Need some insight from this fine bunch.
I have an old Trimble RMT 604 that I have and wanted to power it up from an external battery. Does anyone have the pinouts at the connector (hirose 4 pin)? I know how to tear it down but not sure what pin does what.
Found it runs on 12v DC with max 150mA. To power it I was thinking of using a Boost - Buck converter/regulator. I know that Mr. Frame and or Mr. Larson has tinkered around with these things and if you guys got any data it would sure help.
Thanks.

I did see that post and I believe that was for the 5600 connection. Will it work for the RMT though?
Just looked at my Geodimeter 610 with its RMT 602 and both have the same pin assignment as shown in the thread above.
Yes the 604 has the same pin assignments. It is also setup so you can screw on the large glass array from the S6 and have the same distance LED's to glass. The LED's are very sensitive to voltage, so, I would not buy a non variable voltage regulator and depending on your power source you may start as step down and finish as step up. Regulator efficiency is better on the one way regulators, so, depending on your source you may want to add a cell to force it into a continual step down situation. Inefficiency is turned into heat, which, at these amperages isn't a big deal, unless you wrap it tight. You can get different voltage cells, but, in general a LiPo or Li-ion cell is 4.2 at full charge, so, three together makes it step down then step up as it depleats
You do not need the four pin assignments for power but it is shown on the start of this thread https://surveyorconnect.com/threads/parani-yet-another-thread.316742/
Here is where I got it through my thick head that I needed precise voltage https://surveyorconnect.com/threads/got-my-printed-battery-case.241500/#post-269677
I am using these regulators ( http://www.dpcav.com/xcart/Adjustable-Voltage-Regulator-1-35V-SEPIC-Type.html ) for the 360å¡ battery's that sit up on the poles with the 360å¡'s. I am using them because they turned out to be too weak for the instrument batteries and by then I had a stack, but, with a volt meter you can put them right at 12.00 volts. Also remember the 12.00 volts is under load. The LED's also cause surges, so, make sure your regulator is way over what you need.

I also remember that the draw was 175mA, but, I can't find my notes.

Thanks guys for all of the feed-back. Got called away for a few days.
Norm: Thanks for the recommendations for powering it up. I was looking at testing on some spare LED's I have lying around (10 in parallel/serial hmmm). Getting a pure stabilized power source isn't that difficult, just takes some testing. Maybe going to add some capacitors/resistors to the output circuit to insure the amps are fully controlled.
The link for the regulator you have looks nearly identical to one I found on Amazon made by DROK LM2577 DC Boost Power Converter . Which had a lot of positive reviews. Testing it now. Took a 9 volt and ramped it up to 12 volt. Ran it that way for about 20 minutes and it didn't hardly warm up. Output was stable and clean. Pretty efficient. These little converters are amazing.
I saw your case builds on Shapeways. Very impressive. Once I get the RMT up and running I will be back to check those out. Parani is not the only class one bluetooth anymore. But probably the best one. They are made by SENA I believe. They make a motorcycle bluetooth - which I use in my helmet.
