5.6. Diagnostic Tools
5.6.1. Cable Diagnostics
The cable diagnostics is a useful tool to determine any cable related
issues in case of TPS connection. The estimated cable length and
the quality of the link are measured periodically and the diagnostic
window shows the values in real-time. If the green bars hit the first line
in the middle they turn into red. It means the number of the errors –
during the extension – is higher than recommended. The link might be
alive but recovering of the received data is not guaranteed.
INFO: Each bar represents a differential line in the CATx cable. The
inappropriate termination of the cable usually causes high error
rates. Check the cable terminations or change the cable.
