6-10 Setting the Bar Code Reader Input Function

The NT631/NT631C has a bar code reader input function which allows a bar code reader to be connected and bar code data to read as character strings into character string input fields.

This section describes the communications conditions for the bar code reader and the setting method for confirming the input data.

Reference: • For details on bar code reader types and connection methods, refer to 3-4 Connecting a Bar Code Reader in this manual and for details on how to use a bar code reader refer to 3-7 Input of Numeric Values and Character Strings in the Reference Manual.

The bar code reader is connected to serial port A. This means that serial port B must be used for communications with the host.
