Remarks
When MEDiasense is enabled, this feature detects a loss of LAN
connectivity of greater than 20 seconds, and then, on sensing a
reconnection, re-starts the LAN.
When MEDiasense is disabled, there is no detection of loss of LAN
connectivity.
From the factory, the MEDiasense setting is enabled (ON).
The MEDiasense setting is stored in non-volatile memory, and does not
change when power has been off, after a Factory Reset (*RST command),
or after an Instrument Preset (SYSTem:PRESet command).
