Hi all,


About to buy myself a battery/charger for my Arriflex 2c here:

http://www.batterysp...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

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

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.

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

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://pinouts.ru/Ho...12_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...

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.

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.
For the complete cable:

For the 4 pin Neutrik plug:

All,

Finally found a very useful document:

Page 60 says it all.

Thanks to all for valid input!
