Node Number
30
If more than one Controller is connected to a single host through Link Adapters,
each Controller needs an ID number so that the host can discriminate each of
them. Such an ID number is called node number. Each Controller must have a
unique node number.
Each command or response of the Controller includes the node number of the
Controller. Communications will not be possible if the node number is wrong.
The node number must be correctly set regardless of whether the host is con-
nected to a single or multiple Controllers.
As shown below, SW1 on the left is for 10's digit and SW2 on the right is for 1's
digit, which can set numbers within a range between 00 and 31.

The node number switches are factory-set to 00.
Note Do not set the node number within a range between 32 and 99, in which case the
node number will automatically be set to 31.
