I looked at this more closely.

drvAsynIPPortConfigure("MOXA_4", "172.24.192.29:4004", 0, 0, 0)
asynOctetConnect("KeithleyIO", "MOXA_4", "-1",2000)
drvAsynKeithley648x("6485", "MOXA_4","KeithleyIO",0)
asynSetTraceIOMask("MOXA_4", 0, 0x2)
asynSetTraceMask("MOXA_4", 0, 0x9)
dbLoadRecords("db/Keithley6485.db", "P=trARPES:, CA=Sample:, PORT=MOXA_4")

My comments are:
Your original message says that drvAsynKeithley6845 take 3 arguments.  Your actual commands call drvAsynKeithey648x with 4 arguments.  Why the difference?  Does 648x take an initial argument with the exact model number, or is that the name of the new port?

I don't see the need for the asynOctetConnect line.

Maybe this will work:

drvAsynIPPortConfigure("MOXA_4", "172.24.192.29:4004", 0, 0, 0)
drvAsynKeithley648x("6485", "MOXA_4",0)
asynSetTraceIOMask("MOXA_4", 0, 0x2)
asynSetTraceMask("MOXA_4", 0, 0x9)
dbLoadRecords("db/Keithley6485.db", "P=trARPES:, CA=Sample:, "6845")

I deleted the asynOctetConnect, deleted the 3 argument to drvKeithley648x, and changed the port passed in dbLoadRecords.

Is this driver code on Github or somewhere else we can look at it?

Hi Heinz,

I am not sure, but this line looks wrong to me:

> dbLoadRecords("db/Keithley6485.db", "P=trARPES:, CA=Sample:, PORT=MOXA_4")

It seems that should probably be:

dbLoadRecords("db/Keithley6485.db", "P=trARPES:, CA=Sample:, PORT=KeithleyIO")

The PORT that database talks to is the KeithleyIO, not the underlying TCP port?

I want to use the ip-driver for the Keithley 6485:

/*
 Description
    This module provides support for a multiple device port driver. To
    initialize the driver, the method drvAsynKeithley6485() is called from the
    startup script with the following calling sequence.

        drvAsynKeithley6485(myport,ioport,ioaddr)

        Where:
            myport - Keithley6485 Asyn interface port driver name (i.e. "EP0" )
            ioport - Communication port driver name (i.e. "S0" )
            ioaddr - Communication port device addr

    The method dbior can be called from the IOC shell to display the current
    status of the driver.
*/

Unfortunately I don't know how to configure the "ioport".

Right now, here's what I'm gonna try in the st.cmd:

drvAsynIPPortConfigure("MOXA_4", "172.24.192.29:4004", 0, 0, 0)
asynOctetConnect("KeithleyIO", "MOXA_4", "-1",2000)
drvAsynKeithley648x("6485", "MOXA_4","KeithleyIO",0)
asynSetTraceIOMask("MOXA_4", 0, 0x2)
asynSetTraceMask("MOXA_4", 0, 0x9)
dbLoadRecords("db/Keithley6485.db", "P=trARPES:, CA=Sample:, PORT=MOXA_4")

Unfortunately there is no communication with the device.
How do I configure this correctly?

Danke,
Heinz
