Hi,
 
I have been working with AreaDetector and the URL driver.
This is aimed at providing a training module that uses an IP camera.
 
I’ve been working with release R1-9-1 (I believe this is the newest of the 1.x releases), using medm and the EPICS AD Viewer plugin of ImageJ.
I’m working with an Ubuntu /x64 14.04.3 in a VM.
I have GraphicsMagick 1.3.18.
 
However, I think my questions remain pertinent to release R2-5.
 
Questions:
 
1. In start_epics, I suspect that:
 
        medm -x -macro "P=13SIM1:, R=cam1:" simDetector.adl & is meant to be:
 
        medm -x -macro "P=13URL1:, R=cam1:" URLDriver.adl &
 
2. In st.cmd, in the line:
        {URLDriverConfig("$(PORT)", 0, 0)
 
    Is the brace character intended, or is a typo?
 
    I can make it work if the brace is removed.
 
3.  In st.cmd, some lines refer to R=cam1:, whereas some lines refer to R=image1:, is this intended?
     e.g.
        dbLoadRecords("$(ADURL)/db/URLDriver.template","P=$(PREFIX),R=cam1:,PORT=$(PORT),ADDR=0,TIMEOUT=1")
     and
        dbLoadRecords("$(ADCORE)/db/NDStdArrays.template", "P=$(PREFIX),R=image1:,PORT=Image1,ADDR=0,TIMEOUT=1,NDARRAY_PORT=$(PORT),TYPE=Int8,FTVL=UCHAR,NELEMENTS=12582912")
 
     I can make it work if I change R=image1: to R=cam1:
 
4. In auto_settings.req some lines refer to R=cam1:, and some refer to R=image1:, is this intended?
 
    Again, I can make it work if I change R=image1: to R=cam1:
 
5. The issue I haven’t been able to resolve is this (see screen shot):
 
I believe the software is correctly collecting image data frames, and the ImageJ plugin shows green with correct connection.
 
But – I don’t see any picture...
What could I be missing here?
 
I note that the “Colour mode” is Mono, where the camera has colour.
I also tried this with images/sun.jpg, which is definitely a colour picture.
 
I’ve referred to resources like http://cars.uchicago.edu/software/epics/URLDriverDoc.html and http://cars.uchicago.edu/software/epics/areaDetectorViewers.html for information.
 
Many thanks for help received,
 
Peter.
