- (decision) we put a dedicated daq evr in the controls plc node or controls evr node or drp/ctl node?
- evr gets driven by xpm fiber so trigger stops on endrun
- ttl cable to plc
- both evr and plc use BNC connectors 
- drp executable joins udp packet to timestamp from kcu (reuses TDetSim firmware).  It is new UdpDetectorUdpEncoder, which inherits from XpmDetector (Detector Class Diagram)
- (decision) question: do we have udp direct connection or go through the router?  router is easier, but could drop the first packet and be off-by-one (can’t detect off by one with dropped shots). direct? cpo feels we should avoid the router.
- “direct” may mean a switch where we control the traffic?  (ATCA (8 sfp, 8 rj45) or top-of-rack with a new vlan?) could use it for xtcav as well.
- ready "early march”
- clearreadout means:  kcu clears its fifos, drp clears out UDP packets on configure/endrun
- ric idea: IF we could send out 1 trigger on beginrun then we could use that as the starting for future frame counters to detect a missing first packet.  not clear how to send that 1 trigger.
