RE: [ECOS] Question about MBX860 Redboot Ethernet connection

You can also set the 'locally administered address'
bit and then assign your own addresses inside your
network. Setting that bit really frees you from
worry about accidental duplication of addresses.
That is the second bit transmitted in the MAC address,
or for most devices (in hex form) 02 00 00 00 00 00
So you just pick a rational sequence for the rest.

All ethernet devices in the world need a unique address, at least
within the local network.

If you have Flash memory in your system, you can use RedBoot to
maintain this value.

Note: where the value comes from is another matter.  Technically, these
values are to be assigned by a global governance (i.e. purchased).  In
practical terms though, most any value can work as long as it is unique
within the local domain.

[ECOS] Question about MBX860 Redboot Ethernet connection

hi.
I got a simple question.
I wonder if MBX860 Module needs its own unique MAC Address or not?
( when MBX860 uses ethernet)
If needed, tell me how to set MAC address.

thanks.
