Run the script shocboxswitch.sh. The default option reverts to the standard mapping between shoc computers and telescopes. If the default is not chosen , you'll be prompted for the name of the telescope the shoc computer is being mounted on.
* Check the log entry to make sure the configuration was changed to the telescope you chose. In a terminal type:
less /var/log/shoc-camera.log
