Dp8k update from Roadhog4; dmx outlets on Dp8k stop working


Today I ran a setup with a Roadhog4 and a blue Dp8K in a session. The internal Dp8k of the Roadhog wasn't used and therefore switched off. Since the Dp8k wasn't used for a while it had software version 3.9.0 running (which worked perfectly the last time I used it). The Roadhog runs software 3.13.1 so I needed to update the Dp8k. I used the network update functionality which seemed to work perfectly however the dmx outlets on the Dp8k stopped working after the update, there was no way of getting DMX out of the ports. I got the rig working by attaching a artnet node to the Dp8k which saved me for the day.  Before rehearsals I called a few collegeas to check if they had this problem before and one of them suggested to update the Dp8k thru a usb stick. After rehearsals I tried using a usb stick to update the Dp8k which have solved the problem, the outputs are now working again. 

Is this a known bug?

    Yes. This could have happened if you did an upgrade by pressing "Upgrade Nodes" instead of doing a net-boot or a doing a full install via USB. https://support.etcconnect.com/HES/Consoles/Hog_4/Hardware/DP_8000_does_not_output_DMX_from_the_ports_after_updating

    Mainly is you skipped versions from 3.9.0 to 3.12 or later.

    Hi Maegan, Thanks for your reply, I indeed did skip a few versions, however the suggested net-boot did not work for me, the DP didn't complete the installation at all and got stuck in some kind of update loop. Only way to break that loop was to pull the cord and do a usb update. After the usb update everything worked as expected. I had a unmanaged switch between the DP and the Roadhog, could that be the problem for the net-boot loop? The whole setup works perfect in show situation, cables are tested again today, no bad cables found. Max cable length 25 meter Cat6
