 In the rare case that the RunControl GUI gets "frozen", it is possible to reboot the whole system manually. This operation requires to turn off the VME and CAMAC crates, and the spdaq computer, all them located in the rack seating near the FP box in the S3 vault. Then, the system must be turned back on in the following order. First, CAMAC crate, second VME crate, and third spdaq. In the rare case that the RunControl GUI gets "frozen", it is possible to reboot the whole system manually.

-===== S800 DAQ status tool ===== 
-In order to remotely monitor the status of the S800 DAQ, a tool has been created which can show statistics and current information about the present running instances of the Readout GUI and eventbuilder programs. This is accessed by the following: 
- 
-1. On spdaq48 do: 
- 
-**/user/s800/operations/daq/usb/s800status/comms** 
- 
-which will open the status GUI. 
- 
-There are tabs for connections to the Readout GUI, the eventbuilder and a controls tab. 
- 
- 
-==== Readout GUI tab ==== 
-The communications port to the Readout GUI is tcp:7999 and it runs by default on spdaq48. These options are selected by default in the server and port drop down boxes, but other values can be entered here by hand. Clicking "Get Status" will connect to this server/port combination and attempt to fill in the Run Info section with the returned information. The status will also be updated.

 If the eventbuilder is hanging, which is evidenced by non-increasing statistics and no data/triggers, then it is possible that one of these processes has crashed in a manner that holds open the tcp connection to the eventbuilder. The process can be killed, which will return the DAQ to a normal running mode. If the eventbuilder is hanging, which is evidenced by non-increasing statistics and no data/triggers, then it is possible that one of these processes has crashed in a manner that holds open the tcp connection to the eventbuilder.

-==== Controls tab ==== 
-This tab allows forced control of the Readout GUI, and is for advanced users only. In the event that the run must be stopped, or the DAQ software exited without access to the Readout GUI itself these buttons may be used to perform these actions. The run MUST be ended before using the Force Exit button, or it is likely that the USB crate controllers will become stuck in DAQ mode and the crates will have to be reset.
