1. Overview 2. Installation & wiring
Maximum flshing time of emitter LED is affected by frame arte and Flashing mode.
Each light's maximum lighting time is as follows.

If read time out elapses, all processes will cease
z
Make sure you choose a decode timeout value that is less than the Reading timeout value
z
Filter time can be set at any value between 1 to 100ms
z

External Output Timing Chart

z OK/NG Output
OK Output turns ON when Reading Success or Verification Success occurs
NG Output turns ON when Read Failure or Verification Failure occurs
Operating logic of output can be chosen from "positive logic" and "negative logic".
The timing chart when set to [positive logic] is as follows:
Reading Request
Image + Decode
ON
External Output
(OK/NG)
OFF
Output enable time can be set as infinite, or any value between 10 to 2,550 ms.
z
While OK Output or NG Output was on, when a reading request became on the outside output is turned off
z
compulsorily.
