Specifications of CV500-ZS3AT1-EV2

Lead Free Status / Rohs Status
Lead free / RoHS Compliant
Single Expansion I/O Rack
Racks
2-2-3 Expansion I/O Racks
Termination Resistance Unit
A Termination Resistance Unit
must be connected to the unused
I/O Connecting Cable Connector
when an Expansion I/O Rack is
not connected.
I/O Connector Connects Expan-
sion I/O Rack to preceding Expan-
sion I/O, Expansion CPU, or CPU
Rack.
I/O Connector Connects Expan-
sion I/O Rack to next Expansion
I/O Rack. When not used, connect
to a Termination Resistance Unit.
I/O Interface Unit (CV500-II201)
Connects the Expansion I/O Rack to
other Expansion Racks, the CPU Rack,
and/or an Expansion I/O Rack.
Expansion I/O Racks, shown in the following diagram, can be used to expand
the CV-series PCs. There are five models of Expansion I/O Backplane that can
be used, as shown in the following table. These vary in the number of slots that
they provide for Units (other than the Power Supply Unit and I/O Interface Unit)
and in expansion capabilities. CV500 Expansion I/O Backplanes offer complete
expansion capabilities, while CVM1 Expansion I/O Backplanes do not support
I/O Interface Units and thus must be connected directly to the CPU Backplane
(see Single Expansion I/O Rack in this subsection).
An Expansion I/O Rack can be connected either directly to the CPU Backplane
(see Single Expansion I/O Rack in this subsection) or to an I/O Control Unit.Up to
seven Expansion I/O Racks can be connected to the I/O Control Unit on the CPU
Rack in two series unless an Expansion CPU Rack is connected, in which case
only six Expansion I/O Racks may be connected. If an Expansion CPU Rack is
connected, one of the series of Expansion I/O Racks is connected to the I/O
Control Unit on the CPU Rack and the other one is connected to the I/O Interface
Unit on the Expansion CPU Rack.
Attach a Termination Resistance Unit to the unused terminal on the I/O Interface
Unit of the last Expansion I/O Rack in each series. If two series of Expansion I/O
Racks are used, connect a Termination Resistance Unit to the last Rack in each.
If only one Expansion I/O Rack is required and no Expansion CPU Rack is used,
a single Expansion I/O Rack can be connected directly to the CPU Rack without
an I/O Control Unit or I/O Interface Unit. The Racks are connected directly via the
connectors on the two Backplanes. Termination Resistance Units are also not
required. In every other respect, the Expansion I/O Rack is identical to Expan-
sion I/O Racks in connected via I/O Control and I/O Interface Units.
