3. Set the destination network address to 00 to transmit within the local net-
work. When two or more CPU Bus Units are mounted, the network address
will be the unit number of the Unit with the lowest unit number.
4. Port numbers 1 and 2 indicate serial ports 1 and 2 (physical ports) of the
destination device when sending a FINS command to a host computer via
a Host Link Network.

6. The maximum node number depends on the network being used. For a
Controller Link, the allowed range is 00 to 20 hexadecimal (0 to 32). Set
the destination node number to FF to broadcast to all nodes; set it to 00 to
transmit within the local node.
7. Refer to Automatic Allocation of Communications Ports on page 872 for
details on using automatic allocation of the communications port number
(logical port).
8. When the destination node number is set to FF (broadcast transmission),
there will be no response even if bits 12 to 15 are set to 0.
