SHOC
,===LED timing tests===
''This functionality should be available on the 74", the 40" and the new 1mLesedi. It has only been tested on the 74".''
The idea is to take a long, GPS-triggered data cube with SHOC at high cadence, while running the LED at 1 PPS (which has a longer pulse on the minute and can thus be used to test absolute timing accuracy).
*The dome and mirror covers must be OPEN for this test to work. (The GPS needs to get satellite signal, and the LED must be seen through the light path.)

Note that the '''shocnawe''' now points to '''shoc40in.suth.saao.ac.za'''. If it is configured like this, that means the '''shocnawe''' machine is in the '''40inch'''. When it is moved, '''only''' change the '''40''' to '''74''' like below:
'''Possible CNAME changes'''
With the CNAME setup below, both the shocndisbelief and shocnawe can be connected in the new '''1m'''Lesedi. Please ask the IT standby person to help you with this DNS setup. At this moment '''only''' the '''shocnawe''' will be moved between the 40inch and 74inch. The '''shocndisbelief''' is in the '''1m''' and will '''not''' Either SHOC instrument may be moved between mounted on any of the 40inch and 74inchthree telescopes.

==Run the shocboxswitch.sh script when SHOC is moved between telescopes==
Run the script shocboxswitch.sh. The default option reverts to the standard mapping between shoc SHOC computers and telescopes. If the default is not chosen , you'll be prompted for the name of the telescope the shoc 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:
** Check that the antenna cable has been connected to the SHOC GPS on the box.
** Check that the antenna has access to the sky (i.e. the dome is open)
** Check that the location settings are correct. Click on 'receiver status' in the GPS tab and look at the latitude and longitude. The Sutherland Latitude is ~32 22 S while Cape Town is 33 56S. If the location is not corrrectcorrect, then the GPS will not find satellites and the correct location needs to be updated as described in the Configuring SHOC section.
* Camera is in an inoperable state:
** Restart the services by sshing into the SHOC computer (see Configuring SHOC section):
