I/O FUNCTION
This chapter describes the I/O function re-
lated to data input and output.
7.1 Overview of the I/O function
According to the I/O-type selection parameter, the I/O connector will
perform tolerance judgment output, BCD output, and segment output.
Each output can be performed in the NORMAL mode, calculation
mode, or high-speed mode as set by the I/O function selection param-
eter. (Refer to chapter 3 SETTING PARAMETERS.)
NOTE
The user must separately purchase the connection cable.
