Chrome will not show PDF in MC40

Research member managed to setup P/N MC40N0-SCG3R01  MFD: 21MAY13 A KS

to scan bar code and get a PDF to display in Chrome browser.

 

We got several P/N MC40N0-HCJ3R01F  MFD: 24MAY15 A KS

And I matched to the mc40 the research person setup originally

 

Issue :

1st MC40 when in Chrome scans bar code that downloads a PDF file to display in browser.

2nd MC40 returns  " Nothing found " message

 

If I connect an external scanner the PDF file is shown as with 1st MC40

 

DATAWEDGE profile and configuration is the same for both devices

CHROME is the same version in both devices

 

Any one having this issue?   Thank you
