6.0 Switch Settings
Set the address switch settings before connecting the DS7461i to the multiplex bus.
No two DS7461i Single Zone modules may be set to the same address. Having
two or more units set to the same address may prevent fault detection or cause
multiplex bus failure.
You can find the Address Switch Settings using the chart on the last page,
or by calculating the decimal number of the address.
