Configuration

The XPS-C8 is accessible via ethernet and resides in the local X1A subnet (see our website for network info). It offers an HTTP server as well as an FTP server. A logged in Administrator can change the configuration. The two main configuration files are CONFIG/stages.ini, which contains technical specifications of all stages in use, and CONFIG/system.ini, telling what stage is connected to which driver slot and the names under which they are known. Copies of these files configured to our needs are in cvs/src/stxm5/newport. The unit we have chosen in system.ini is mm for all stages. The unit internally used by the XPS is encoder pulses. The unit shown externally can be freely chosen by the entry EncoderResolution and has to be used consistently for all other entries in stages.ini. (It would make sense for us to choose the unit as $\mu$m. But the XPS' remote control cannot handle positions outside of $\pm 2147.483647$ (long signed integer / $10^6$). So on the remote control and the web interface, positions will be given in mm. This requires some caution by the user!)

There are two ways to change the XPS configuration. You can edit the two files on your local computer, then upload them via FTP to the XPS and reboot. Or you can use the XPS' web interface from any web browser of your choice. There you can also change additional things as the IP configuration, add users, change passwords etc. Using the web interface is fairly intuitive and further info can be found in the XPS manual. How to move motors over the web interface is described in the STXM5 User Manual.
