At my company we have several USB barcode scanners. I'm not sure exactly what model they are, but I think they are the FG9800 from Farsun because that's what they look like on the exterior. They came with a programming manual that is very similar to this document from the Farsun website.

When I scan the "Output Firmware Version" barcode, my scanner types the following into the computer:

  Farsun    V2.00    2011-01-01    

Is it possible to configure these scanners so they only read barcodes in response to the trigger button being pressed? I don't want them to automatically read barcodes. Additionally, I want this setting to be remembered while the scanner is turned off.

Since this scanner only has a USB port, the only way to configure it that I know of is to scan bar codes from the manual (or make your own). I have tried scanning the configuration bar codes for Single Scan (013300), Single Scan No Trigger (013301), and Laser/CCD Timeout - 5 Seconds (0134005) from this document. Sometimes (but not often) this puts the scanner in to the right mode, where it only scans when the button is pressed. Unfortunately, the scanner seems to always leave this mode when it is power cycled.

I have also scanned the "Reset Configuration To Defaults" barcode (0B) many times.

We have three different scanners like this and I have not been able to successfully configure any of them.

If the things I want are not possible with these Farsun-based scanners, is there some other scanner we can use?
