Hi all
I need to put together a second unit to send off to do some static obs in a couple of weeks. From what's left in the kitty I have a topcon sr and a trimble zephyr that pairs up with a trimble 5700 reveiver.
No concerns with the sr but I'm assuming I'll have some issues with observations from the 5700? These will have the date issue? I have had this in storage for a few years, what would be involved in getting observations out of it that I could then process? I know I'll need to convert the data to rinex but the date issue concerns me.
Thanks
John Hamilton wrote a program to fix that. I believe he posted it here.
Try it out. We've had our units for a long time and they work just fine.
No problems with our 5700 re:dates, but an occasional issue with not recognizing the CF card.
Just make sure the firmware is the latest (which itself is rather old). Some even older firmware versions require date fixes to the output.
Hi thanks for info. Been searching online and it looks like I need to use winflash to upgrade firmware. Winflash asks me to type in password for my 5700... I bought it second hand and have no idea, I've emailed trimble but not expecting an answer any time soon. Does anyone know how to find this? Thanks.

Most Trimble passwords are 1111, 0000 or 1234.

You may have already seen this article..

I also have an old 5700 stuck at FW v2.12, I also emailed Trimble for a code to resolve but no reply..
I also contacted the local trimble dealer here and they are happy to renew the FW for $750... no thanks.
Run Winflash, go to Receiver Options, and check your warranty expiration date. If it's anything older than Dec 1 2004 then you're probably out of luck. Also check your version number; 2.32 was the last one but 2.21 and later are probably all OK. Anything prior to that might be sketchy.

If you're using TBC, there will be no issues whatsoever. We use ours from time to time and it sends and receives data from OPUS and processes static vectors just like it did in 2000 when we got it.
For OPUS you definitely want to make sure you have the most recent version of the Convert to RINEX tool off the web site.
I just got a "new" 5700 yesterday. It has older firmware, I updated it to the latest one I could put on it (warranty expiration 08/2004), which is 2.26. That is apparently not recent enough to fix the week number problem.
The bottom one is today's file. Apparently it has not been used since 2009.
I also received a "new" Trimmark III. It has older firmware (1.11). I tried to upgrade it to the newest using winflash. Three of the four options in winflash work EXCEPT for the upgrade firmware option, winflash freezes on that. There are intermediate versions, would loading each of those first help? It is configured for 25 kHz spacing, but my dealer says they can change that to 12.5 kHz.
I've all but had it with trimble. Topcon and Leica seem to just work no matter how old they are. Trimble always mysteriously seem to pack it in about the time they are about to bring out new gear such as TBC.

I agree that latter-day Trimble gear is more challenging to use into senescence, but I still have about nine 4000-series receivers (mostly SSi and a few SSe) that continue to provide rock-solid solutions. Roughly 20 years old, some of their stablemates have failed beyond my ability to repair them, but for the investment they've all delivered remarkable service.
Senescence - what a great term! Kinda what I am starting to feel like ...

Well maybe, but that might be a gamble, that radio dates from about 2004 (ish) and even though by FCC rule everything approved from about 1996/97 forward was supposed to be narrow band capable, the vendors were playing games and in reality I think they knew what they were doing. Notice in table below (copied from Pacific Crest web site) that Trimmark III shows either 25 khz OR 12.5 khz, BUT not both. I bet it was an option to get 12.5 khz and not a standard issue. You may have to run in 12.5 khz equivalent efficiency mode which will probably provide poor performance at best.
- Data operations on channels greater than 12.5 kHz must employ data rates greater than 4.8 kbps per 6.25 kHz channel, such as 19.2 kbps per 25 kHz channel.
19,200 is likely to cause data collisions at 1hz update and generally poor range and performance.

Shelby: I was not aware that the Trimmark II was ever available as a 12.5. I have an OLD Trimmark II that I don't use anymore. I think you may be right, the manual for the Trimmark III says either/or, but does not say that it is changeable. But my rep at the dealer says it can be done, I guess I will find out.
Jim, you are absolutely correct. The same goes for my old trimble gear. My 4700 units are compact enough for me and are bomb proof. My mini zephyr antennas the same. Any work I do with them is static/fast static so gps only is not a problem. Paid good money in the day for them and TGO. TBC comes along and magically TGO can no longer play with them except for work around so done by fantastic members of this forum... if trimble could produce TBC ofcourse they could supply a fix for TGO. Would that have made good business sense? They wanted everyone to rush out and buy TBC and more recently, newer gear. How many did? The fact that fixes and workarounds have been created by third parties makes me think the answer is less than trimble wanted. I don't care that I bought the gear years ago. I bought it because it was sold to me as being rock solid and investment worthy. The only reason it no longer works is because trimble decided that would be the case. My main gear is now leica and topcon.

Yes, the Trimbark III can be changed but requires the dealer to reprogram. Had it done to mine. Set me back $125. Good solid radio.
If the log file is for a static points, to be converted to RINEX, I have tried out the Teqc program from Unavco to force the correct week to be applied in the RINEX conversion and it works fine.
So unless Trimble responds with a complimentary code to allow me to bump from 2.26 to 2.30, that's what I will be doing.
