LED Indicators Continued…
Important: The BA-220 DualBeam will not read the exact same
barcode number until at least 1 second has passed since the first time
it was read. Remember to wait 1 second between reads before trying
to scan the same barcode. If you try to read it again sooner, the
BA-220 DualBeam will ignore it. If a different barcode number is read,
you will see the green indicator light. The only time you need to wait 1
second between reads is if you have only 1 barcode number to test
with.
As you pass the barcode through the laser line watch the two red
LED’s (Data0 Act and Data1 Act) that show the status of the Wiegand
data lines. When the barcode is read, both should “flash” or “flicker”
red very quickly. These “flashes” indicate that the BA-220 DualBeam
has sent out the Wiegand communication pulses for the barcode.
Note: These “flashes” are very fast - to be certain to see them look
directly at the indicators and shade them from the Sun if necessary.
At this point the BA-220 DualBeam is ready for operation.
