Wang 200 Series - Remote Initial Program Load (RIPL) Board

1. 2 Settings
UPCC
1.2.2 Remote Initial Program Load (RIPL) Board
The 1 0-position dual in-line package
(DIP) switch bank on the RIPL PCB is
used to select a unique 1/0 address
for the board. 1/0 address conflicts
will result if two active 1/0 devices
within the system try to access the
same 1/0 address. To minimize this
possibility, primary or "default" 1/0
address switch and jumper settings
have been established for boards
in computers containing the UPCC.
Defaults represent standard
settings that should always be used
unless a combination of boards
results in a conflict. If such a
problem occurs, the 1/0 address of
one of the conflicting devices must
be reconfigured to an alternate or
secondary setting.
