The decarads are talked to through a DB9 connector connected to a Digi Portserver. The software uses EPICS ASYN and Stream Device to send the commands to set the HV, read back the measurements, etc. The software is part of the RadiationMonitoring slac epics package. The source code can be reached from a development machine (currently afs): cd $EPICS_IOC_TOP/RadiationMonitoring. The database code is in RadiationMonitoringApp/Db/common in three files: decaradChannel.template, decaradCommon.template, decarad.substitutions. The file with the read/write commands is RadiationMonitoring/protocols/decarad.proto. The startup files are in iocBoot/sioc-sys0-rm01. The ioc status & control can be seen from LCLShome, SC gun, Network/Global under RadiationMonitoring sioc-sys0-rm01. The IP addresses are ts-sys0-nw01 and -nw02.
