Does the NL100 have a MAC address? If so, how do I go about determining the address? Thank you!
The MAC address is also known as the device's physical address. Why we don't use "MAC" in our manual? That's a great question, and something we should probably change.
You can use Device Configuration utility (ftp://ftp.campbellsci.com/pub/outgoing/files/devconfig_1.17.exe) to query the MAC/physical address.
You can also use a terminal program like HyperTrm to connect to the device and query the MAC address. The menu option or command is "Ver". See section 2.4.1 of the NL100 manual.
I'm not positive, but I think you could also get this info remotely using Telnet.
