MULTIBUS CHASSIS HARDWARE
The multibus hardware consists of the multibus chassis and
the Network Interface Unit (NIU) modules. The modules are
discussed in this section.
Multibus Chassis
•
Elsag Bailey Part Number - L700806_1.
The multibus chassis provides the power and communica-
tion paths for the multibus NIU and keyboard modules listed
in Table
. Connect the modules into the slots as shown in
Figure
.
The OIS communicates with the INFI 90 OPEN system through
the Network Interface Unit (NIU), and is connected to the NIU.
The NIU hardware dipswitch settings are factory set and
should not require further configuration. Table
lists the
multibus modules in the IIOIS12 multibus chassis. The wiring
for the multibus chassis is shown in Figures
. and
CAUTION
Do not operate the OIS with doors or covers opened or
removed. Figure
