Log into the host machine and start up an RCE GUI...at CERN:
the host machine is: pddaq-gen02-ctrl0gen03
the software lives at: /daq/rce/proto-dune/software.pd/protoDUNE
start the gui with: /daq/rce/proto-dune/software.pd/protoDUNE/rceScripts/rce_talk CERN-100 start_gui
From the GUI, hit the HardReset button...this sets everything to a known state
Go to the configuration tab, and set the following values:
DataDpmEmu>EnableTx>True
DataDpmHlsMon>Blowoff>0x1 (or 0x2, this blows off either WIB0 or WIB1...without compression, we can't DMA both at same time)
DataDpmTiming>SwFlush>False
DataDpmWib>RxPolarity>True
If you want to run in emulation mode (e.g. if you don't have a WIB hooked up), also set:
DataDpmEmu>Loopback>True
Hit the "Write Configuration" button:
That's it...you should be receiving data to the DataBuffer...you can tell by going to the "Status" tab...should look something like this:
note there is no Tx since we haven't hooked up a receiver from the host PC to the RCE...data is just getting dropped on the floor by the DataBuffer software at this point
You can also look at the WIB-RCE-receiver piece (before data gets aggregated/framed/DMAed and send to software side)...should look like this:
