Enttec ethergate artnet connection issue

[JonT]

Thanks Richard for your quick responses.

Unfortunately I did not manage to get ethergate to work with catalyst and had to sub-hire a Catalyst CIB (which worked fine).

However I did manage to run "tcpdump udp" on the PowerMac:
it showed a steady stream of packets to port 6454 (artnet) and none to 333 (proprietry procotol).
Unfortunately tcpdump (unlike ethereal) does not understand artnet and all I saw was strings of (non-zero) hex data.

I hope in the next weeks to get enough time (hah !) to install ethereal for MacOS and see what traffic is really there.

The thing is that bringing up the information window ('w') and stepping through to the page showing DMX details listed the ethergate as having universe 0, and it was sensitive cables disconnecting (so it wasn't historical "memory" of the ethergate).

thanks again.

i dont have one of these devices.
So i dont know what happens in the various modes.

There are many possible problems, from the box using a different ip universe, to it outputting wierd artnet.

You might like to try sending me the hex and ascii dump of a packet sent by the device - if you can get such a thing.

I think the shareware program' interarchy' does udp packet dumps?

Interarchy does indeed give you a dump of network traffic

It can give a text or binary display of udp or tcpip packets

I believe the Art-Net settings for this device are set onboard and not using the web-interface as this is not finished yet.

The Enttec box IS ArtNet compatible

The correct ethernet settings for artnet are:
2.0.0.x, subnet mask 255.0.0.y

or if you do not want your Artnet to be routable:
10.0.0.x, subnet mask 255.0.0.y

subnet mask should be 255.0.0.0

the manual said that artnet mode could only be enabled from the web interface. so its all a little confusing.

Havent received any kindof response as to whether this box even does artnet correctly yet!

Guys,

I just got off the phone with Jon in Australia.

He is having another go at getting this box working.

From what he described he is seeing non-zero values from the Hog 3 on his PC but the Catalyst is "seeing" the artnet universe (IP address is shown in the artnet status window and Artnet 0 is highlighted blue) but all values are at 0 in the window itself.

It sounds a bit like a problem I was having with the Ether-Lynx box itself recently.

On that occasion I had connection between the box and the Mac itself and PixelMad was outputting DMX. I could modify the image on PixelMad and output DMX to fixtures accordingly but it would not respond to an incoming DMX signal.

It seemed really odd it could "speak" art-net to the Lynx but not "hear" it as it obviously had a good TCP/IP connection.

I could also control PixelMad by connecting a CIB and then use the Lynx to output the DMX to the PixelLines as a workaround.

After trouble shooting with the ArtNet monitor software connected to an ethernet switch on the same network, it turned out to be because I had old firmware on the Ether Lynx box and once upgraded it worked fine.

It was Wayne I spoke to at Artistic so if he recalls the incident he may be able to suggest what differed between the builds.

Richard,

Do you have any ideas what this could have been?

Perhaps it is something that hasn't been implemented on the EtherGate which allows normal Artnet traffic but doesn't talk to Catalyst.

I've suggested Jon post back here with as much info as possible as many heads are better than one.
