Expansion connector
A PC with 128 I/O points (the maximum) can be assembled by connecting three
Expansion I/O Boards. The following configuration provides 64 inputs and 64
sinking transistor outputs:
CPM2B-32C1DT-D
(16 inputs, 16 outputs)
CPM2B-32EDT
(16 inputs, 16 outputs)
× 1 Board+ × 3 Boards = 64 inputs, 64 outputs

Note When an NT-AL001-E Adapter is connected to the RS-232C port, only one Ex-
pansion I/O Board can be connected because of power supply limitations.
