ESDVery wary of having procedures in place for ESD protection for module assembly and testingFor both roomsFor all parts of the build and assembly process

There is no point in having ESD floors if other ESD procedures are not carried through withMuch like cleanliness Andy Blue

ESD Grounding Wrist Strap

Attaches to wrist of user

Our system is 1 wrist strap / cleanroom userAnd not 1 /stationEach user is responsible for their own wrist strapAndy Blue

Compilation + ROOTNext step is to control via SCTDAQ (ROOT)When compiling sctdaq_HSIOAdd Existing project./sctdaq/interlock/tilokl.vcproj

Compile as usualShould produce a ./sctdaq/interlock/tilockdll__/ folderAlso creates .dll files in ./sctdaq/bin

From ROOTRun gSystem.Load(./sctdaq/bin/tilockdll.dll")This initiates the TILock class

locker = new TILock("ASRL**::INSTR")** =number of COM port USB cable is attached toIn my case it was locker = new TILock("ASRL4::INSTR")

Began to integrate into RootLogin.C
