Outline

• Check connection details– Hardware manual

• Test/Debug command– Try simple command/response in text form

• Select commands to implement– Hardware manual

• Some examples– Set and read voltage/ formatted parsing

Connection details

• Check manual for information on:– RS223 parameters (baud, parity…)– TCP/IP name, port number– Command delimiters

Extract from manual

• From the Agilent N5700 manual:

Connection setup

• In the startup command file “stAg.cmd”

epicsEnvSet("STREAM_PROTOCOL_PATH", "/u/cbmdcs/apps/StreamTest/protocols”)## Register all support componentsdbLoadDatabase "dbd/hades.dbd"hades_registerRecordDeviceDriver pdbbasedrvAsynIPPortConfigure("ps001", ”hadps001.gsi.de:5025")## Load record instancesdbLoadRecords("db/Agilent1.db")

Record and protocol definition

• In record database file (Agilent1.db):record(stringout, "HAD:MDC:PS:01:DEBUG") { field(DESC, "Debuging help") field(DTYP, "stream") field(SCAN, "Passive") field(OUT, ”@Agilent.proto debug ps001 ") field(ASG, "mdc")}

• In protocol file (Agilent.proto):Terminator = LF; # After processing finishes, the record contains the reply.debug {ExtraInput = Ignore; out "%s"; in "%39c”;}
