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. (If the CPU Rack is either
C200H-CPU02 or C200H-CPU22, it is not possible to connect both an Expan-
sion Rack and a PT.)

NT600M PT + NT600M-LB122-V1
The illustrations below show the front panels of PTs with and without touch
panels (i.e., DT-type and DN-type PTs) and PTs with function keys (i.e., DF-
type PTs). A 12-key Function Key Unit can be attached to a DN-type PT to
give it the same outer appearance and functions of a DF-type PT.
System Keys
Used for maintenance of the N600M,
selecting the System Menu, etc. Used
during operation for scrolling the
screen and inputting numeric values.
Dust-proof Cover (liquid crystal type only)
Covers the contrast control. Turning the
contrast control clockwise increases the
contrast.
Display
Touch Switches (touch panel type only)
Used as an input device corresponding to
the display screen.
