quED Controller
6 Controlling the quCR via Ethernet
Some functionalities of the quCR can also be used over the network. If the quCR is
connected to a DHCP device (such as a router), the assigned IP address will show in the
Info tab (see Sec.
). With that, you can both open a VNC connection or control
some functionalities of the quCR remotely by HTTP.
6.1 Open a VNC connection
To open a VNC connection (to, e.g., display the quCR screen on a big screen or beamer),
type in the IP adress of the quCR into your VNC software (VNC Viewer for Windows is
free and works ne). If prompted for a password, use qut00lsMUNICH. You will then
get access to the screen of the quCR and all its functionalities.
6.2 HTTP Interface
The quCR can also be controlled via HTTP. For that, build the URL like this:
http://<ipaddress>:8080/?action=<action>¶m=<parameter><&value=<value>>
Valid actions are "`get"' and "`set"', valid parameters are:
"`ild"': Laser diode current (set and get)
"`pm1"', "`pm2"': Motor positions 1 and 2 (set only, in degrees)
"`int"': Integration time in ms (set and get)
"`cnt"': Get Countrates (get only)
"`mref"': recalibrate motor <value> (set only)
For example, you can get all countrates by requesting the URL
http://192.168.1.23:8080/?action=get¶m=cnt
The motor position of the rst motor could be set by
http://192.168.1.23:8080/?action=set¶m=pm1&value=22.5
