when the connection is made to an active network and it blinks when any message
packets are detected.

of the RJ-45 connector. They show:

Normal Operation: Steady green LED. The power supply has an active LAN
connection.

Device Identify: Blinking green or red. The identify function is turned on from a
remote computer using the web page or a SCPI command. The front panel blinks

instruments. The blinking is turned off by the web page, by sending the 'blink off'
SCPI command, or by changing any front panel control.
