The SPB demo application provided on the MK4000 should work with both the imager and laser versions. Please send me the SPB21.html from the \Application\SymbolPB folder. Tom Conticello

Tom, I'm speaking of the price-checker demo that also comes with MK4000 and in written for SPB (https://devcentral.symbol.com/shwmessage.aspx?ForumID=256&MessageID…) - not the SPB demo itself.

I found out that either when using Demo (https://devcentral.symbol.com/shwmessage.aspx?ForumID=256&MessageID…) or plain tutorial script from PB help file (see below) - scanner isn't working. The mirror _starts_ moving, but there's no laser beam. I also found out, that this does not depend on Rastering mode (I tried all of RASTER_ options) and that this happens only when Aiming mode is set to AIM_TYPE_PRESENTATION - as soon as I remove this tag or change it to AIM_TYPE_anything else - laser starts working. Is it a bug or one should use another way to enable presentation mode on MK4000 with SE950-based laser scanner? I think, if mirror is moving and no error is displayed - it's a bug. Unfortunately, I have no MK500 laser to test it also. Could someone do this? The example code I used:

var Generic = new ActiveXObject("SymbolBrowser.Generic"); function doSoftScan() { Generic.InvokeMetaFunction('scanner', 'start'); } function doScan(data) { bcode.innerHTML = data; doSoftScan(); }

Hi Arsen, This is the feedback from engineering: AIM_TYPE_PRESENTATION is only applicable to the imager versions of the MKs, for a laser device the application has to issue a soft trigger after a timeout or successful decode. Working on getting the demo to work with laser scanner. Andy
