Hi Peter, Regarding your questionsOn Fri, Mar 17, 2017 at 10:13 AM, Heesterman, Peter J <[email protected]> wrote:
Yes, you are correct.
It is a typo.
"cam1:" refers to PV's that control the camera itself: starting / stopping the acquisition, setting the exposure time, etc. "image1:" PV's are for the NDStdArrays plugin, which converts the internal NDArray representation used by areaDetector into a waveform that EPICS clients can understand. Of course, you can choose whatever prefixes you want, but those are kind of standard. What kind of error do you get if you leave the NDStdArrays prefix as "image1:"?
As Ralph said, check that the environment variable EPICS_CA_MAX_ARRAY_BYTES is adequate. It should be larger than the largest image you intend to transfer. You could check if caget complains if you try to read the PV 13URL1:image1:ArrayData HTH, Bruno
