If you are unable to find your clock on the network, there are multiple possible causes. To distinguish what the causes are, consider whether the unit was brand new out of the box, or whether it was not discoverable after a firmware upgrade.
Brand New Clock
If the clock is a brand new clock it is possible it has automatically reverted back to a link-local address. To fix this plug the clock and a computer into a DHCP server and automatically allocate an IP address. Alternatively, press the button on the front panel to rotate the display to show the IP address of the clock, and set your PC IP address to be on the same subnet as your clock.
After Firmware Upgrade
If the clock has disappeared after a firmware upgrade there could be multiple different causes. To fix this a user should try reverting back their IP address back to their original one. If a light is flashing rapidly, try the firmware upgrade again, connect to the clock directly, change the firewall settings to allow packets through and if there is still no luck discovering the clock on the network try connecting to it via a switch.
Some other solutions we can suggest to try and troubleshoot this issue include:
- Retrying the upgrade through a power cycle and then try discover the clock using the Tekron Config Tool
- Run a Wireshark capture and see if there is any response from the clock.
If none of these troubleshooting methods work, please contact firstname.lastname@example.org and they will arrange for the unit to be returned so the unit can be investigated.
