Select “Ethernet Status” from the “Maintenance Data” menu.  
 
This screen only appears in instruments that have the Ethernet Communications option. 
Essentially, this screen shows the same Ethernet diagnostic messages as available on the 
controller via the lower display window. See Section 7.5 for details. 
The Ethernet Status screen shows the network status of the Ethernet Link. This m
ay be 
accessed either via Ethernet or via Infrared communications. Not all diagnostic messages 
are available via Ethernet Communications. For example, if the Ethernet cable is 
unplugged, then the instrument cannot send up the “EUNPLGED” diagnostic message 
via Ethernet.
