With the C200H Host Interface Units, the interface is set up simply by con-
necting with cable to the C200H CPU Rack or Expansion I/O Rack. It is also
possible to connect to C20H, C28H, C40H, and C60H CPU Units or I/O
Units. Be sure to use a noise filter when connecting CjjH. Refer to the
Host Interface Units Operation Manual for details.
In a C200H PC System, you can ordinarily connect two Expansion I/O Racks to
the CPU Rack. The C200H Host Interface Unit itself, however, functions as an
Expansion I/O Rack, and therefore when using a C200H Host Interface Unit, you
can only connect one other Expansion I/O Rack.
