• Problems to start DAQ

One of the most common reasons why the S800 DAQ fails to start is because the CCUSB and/or VMUSB are claimed by existing programs. This is shown by the error messages displayed by the system. If you find yourself in this situation try the following:

1. Log on to S800 spdaq (spdaq19 as of October 2015)
2. Type ps aux | grep Readout
3. Use kill -9 PID, where PID identifies any CCUSBReadout or VMUSBReadout processes that show up
4. Use kill -9 PID, where PID identifies any tclsh ReadoutShell process that might show up
5. Try godaq to see if this works now
