Setting the Device Instance (Coupled MAC and DI)

Device Instance:
A Device Instance number identifies a device within an entire building, therefore giving it a unique number or Address,
much like a telephone ext. number. A building can have one telephone number, but all the extensions have a unique
number to identify them. A Device Instance number would work the same way and must be unique throughout the building.
Below is a table defining how a Device Instance number is obtained.
Note: Each device on a network segment must be set to run at the same speed or baud rate.
