3.5.2
Initial setting of an A2CCPU
The A2CCPU allows connection
of up to
1 4
remote terminals (such as
A64RDC modules). In order to use those remote terminals, it is necessary to
set the remote terminal information in the A2CCPU in the initial setting.
The setting procedure varies with the system disk such as SW4GP-GPPAEE
and the previous type used for booting. Table
3.3
shows the setting proce-
dures including the setting descriptions and the differences between types
of
system disks.
