Problem with IMAQdx and Pleora GigE Devices

Question

We have an iPort Analog Pro Pleora device to convert analog camera output to GigE. Our old camera works properly using the manufacturer's application "GEV". Images are displayed without problem and any packet size works fine.
Using NI-MAX the device is found and configured properly, but trying to get images the following message appear:
"the system did not receive a test packet from the camera. The packet size may be too large for the network config or a firewall may be enabled".
Firewall has been disabled and several packet sizes tested, but no images received. Manufacturer said that: "I know that NI IMAQ-dx does not have multi channel support, you can stream from the first channel but what happens is when NI caches the XML file upon connection, it reads the SourceSelector register and defaults it to Source2. You have to manually change the XML file to read Source1 for the SourceSelector or you can change this in the IMAQ software itself." This is true, but modifiyng the icd file for the first channel, nothing happens.
Also, some old messages about a similar problem with the Pleora's devices recommended to set the package' size to 1400. Again, nothing happens.
Any piece of advice about this problem (I know many people is working with pleora's device under NI-labview)?
Thanks in advance

Answer 1

For interested people:
1.- Select 1400 bytes packages
2.- Always select "Source 1"
and the most important thing:
3.- Select "Firewall Traversal - enabled"
And works.
