set the time zone offset to arrive at a correct local time.

3. If the time reference is already providing time with local time zone and/or DST offsets, then set

the time zone and/or DST offset of the RC500 to UTC. If the time reference is providing UTC

time, then configure your RC500 to have a local time zone and/or DST offset.

4. Your time reference is not providing the time/date that you expect. Contact the individual

responsible for the time reference for more information.

DST is not properly negotiated

Possible reasons/solutions:

1. Verify the DST is enabled on RC500

2. Verify that the correct format of DST is enabled (US/EU).

3. Check to make sure that you do not have DST enabled on both clocks and RC500.

Unable to discover the RC500 using WinDiscovery.

Possible reasons/solutions:

1. Verify that you have supplied power to the network device.

2. The discovery process was not complete. “After selecting the Discover” button, wait until the

discovery status indicates 100% completion.

3. Verify that the RC500 is on the same physical network as the computer from which you are

running WinDiscovery.
