MDot EUI

[Tom Hill]

We’re wondering how the MDot EUI is formatted. We see that it’s an 8 byte value but are wondering if we can truncate it by 4 bytes for purposes of minimizing it’s size.

Stated a little differently, is the entire 8 bytes used to provide a ‘globally unique’ number but a smaller portion of the EUI (say 4 bytes for example) can be relied on to be ‘locally’ unique.

We ask because we’d like to store a 4 byte value in our server. When the server sends a request to the Multitech Conduit, it would only transmit those 4 bytes. The Conduit would then add the other 4 bytes (we’d hard code those into it if we can safely assume they’d never change) when it needed to transmit data to a specific MDot node.

Please advise as to whether this can safely be done.

Thanks, Tom
