1-2-2 CPU Unit and Expansion I/O Unit
Up to 5 Expansion I/O Units can be connected to the Expansion Connector.
There are three models of Expansion Units available: the Expansion I/O Unit,
Analog I/O Unit, and CompoBus/S I/O Link Unit.

A PC with 140 I/O points (the maximum) can be assembled by connecting five
Expansion I/O Units to a CPU Unit with 20 I/O points.

Note Be sure that the power supply requirements of the CPU Unit and Expansion I/O
Units do not exceed the available capacity. Only three Expansion I/O Units can
be connected when the NT-AL001 Adapter connected to the RS-232C port.
