pvget does not need to be available to use ImageJ.

Did you install all of the latest .jar files from ADViewers as well?

The first thing to test is to see if it is a problem with the Java PVA client used in ImageJ.  Does pvget work to read the NTNDArray on the same computer that is running ImageJ?

Hi Mark,

The 10.10.2.4, and 10.10.1.3 are ioc server interfaces where camera ioc is running.

I have never seen these errors either with old-old version of PvA plugin that runs on other workstations.

None of that should matter.

That is not relevant to pvAccess.

I have never seen errors like those, so I don’t know what could be wrong.

What is at IP addresses 10.10.0.2 and 10.10.1.3?

Camera Manta G-125B

S/N: xxxxx

Firmware: 00.01.44.18241

SDK: 1.26

Driver: 2.5.0

ADCore: 3.5.0

OS (client where imagej is running): Debian 10

OS (EPICS ioc server): Debian 7

imagej debian version:

```

kgofron@xf10id-ws1:~$ dpkg -l | grep imagej

ii  imagej                                        1.52j-1                                      all          Image processing program with a focus on microscopy images

```
==================

I just cloned the master version of imagej viewers, and 'EPICS_AD Viewer' CA version works fine, but the 'EPICS_NTNDA_VIEWER' PVA version does not connect. Am I missing something?

My EPICS VLAN interfaces are on 10.10.0.x, and interfaces 10.10.1.y are for direct access to webcams.

In the same time CSS opi displays PvA images correctly.

========

kgofron@xf10id-ws1:~$ export EPICS_CA_MAX_ARRAY_BYTES=6000000

kgofron@xf10id-ws1:~$ imagej

Open other images in this ImageJ panel as follows:

  imagej -p 1 <image1> [<image2> ... <imageN>]
