[time-nuts] Help with pinout on Trimble NetR5 GPS receiver 26-pin connector

[Stan]

I just happened upon a Trimble NetR5 GPS receiver in working condition at a
irresistible price. Unfortunately, there were no accessories provided with
the receiver.

 

I need to charge the battery, and I was hoping to hook into the 26-pin
connector to do that. I downloaded the user manual for the NetR5, but it did
not show the actual pinouts. Then I downloaded the manual for the NetRS, a
similar receiver that has the same 26-pin connector, and I'm assuming the
same pinout. The NetRS manual does show the pinouts, but for some reason the
list has omitted pins 1-5. Based on the functional descriptions of pins
6-26, I'm pretty sure that it's two of the first five pins that are used for
external power and battery charging.

 

Does anyone know which pins are used for that?

 

Thanks,
Stan
