QuantAsylum QA451 User’s Manual
Page 11
If this message appears, the application can still be used for manual control of the hardware, but remote
access won’t be possible.
If the message does not appear, then it means the server successfully started. The server responds to a
very limited set of commands and does not serve files or data. You can see the REST API published by
the QA451 by going to your browser and opening the url (the same URL is used for the QA450 and
QA451):
The browser should display a page outlining the QA451
REST API. If it does not and you aren’t seeing the
failure message above in the application status bar, then it might mean that you have a security
application or firewall blocking port 9450.
If you are sure that the firewall on your machine has port 9450 opened, then run the QA451 application
with admin rights and see if that allows a browser to open the link above. If that solves the problem,
then you can either run the app with admin rights when you want to enable the REST API, or you can
enable the port generally using a command line solution. To do this, open a command prompt with
admin privileges and type the following:
netsh http add urlacl url=http://*:9450/ user=DOMAIN\\user
Replace the ‘DOMAIN’ and ‘user’ text with the appropriate
domain and user name for your account. To
find your domain name, open the control panel, selection “System and Security” then “System” and
your will see an entry showing the Full Computer Name.
If you want to see what existing reservations are present on your machine (which should also give a clue
about the domain and user settings on your machine for other ports), then you can type:
netsh http show urlacl
To later remove the permission added above, you would enter:
netsh http delete urlacl url=http://*:9450/
