I have a Newland NLS-BS80 Bluetooth Barcode Scanner and it has a "Restore Factory Defaults" Barcode in its manual printed in paper.

This barcode instantly reset the device to its factory defaults, so I want to create a web link based image of it for use of my co-workers.

So I scanned this Barcode with a Barcode Scanner app in Android to find out what is behind it and I found that its actual value is $$%^1207 but I don't know why when I make a Code-128 barcode in a online tool that contains same $$%^1207 value it can't reset my device?

The device just treats it as an normal barcode not a special reset one.

So where I'm doing wrong? Thanks.

Original factory reset barcode

  • Why not use an actual hi-res picture scan of the barcode? – Señor CMasMas Aug 23 '22 at 15:36
  • I know that I can do that but I'm just curious that what's difference between this two identical barcodes and how the device detect it that its not the original one? – AntiDictator Aug 23 '22 at 15:37
  • Both not the same barcode type? (aka not both code-128). Not being rendered with the correct font? There are so many reasons they might be different. – Señor CMasMas Aug 23 '22 at 15:50
  • No both are Code-128 and I don't think font is important because I tried many different barcode generators with different fonts. – AntiDictator Aug 23 '22 at 17:06

Your barcodes are not the same.

Yours is simply $$%^1207 while the original one is <FNC3>$$%^1207.

Encoding FNC3 is dependent on your encoding program. Try perhaps to add ^3 to the beginning of the barcode data.

  • So how can I make a FCN3 barcode? I'm using https://lindell.me/JsBarcode/ library for javascript but it can't create a FCN3 code-128 barcode. What is a FCN3 barcode and if there's any chance that I can create this barcode at all? – AntiDictator Aug 23 '22 at 17:01
  • Many thanks, I found it with your guide, the solution is here: https://github.com/lindell/JsBarcode/issues/162 – AntiDictator Aug 23 '22 at 17:10
  • I just needed to add \xC9 to the beginning of barcode data – AntiDictator Aug 23 '22 at 17:14
