Trunker Posted January 23, 2009 Share Posted January 23, 2009 Being a novice on scrollers here is most probably an easy question for you to answer. I am using a Bull Frog lx board and have set the scrollers to channels 300 and 350 repectively. The scrollers are not responding. I have patched them in as a fixture as a 1 channel scroller. Everything else in the DMX chain is working so I don't think its a lead issue. Can't tell you what scrollers they are sorry, but I assume scrollers are very similar in the set-up respect. Can anyone help? Cheers Link to comment Share on other sites More sharing options...

How many scrollers are you using? If you are using a large number then you might have to loop the scroller cable back to the PSU. Link to comment Share on other sites More sharing options...
Trunker Posted January 23, 2009 Author Share Posted January 23, 2009 Yep, done all those. Only using 2 scrollers, so I don't think there would be an issue with the psu!? They come on go through the scroll cycle then the board cannot seem to talk to them. Is there anything in the set-up menu on the scrollers I should do?

gherriott Posted January 23, 2009 Share Posted January 23, 2009 Are the scrollers receiving DMX? You should have a green light or something lit both on each scroller and on the PSU if so? Link to comment Share on other sites More sharing options...

Hmmm I suppose you have checked that these are single channel scrollers? Although I cant think of any that aren't.It seems that you are not getting a DMX feed, can you see a green light on the scrollers this normally indicates DMX. Next I would recheck that the DMX address on the scrollers is correct. and that you have patched the right address into the board. Link to comment Share on other sites More sharing options...

Trunker Posted January 23, 2009 Author Share Posted January 23, 2009 Yes, I believe they were, I had loads to do today, so can't exactly remember. If they are should they automatically work? or should you have to adjust the menu in some way? Link to comment Share on other sites More sharing options...

Yes if the right address has been patched into the board as soon as you light up their buttons and press colour they should respond to the wheel.

Trunker Posted January 23, 2009 Author Share Posted January 23, 2009 Thanks mate your a star. If they are reversed polarity what is the best thing to do? I have hired the scroolers and the leads, so they should be compatable!? Am I wrong in thinking this? PS I did hire them from the same company, ** laughs out loud **.

niclights Posted January 23, 2009 Share Posted January 23, 2009 It's about compatibility with the controller, rather than related to the cables, which would all be the same. Best to determine if they are receiving DMX or not before worrying about reversing polarity. If you knew which scrollers then it would be easy to check.

Trunker Posted January 24, 2009 Author Share Posted January 24, 2009 Not really sure what the scrollers are tbh. Not vey helpful I know. Sorry Link to comment Share on other sites More sharing options...
paulears Posted January 24, 2009 Share Posted January 24, 2009 If the desk is set up so that it thinks it's talking to a single channel dimmer, the cables are connected and control signals are getting to the units, then the remaining problem area could just be that you've mis-addressed them. I'm not sure how easy it is to do on a Frog - never having ever touched one - but a 1 to 1 patch across all 512 channel, stuck on a fader would let you raise and lower every DMX channel at the same time. I've found this handy when trying to sort problems in the past, as every light will start to come on, and movers start to move and scrollers will scroll. Anything that doesn't has a problem at it's end, not the control. If you know the DMX route from fixture to fixture you can also use it to see where control signals stop, or where a fixture is ignoring them. If you can do this, then it will show you instantly if the problem is in addressing - as in they start to scroll, but if they don't then you just look at the next fixture on that line and if that's responding, then the scroller is Kaput!

Trunker Posted January 24, 2009 Author Share Posted January 24, 2009 Ah OK will set the scroller up on fader 90 and see if that works. Cheers EDIT Spelling not good this morning Link to comment Share on other sites More sharing options...
tom_the_LD Posted January 24, 2009 Share Posted January 24, 2009 This may seem daft but I'm going to try anyway! I asume that you have connected the PSU into the DMX Chain!? Something else to try - it could be your addressing is wrong. It might be worth addressing them to something like 333 and 444 that way, if they are on rotary switches, you can't go far wrong! Obviously if you are on DIP's this wouldn't be as helpful/appropriate. Like Paul says the best thing to do now would be to try and map the scroller address channel to a fader. Let us know!
