CPU Bus Connector For connect-
ing an Expansion CPU Rack
I/O Connector Two series of Expan-
sion I/O Racks can be connected.
Both connectors have identical func-
tions.
To connect an Expansion CPU Rack,
connect one I/O connecter and the
CPU bus connector to the corre-
sponding connectors on the I/O Inter-
face Unit on the Expansion CPU
Rack.
An I/O Control Unit must be mounted to the CPU Rack in order to connect the
CPU Rack to an Expansion CPU Rack or to more than one Expansion I/O Rack.
Three I/O Control Unit models are available, the CV500-IC101 for connecting an
Expansion CPU Rack and/or CV-series Expansion I/O Racks, the CV500-IC201
for connecting just CV-series Expansion I/O Racks, and the CV500-IC301 for
connecting C500 Expansion I/O Racks. An I/O Control Unit can be mounted
even if no Expansion I/O or Expansion CPU Rack is used. The I/O Control Unit
must be mounted to the leftmost slot on the CPU Backplane.
