Execute Read when the input on
the Parallel TRIG Signal is ON.

Serial Data
Continuous Read
With no Parallel TRIG signal used,
the code reader executes Continu-
ous Read.

Continuous Read 1 Output

Continuous Read Auto
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)
Output Mode: Pulse
It turns ON when there is a Good Read or when it matches with the master symbol (if using the
Matchcode
function).
• Output 3: Mismatch (or on
No Read
)
Output Mode: Pulse
It turns ON when there is a
No Read
or when it does not match with the master symbol (if using
the
Matchcode
function).
