Hey gang, new user. I am not a surveyor, just a simple carpenter/construction site manager! Sorry for the long post!
one of the surveyors we used to utilize has recently retired and cleaning out the storage at his old office came across a Nikon DTM-20 in its case with a prism and rod and a tripod. Of course the battery on it is toast and the external power pack, spare batteries and charger have all disappeared. He gave it to me as I had expressed interest in learning to use a station in the past.
As the batteries are no longer available and I didn’t want to send it out to be recalled, I removed the old ones and was able to pick up a couple of battery packs from Amazon that are the correct voltage, and a higher amp/hour rating so I get longer run times. This worked out well and the battery packs just clip to the old handle battery empty housing.
it also didnt com with a data logger or a cable.
My question here is the data cable. It has a hirose 5 pin connector and I can’t find anything that will match up to it, nor can I find the pin out diagrams to figure out which pins are used. I know 2 are for send and receive, and 2 are for power and ground and the 5th most likely unused. Am I missing something as there is no way this would match to a 6 pin connector. Is there anywhere someone knows to find said data cable of would it be easier to open it up and replace the connector with a t pin hirose connector and get the correct data cable?
second question , I’m not interested in purchasing a dedicated data logger, I would like to add a 6 pin to Bluetooth module as well, they are on Amazon and have their own battery and power supply, does anyone know if this would work if I changed out the output on the machine to a 6 pin?

Paste this link into Google. It might be your DTM cable.
@landbutcher464mhz that is the 6 pin hirose connector not the 5 pin that this machine has . I’m thinking my only option may be to replace the port with a 6 pin of if I can find the wiring specifications somewhere . I am unable to attach images yet
I have a Nikon DTM-332, which uses the 6-pin connector. The pins are
1 Receive Data
2 Transmit Data
3 Power 7.2 to 11 volts
4 none
5 Ground
6 None
So there is a good chance your 5 pins correspond to the first 5 here. No guarantee, but maybe you can find a way to confirm it.
I also don't use it professionally. This unit has a lot of software in it. If you are doing exactly what the software was intended for, it is great and does all the computations you would want. But if you do anything out of sequence you may be better off with a field book.
@bill93 I think you are correct, I think if I can figure out which on of the 5 is unused, hopefully it’s the random on that won’t fit the 6 pin layout and I remove it so the 6 pin will fit?? Then I just need to figure a data collector of some sort. I just want to play on the farm, layout fences and put buildings and stuff. Maybe map out some 30m setbacks from the watercourses. I’m thinking if I can get the 6 pin to work and add Bluetooth then use a tablet I already have. Trying not to put a bunch of $$ into it , learn how to use it and then maybe upgrade to something better one day and pass this along to someone in the same situation! Does anyone have an image showing PIN numbers???
This might be a simplistic question, is there a convertor available to convert hirose 5-pin to hi-rose 6-pin?
I've seen stranger things.... Mouser.com and other electronics houses might have something in this arena.
Western States Cabling has helped me out in the past. The link is for their website. Good luck.

@not-my-real-name thanks for the link I will check them out
@bill93 so would the pin numbering match at the other end on the RS-232 I wonder? I think I could build a cable. I have horse 2 pin connectors and all I need is Rx/Tx so if I can trace pin 1 and pin 2 on the other connector I can build the cable? My $30 for 2 -8.4v batteries with 3x as much run time as the originals has worked fine and the machine works great, now all I need to do is get it to communicate with a tablet !
Those pin numbers do not match the common DB-9 pin numbering for RS-232.
@bill93 I don’t know why I thought I wanted RS 233, it is DB9 and I’m guessing they will match at each end?
So I have removed the old connector, no luck identifying it. Attached are only 3 wires, Rx/Tx and power that would have come from the external battery. I have ordered the correct Nikon data cable and the matching female connector to attach to the machine. Now before soldering in -lace, I need to figure out which wire is which. One each of red, orange and brown. I’m guessing the red was external power that was grounded by the original screw connector. I believe I can use the pin numbering mentioned above for the new connector and I should be in business!
