Post by: old and in the way on September 21, 2013, 12:46:03 PM
Looking at the solder end of a 4 pin hirose . Is this the correct pin configuration . i want to make a power cord for my 744./Users/jimmalogorski/Desktop/DCout.jpg

Pin1 = -
Pin4 = +

If you look at page 15 of the data sheet it shows it but you are correct.

Thanks alot . The pin diagram was a little vague on which way you were viewing . i have it now again thanks .

Reviving thread for clarification.  Does the following correspond to the pin assignments for the 7xx when viewing the recorder's receptacle?

Scratch that.  Yes, that is.

What cable gauge do you use with these Hirose connectors ? I see the manufacturer says 26AWG but that seems very thin (and expensive).

Actually, I'm just pilfering an old power supply cable to use it with an "N" connector.  The only soldering will be on the other end of the cable.  Soldering a Hirose connector itself is more than I'd want to try; they are really small.

I just bought a XL-H Sound Devis 4 pin hirose connector,  HR-10P-4P.  i can't  figure out how get the pins out of the casing in order to solder a cable onto it. Any ideas?

The piece with the pins/solder cups unscrews from the external housing. Perhaps the easiest way to unscrew it is to plug it in to the receptacle and use the "flats" at the rear of the housing to turn the housing off the piece with the pins/cups. That would be much easier than using a fingernail to attempt to hold the innner piece while unscrewing the outer. Note there are about 10 threads so you will have to unscrew for quite a bit more than you initially think.

If you need pics of the disassembled pieces I can post one later.

Thanks for the reminder that I need to break out the iron and solder a few Hirose connectors myself.

Thank you, never would have figured that out.

Great, now that I know what pins are what, what are some good alternatives to use for external power for a 744T?  In other words, what do I do with the other end of the cable and what are small, lightweight, power supplies that will last a few hours or longer for a day long festival?

I always used a RAVPower 23000 with my 744. It has variable DC output through the 2.5mm plug.

Thank you, these are the options I'm hoping for.  How long can you power a 744T without concern? Did you just make a cable to go from the RAVPower 23000 to the 744T and no longer need other batteries?

Ted made me the cable. I always ran a Sony L series 770 type battery as a backup too. I don't remember specific run times but did a few festivals without issues.

Being able to record a festival without any issues speaks volumes.  Thank you.

Looking for feedback:

I'm interested in using an external battery with a custom cable that would go to the [hirose] power connector on the SD 744T.  I found a Poweradd Pilot Pro 2 23000mAh power bank that seems good and was wondering if anyone has experience with this scenario.

I would be using the 12V option on the power bank.  It is my understanding that the 744T draws less than 2 amps and with this size power bank, should last significantly longer than a 8 - 9 hour day of recording (or 3 shows?).  I know people have done similar configurations with external batteries, whether with a custom sled to attach the power bank to the battery terminals (using a 9V option) or using the hirose connector to go to the power terminal (12V option).

My question is, who has done this using the hirose connector, what have you used, and how long recording time do you get?
