Step1. Make sure the Barcode is detected in COM3. If it displays [COM3, 1 SICK]
as in the above figure, it is normal. If it does not display [COM3, 1 SICK],
you can click [Retry Com] to search it again. If you still can not find it, you
need to check the hardware and see if it is in good order (refer to the
hardware configurations at point 1)
Step2. If the “quiet zone” is too narrow (as shown in the following figure), it will
cause the barcode to be hard to be identified and you have to select [Narrow
Quiet Zone].

Step3. Press [Laser On] button to start the laser and adjust the scanner so that the
laser and the barcode to be scanned are at position as shown in the following
figure.
Step4. If the barcode space is too small, you can turn the scanner to an angle as
shown in the following figure to facilitate the reading.
Step5. When the barcode position is certain, click [S0 Focus] to maintain the
barcode at a fixed position and let the scanner read its focus and frequency.
When it is done, the barcode gives off a buzzing sound, the focus and the
frequency are also changed automatically.
Step6. If it is a dual barcode, you still have to adjust well the position of the scanner
and then click [S1 Focus] to set the focus and the frequency for Scanner 1.
Step7. After setting Scanner 1, click [Download to sick] button to save the setting in
the Scanner.
3.3.1.3 The detailed explanation of barcode setting
l Fill in the column of [Num.Of Barcodes] the total number of barcodes necessary
to be read. (For example, if each of two Scanners reads two barcodes, this
column is filled in 4)
l The default value for [Resolution] is 20. The smaller the number, the better the
resolution. Normally speaking, you do not have to change the value. If the
barcode material is so special that it is hard to read, you have to adjust this value
to make it easier for reading.
l You can fill in the bit number of the barcode in [Barcode Length]. After you set
the bit number, the scanner can only read the barcode with the number you have
set. If there are many kinds of barcode on a board, you can use this set number to
screen out the correct barcode to read. The default value at 0 means no limit for
bit number.
l [Trigger Mode.] – Selecting [Trigger Ext.] means that the laser turns on only
when there is an outer trigger occurred. Selecting [Trigger Free] means that the
laser of barcode scanner is always on. Selecting [Off-Line] means that the Sick
Scanner
