Hi Michael,

The problem is coming in the call to AndorCCD::setupShutter. This is called from the AndorCCD constructor as follows:

status |= setupShutter(-1);

If it returns an error then the constructor will fail, and you will get the errors you see. So we need to figure out why AndorCCD::setupShutter is failing.

This is the code:

/** Controls shutter

* @param[in] command 0=close, 1=open, -1=no change, only set other parameters */

asynStatus AndorCCD::setupShutter(int command)

{

double dTemp;

int openTime, closeTime;

int shutterExTTL;

int shutterMode;

asynStatus status=asynSuccess;

static const char *functionName = "setupShutter";

getDoubleParam(ADShutterOpenDelay, &dTemp);

// Convert to ms

openTime = (int)(dTemp * 1000.);

getDoubleParam(ADShutterCloseDelay, &dTemp);

closeTime = (int)(dTemp * 1000.);

getIntegerParam(AndorShutterMode, &shutterMode);

getIntegerParam(AndorShutterExTTL, &shutterExTTL);

if (command == ADShutterClosed) {

shutterMode = AShutterClose;

setIntegerParam(ADShutterStatus, ADShutterClosed);

}

else if (command == ADShutterOpen) {

if (shutterMode == AShutterOpen) {

setIntegerParam(ADShutterStatus, ADShutterOpen);

}

// No need to change shutterMode, we leave it alone and it shutter

// will do correct thing, i.e. auto or open depending shutterMode

}

try {

asynPrint(this->pasynUserSelf, ASYN_TRACE_FLOW,

"%s:%s:, SetShutter(%d,%d,%d,%d)\n",

driverName, functionName, shutterExTTL, shutterMode, closeTime, openTime);

checkStatus(SetShutter(shutterExTTL, shutterMode, closeTime, openTime));

} catch (const std::string &e) {

asynPrint(pasynUserSelf, ASYN_TRACE_ERROR,

"%s:%s: %s\n",

driverName, functionName, e.c_str());

status = asynError;

}

return status;

}

This is the error you are getting:

2016/01/04 15:25:05.348 andorCCD:setupShutter: ERROR: Parameter 3 not valid.

So the error is coming in the call to the Andor vendor library function SetShutter(), and the error is "Parameter 3 not valid". Parameter 3 is closeTime. So it appears that an invalid value for closeTime is being passed. closeTime is the value of the ADShutterCloseDelay parameter, converted to milliseconds. ADShutterCloseDelay is defined by the following record in ADBase.template:

record(ao, "$(P)$(R)ShutterCloseDelay")

{

field(PINI, "YES")

field(DTYP, "asynFloat64")

field(OUT, "@asyn($(PORT),$(ADDR),$(TIMEOUT))SHUTTER_CLOSE_DELAY")

field(PREC, "3")

field(VAL, "0.0")

info(autosaveFields, "VAL")

}

So the default value is 0.0. Have you modified this record, or could there be a non-zero value in autosave?

You can see that there is an asynPrint() statement just before the call to SetShutter in the above function which will print the values of all of the arguments being passed to SetShutter(). It is a bit tricky to enable ASYN_TRACE_FLOW in the constructor, so the simplest thing to do is just change that asynPrint() statement to a printf(). Then you can see what value of closeTime is being passed to SetShutter(). Hopefully the documentation for your camera gives the valid range of closeTime, or else you can just experiment to find a valid value. Then you will need to create a new database that modifies the value of $(P)$(R)ShutterCloseDelay, or modify the one in ADCore/ADApp/Db/ADBase.template (which is probably not a good idea).

Subject: AreaDetector ADAndor - iXon Ultra 888

I'm having problems running ADAndor (R2-4) on RHEL6 64-bit (kernel

2.6.32-573.8.1.el6.x86_64) with an Andor iXon Ultra 888 USB 3.0 CCD.

I'm able to acquire an image with the Andor SDK (version 2.99.30000.1)

using their example programs, but I get the following when running

AreaDetector:
