toby Posted May 9, 2005 Share Posted May 9, 2005 right a quick question which I hit me earlier, im doing a show coming up. VERY small scale, literally 2 x Mini Macs(for the ability of being able to use a 13 amp supply) and a fat frog control desk(I love it) and I realised if I am only using 2 moving lights do I need to hire a DMX as well. if someone could let me know. cheerstoby Link to comment Share on other sites More sharing options...
gareth Posted May 9, 2005 Share Posted May 9, 2005 A DMX? What do you mean? DMX isn't a physical 'thing' - it's a control data protocol (DMX512). Moderation - moved post into the correct forum. Lighting questions go in the Lighting forum. Link to comment Share on other sites More sharing options...
Darkfold Posted May 9, 2005 Share Posted May 9, 2005 Using fat frog desk, (a DMX desk...) and 2 x Mini Macs (DMX lights), yes, I'd say you need DMX...Go read this... Link to comment Share on other sites More sharing options...
sigill Posted May 9, 2005 Share Posted May 9, 2005 Hi Not quite sure what you mean by "A" DMX. DMX is not an object it is a protocol for sending instructions to dimmers or intelligent lights from a lighting control desk. The frog desk already uses this protocol. On the back of the desk you will find a 5 pin output labeled DMX out. Run a cable from this to mini mac 1 then out of mini mac 1 into mini mac 2. I am assuming that you know how to address these and how to patch them in the desk. If you are using generics as well you should find a DMX out on your dimmers connect you macs to this in the same way. Link to comment Share on other sites More sharing options...
Freddie Posted May 9, 2005 Share Posted May 9, 2005 Maybe a DeMuX? (Short for Demultiplexer by the way, it converts Digital DMX signals to +/-10V analogue signals for control of old dimmers). If it's just a FF then 2 macs, you won't need one. If you mean DMX-A, I have no idea. I think it's a future plan for the other 2 pins in a 5pin XLR.

sam.henderson Posted May 10, 2005 Share Posted May 10, 2005 Where did DMX-A and a Demux come into the equation, lets not confuse the poor guy!! Yes you will need a DMX system (which is what I presume you mean) to connect the movers to the desk. So you will have a 5 pin out of the desk into --> 5pin to 3pin convertor into --> Minimac 1 out to --> Mini Mac two --> into a DMX terminator.

Bryson Posted May 10, 2005 Share Posted May 10, 2005 I think it's quite possible that the OP meant a Demux, judging by the general level of knowledge implied (no insult, just an observation). DMX-A might be stretching it a bit, I agree. Hey, from the age of 15 to the age of 18, I thought they were called Parkhands! (True Story) Link to comment Share on other sites More sharing options...
DSA Posted May 10, 2005 Share Posted May 10, 2005 Hey, from the age of 15 to the age of 18, I thought they were called Parkhands! (True Story)For a similar length of time, I thought it was Fres-nels. Until someone corrected me that is! I think its likely too that he meant Demux. Just thinking of the number of phone conversations I have had when you mishear things like that. Seems highly likely that it was a 'word of mouth translation' perhaps? David Link to comment Share on other sites More sharing options...
andy jackson Posted May 10, 2005 Share Posted May 10, 2005 DMX-A? then at least it could give you some feedback on whats happening! Link to comment Share on other sites More sharing options...
Darkfold Posted May 10, 2005 Share Posted May 10, 2005 A DeMuX would only be required if the power packs were analogue. He mentions no powerpacks (13 amp mains used), therefore a DeMux is not required. Link to comment Share on other sites More sharing options...
Tomo Posted May 10, 2005 Share Posted May 10, 2005 right a quick question which I hit me earlier, im doing a show coming up. VERY small scale, literally 2 x Mini Macs(for the ability of being able to use a 13 amp supply) and a fat frog control desk(I love it) and I realised if I am only using 2 moving lights do I need to hire a DMX as well. if someone could let me know. cheerstoby<{POST_SNAPBACK}> Here's EXACTLY what you need to run two Mini Macs using a Fat Frog:(If you want to run anything else you'll need extra stuff) Extension leads from your power source (13A wall sockets) to each of your minimacs. Extension leads from power to your Fat Frog (and any other bits like monitors). 2x pieces of 3-pin DMX cable - one to go from your Fat Frog to the first Mini Mac, and another to go from the 1st to the 2nd Mini Mac. 1x 5 to 3-pin DMX adapter to plug into the back of your Fat Frog. 1x 3-pin DMX terminator to go in the DMX-out of the last Mini Mac.(Thanks Darkfold) Link to comment Share on other sites More sharing options...
Darkfold Posted May 10, 2005 Share Posted May 10, 2005 missed a bit in that post. A (one) DMX line terminator unless theres an inbuilt one on the last minimac. Link to comment Share on other sites More sharing options...
sam.henderson Posted May 10, 2005 Share Posted May 10, 2005 No, AFAIK non of the martin mac range have an inbuilt termination. Sam Link to comment Share on other sites More sharing options...
