Hello, Mark,

thank you for your answers. Unfortunately it doesn't work that way either:

startup
...
drvAsynIPPortConfigure("MOXA_4", "172.24.192.29:4004", 0, 0, 0)
drvAsynKeithley648x("6485", "MOXA_4",0)
drvAsynKeithley648x::drvAsynKeithley6485 port MOXA_4 can't connect to asynCommon on Octet server 0 address 0.
asynSetTraceIOMask("MOXA_4", 0, 0x2)
asynSetTraceMask("MOXA_4", 0, 0x9)
dbLoadRecords("db/Keithley6485.db", "P=trARPES:, CA=Sample:, PORT=6485")
…

The driver is from https://github.com/dohnarms/epics-Keithley_648x

In the driver there seems to be a mismatch

…

/* Public interface forward references */
int drvAsynKeithley648x(const char* myport,const char* ioport, int ioaddr);
…

/****************************************************************************
 * Define public interface methods
 ****************************************************************************/
int drvAsynKeithley648x(const char *type, const char *myport,
                        const char *ioport, int ioaddr)
{
  int status = asynSuccess;
  Port* pport;
  //  int i;
  asynStandardInterfaces *pInterfaces;

  char inpBuf[BUFFER_SIZE];
  int eomReason;

  pport = (Port*)callocMustSucceed(1,sizeof(Port),"drvAsynKeithley6485”);

…

/****************************************************************************
 * Register public methods
 ****************************************************************************/

/* Initialization method definitions */
static const iocshArg arg0 = {"type",iocshArgString};
static const iocshArg arg1 = {"myport",iocshArgString};
static const iocshArg arg2 = {"ioport",iocshArgString};
static const iocshArg arg3 = {"ioaddr",iocshArgInt};
static const iocshArg* args[]= {&arg0,&arg1,&arg2,&arg3};
static const iocshFuncDef drvAsynKeithley648xFuncDef =
  {"drvAsynKeithley648x",4,args};
static void drvAsynKeithley648xCallFunc(const iocshArgBuf* args)
{
  drvAsynKeithley648x(args[0].sval,args[1].sval,args[2].sval,args[3].ival);
}

/* Registration method */
static void drvAsynKeithley648xRegister(void)
{
  static int firstTime = 1;

  if( firstTime )
    {
      firstTime = 0;
      iocshRegister( &drvAsynKeithley648xFuncDef,drvAsynKeithley648xCallFunc );
    }
}
epicsExportRegistrar( drvAsynKeithley648xRegister );

That is why I have given four arguments in the st.cmd.

Danke,
Heinz
