Controlling Operation and Data Output
with Parallel I/O
This section explains how to directly connect the code reader to an external device by the I/O cable
and the methods that you can use to control the code reader from the external device.

Basic Operation with a Parallel I/O Connection

2-1-1
This section describes the basic connections and signal flow with external devices.
Operation for one of the primary uses is described in the example below.
Trigger sensor
Example of Trigger Input and OUTPUT signal
Below is an Output assignment example and Timing chart.
[Example assignment of OUTPUT signals]
• Output 1: In Read Cycle
It turns ON while the code reader is in its Read cycle.
• Output 2: On Match (or Good Read)
It turns ON when there is a Good Read or when it matches with the Master Symbol (if using the
Matchcode function).
• Output 3 : On Mismatch (or No Read)
It turns ON when there is a No Read or when it does not match with the Master Symbol (if using
the Matchcode function).
For how to set up the Output signal assignments, please refer to How to Assign the Output Signals on
page 2 - 10
