Geodimeter 400,500,4000,600 and Trimble 5500/5600 toolkit

@bugg you can do that externaly with serial commands. Just do the math, how many points? 1000? 10000? 1000000? how long does it taoe for edm to calculate distance? Multiply it by how many points you want and you are screwed. It will not fit into your workday.

Excellent product, 

First and only working prototype of "geodimeter multi interface".

This device serves multiple purposes:

  1. 400/4000/500 station programmer, also talks to 200 distance meter.
  2. serial port connection to 400/4000/500 stations (mostly for debug, and/or other uses)
  3. radio interface - for 600 station
  4. it provides output for hobby servos for 400/500 station calibration

First 2 points are already verified and working. The radio needs lot of firmware coding. Not done yet - corona lockdown was released and there is little time to work on hobby projects.

Calibration was tested on my own 400 station. I have been able to calibrate VA axis, bud no time to test HA axis. I have mechanical problem on this axis.


 

Hi robots, I am new to the site. Is there a way to upload this firmware to my Geodimeter 540n? If I get a serial cable to USB will it communicate with Windows 10? Thanks for your help and expertise you are a savior! 

I am having problems reading out my 5602 , see pic.

Any suggestions ?

 

 

@hvac you need to do this on station without CU. otherwise you are talking to CU and not station. Second ... what is your firmware in station ? you should see that by sending ? command over terminal

@lazyfern no ... 400/500/4000 stations need special interface to communicate. And your station still has firmware, its only missing calibration and some other variables.

Station is turned on now, shining laser on my wall and making UUUUU sound.

If you don't mind, what exactly is all this for?  What Total Station are you using with laser on wall?  Thanks!

@timd1971 all geodimeter stations (since digital age) have battery inside. This battery makes memory inside of the station not forget stuff. By stuff i mean: Calibration constants for angular sensor, calibration for servo board (if there is one), tracker, various constants used in computations (in gdm210 all math constants).

Since last year or so all geodimeter stations are not supported by Trimble, only way to make "service" on your station is to bring it to shop that already serviced it (they still might have copy of the calibration constants).

Ah yes, those calibration constants - they do not change at all. Its not like they calibrate each sensor separately. They upload the same data into station as factory did, check mechanical alignment, grease, oil and return your station. Yes you get new battery that costs 5USD. But the cost is nowhere near 400-600-1000USD as they ask.

So with these tools, you can make copy of the internal memory of station and CU and you can change battery yourself at home and later reupload content of memory. And if you are careful enough not to drop your station to ground/hard surface chances are that the mechanics is intact. (or if you get sand inside, you are in trouble). You then make the alignment that's in manual, and your station is good to go.

 

Problem is that there is very little number of 400/500/4000 stations still working. So i am working on how to calibrate these at home. It should be same for 600 station, but its still long way to be done. And if someone is going to argue that this calibration is not precise enough as factory calibration - yes you are right, but for playing it is ok 🙂 i am not surveyor.

@robots Thanks for the detailed explanation! I did not get this answer when I asked multiple repair shops, and all of them do not service these older units anymore. The person who sold the geodimeter to me failed to tell me that the internal battery was shot. I was getting error 54 (no internal communication). I was also told that I had a large paperweight and better off making this museum piece! Hoping I can revive this unit with your help, thanks!
