10.2 Radio
10.2.1 No Activity
If communication over the radio link has been lost and the unit at the other end of the link can
be managed on its local network, the following procedure should be adopted:
If there is no wireless activity then the configuration should be checked. It is essential that the
following items are correct:
•
Check for Alarm conditions on Home page
•
Check that the software at each end of the link is the same version
•
Check that the Target Mac address has not been mis-configured at each end of the link.
•
Check
Range
•
Check Tx Power
