The device address set on the ADDRESS DIP switch block applies to the device connection on the bus where the

device is not the bus supervisor. For example, the DIP switches on FACs, FECs, or VMA16s (master devices) set

the device address for the device connection to the FC bus (or Remote Field Bus). If the FAC, FEC, or VMA16 also

supervise an SA bus, the FAC's, FEC's, or VMA16's address on an SA bus is 0 by default (Figure 7).

An IOM has only one device connection, which can connect to either an FC bus or an SA bus (but not both); therefore,

the device address set on an IOM applies to the bus to which the IOM is connected. (An IOM is never a bus

supervisor.)
