Hello Hillmann,
The monitor page not showing any DMX output kind of indicates already that something is not setup right in the B-station. Assuming that you followed the manual for connecting the physical DMX cable, I would assume that this is connected right. To help you I need a little bit more info on how the setup is of the B-Station.
Could you tell me, in the web browser, if you select the cue in the cuelist, are the fixtures selected (the checkbox in the topright of the fixtures are set). If so, did you check whether some fader is open? Is a cuelist with content playing? And finally, which firmware version are you using?
Thanks,
Jurrien
