Troubleshooting
3. Check the port status LED.
A status LED should be illuminated amber
if you expect a TekLink connection to exist.
There are periods of time when TekLink
will not function:
When an instrument is fi rst powering on;
the operating system drives the TekLink
hardware and it is necessary for the
operating system to be running to establish
a TekLink connection.
When a hub is fi rst powering on: the
hub will perform initialization tasks before
establishing a TekLink connection.
Failure implies the cable may be bad, the
TekLink Ethernet device in the instrument
has failed, or the Ethernet system in the
hub has failed.
