Hi Kaz,

Ø Camera Manta G-125B

Ø S/N: xxxxx

Ø Firmware: 00.01.44.18241

Ø SDK: 1.26

Ø Driver: 2.5.0

Ø ADCore: 3.5.0

None of that should matter.

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

That is not relevant to pvAccess.

Ø Aug 13, 2020 4:59:34 PM org.epics.pvaccess.client.impl.remote.ClientContextImpl getTransport

Ø SEVERE: Failed to create transport for: /10.10.0.2:48464

Ø org.epics.pvaccess.impl.remote.ConnectionException: Failed to connect to '/10.10.0.2:48464'.

Ø Aug 13, 2020 4:59:34 PM org.epics.pvaccess.client.impl.remote.ClientContextImpl getTransport

Ø SEVERE: Failed to create transport for: /10.10.1.3:48464

Ø org.epics.pvaccess.impl.remote.ConnectionException: Failed to connect to '/10.10.1.3:48464'.

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

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

What is at IP addresses 10.10.0.2 and 10.10.1.3?

Mark

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>]
