You can also do the test without any dmx fixture.
There could not be any log because the interface hangs, so it simply does not usb answer.
The second usual problem (after ground loop problem), is the usb power.
In the meantime, please post your lightshow, and tell us your computer configuration.
We will reproduce same setup here and check, in case of this is a software bug.
Hi
Thanks for your response.
1) I understand and I start the sweet light software with D512 and without fixtures running some hours
2) In my oppinion in the case the fault exists, there is still a communication between sweetlight software and D512, because I get the message, that a wrong interface is connected. If there wouldn´t be a communication (interface is plugged off) I´ll get NO FAULT message. Perpahs it could be an improvement to implement a watchdog within D512 interface.
3) Do you think ground loop with only 15m DMX calbe can effect this fault? Do you have some further information according this? If there is a fixture for example LED Par where ground is connected to DMX ground, how can I solve this? Could it be an improfement, that on the side of D512 the ground will be lifted?
4) I´ll test with USB hub with external power. Probably an improvement according D512 could also be a watchdog funktionality, which restarts CPU in case of sporadic Power Issue.
5) Please see the attachment for the show. The Laptop is HP 6830s with windows XP, 2GB RAM (0,7GB RAM is used), 2 CPU (CPU usage is 4 to 20%). Performance is quiete good.
6) The situation on saturday 9.9.2017 was:
- sweetlight software was running. There was no change on the show
- DMX signal stopped. So the lights go off
- blue power LED on Interface was on
- green PC link LED was off
- shutdown and start of sweetlight software shows Error, wrong interface
- shutdown of sweetlight & plug off DMX Interface, plut in DMX interface and start sweetlight again and it worked correct for the next hours.
