Ole Sundsby Posted January 25, 2009 Share Posted January 25, 2009 Hi all, About to buy myself a battery/charger for my Arriflex 2c here: http://www.batteryspace.com/index.asp?Page...amp;ProdID=2014 However, the interesting thing is that I obviously need to know which of the 5 pins from the xlr that connects to the poles on the battery (+/-). Does anyone here have a diagram showing which pin is + and which is - ? Any help would be greatly appreciated! Kind Regards, Ole Link to comment Share on other sites More sharing options...
Chad Mayer Posted January 26, 2009 Share Posted January 26, 2009 Hi Ole, I'm planning on buying the same battery from the same place! I've got their charger already on order. I'm not sure what you mean by XLR because the Arriflex power connections are typically just two pins, their own type of connector. (I believe) Did you or a previous owner adapt an XLR to the IIC motor connector/cable? My battery connection had been changed to an XLR and I used a continuity tester on a multimeter to determine which of the XLR pins were being used for +/-. The specific XLR pins used were whichever ones the person who modified it decided to use. Or maybe I'm completely misinterpreting your question, -Chad Hi all, About to buy myself a battery/charger for my Arriflex 2c here: http://www.batteryspace.com/index.asp?Page...amp;ProdID=2014 However, the interesting thing is that I obviously need to know which of the 5 pins from the xlr that connects to the poles on the battery (+/-).

Premium Member John Sprung Posted January 26, 2009 Premium Member Share Posted January 26, 2009 I'm familiar with 4 pin XLR, on which #1 is negative and #4 is positive, usually used for 12 volt systems. If you have a cable with the 2 pin Arri female connector going to the motor and a 5 pin for the battery, you could just check continuity with an ohmmeter. Or you could open up the XLR and see if you have red and black wires. -- J.S. Link to comment Share on other sites More sharing options...
Premium Member Tim Carroll Posted January 27, 2009 Premium Member Share Posted January 27, 2009 Those old 5-pin XLR plug ends were on old Arriflex power cables. I'm not sure ARRI actually put them one there, I think they were aftermarket. I see them on cameras once in a while. I usually recommend to my clients that they let me cut them off and wire on a 4-Pin XLR as the old 5-Pin XLR battery packs are no longer available. Best, -Tim Link to comment Share on other sites More sharing options...
Ole Sundsby Posted February 2, 2009 Author Share Posted February 2, 2009 Thanks for your answers! :) Both my Arri 2c and 2b actually has this same 2 pin to 5 pin XLR power cable (to connect with female 5pin xlr battery). I guess these were more popular in Europe, potentially, as both my cameras have been in German hands... After a brief research online: http://en.wikipedia.org/wiki/Digital_Multiplex http://pinouts.ru/Home/dmx-512_pinout.shtml I believe I've found the diagram I was looking for...However, one can never be too sure, as this is obviously not the common Arri 2c cable... Not sure if my battery source provide these female sockets though... Link to comment Share on other sites More sharing options...
Premium Member John Sprung Posted February 2, 2009 Premium Member Share Posted February 2, 2009 These DMX pinouts are very unlikely to be what you need. Since you have the cables in hand, just ring them out with an ohm meter. -- J.S. Link to comment Share on other sites More sharing options...
Premium Member Oliver Christoph Kochs Posted February 24, 2009 Premium Member Share Posted February 24, 2009 IMHO 5 pin was used for 8 V on the earlier Arri ST models in Germany. I would stick / convert to the 4 pin XLR as most modern battery belts use the polarity John described. 4 pin is standard for 12 Volts and also 14.4 Volts (i think the ENG cameras use 14.4) so you're likely to find these in rental houses.

Ole Sundsby Posted May 3, 2009 Author Share Posted May 3, 2009 All, Finally found a very useful document: http://books.google.com.au/books?id=r4LgHi...snum=3#PPA60,M1 Page 60 says it all. Thanks to all for valid input! Ole Link to comment Share on other sites More sharing options...
