|Function:||Defines MAC-address of the DS|
|Set (S) command format:||SFExxx.xxx.xxx.xxx.xxx.xxx, where xxx.xxx.xxx.xxx.xxx.xxx is the MAC-address in the dot-decimal notation (i.e. 0.2.3.4.120.240)|
|Change takes effect:||After reboot|
|First introduced:||Earlier than "baseline" V3.14/V3.51|
Each DS is shipped from the factory with unique MAC-address already assigned to it. DO NOT change this address unless you have a good reason to do so. If you do change the address remember that the first digit of the address must be even!
Since the MAC-address of each DS is unique it may be used for device identification. It is returned by the Echo (X) command and also used to address a particular DS in the Assign IP-address (A) command and Select in Broadcast Mode (W) command .
This setting's mnemonic- "FE"- has to do with the previous name of the setting- "Factory Ethernet Address". Mnemonic was preserved to ensure compatibility with previous firmware versions.
