We have 10 Trimble R5 receivers, 9 of which are in the field and seem to have intermittent operating behaviors. They go down, then reset and come up, then go back down. There does not seem to be any rhyme or reason to the units' behavior. Is it just our units or have other users experienced the same screwy behavior?
Kinda sounds like a cable problem, from days gone by. Are these things bluetooth?
No, these are ALL permanent CORS units that use secured cables from their respective rooftops. We have over 60 installations state-wide, but only the R5 units are exhibiting this screwy behavior. None of the various other models of Trimble receivers, newer or older are having this problem. It appears to be associated only with R5 receivers.
Cliff,
Are these units NET R5s or the integrated R5 units w/ the radios and Bluetooth?
The Plate Boundary Observatory (UNAVCO) uses NET R5s I beleive, so they might be someone to talk to.

Yep, these are NET R5 units.
You have ten of these units.....aren't you getting any support from someone?
Ah, to make a long story short; no.
Cable problem? Connector Problem?
Perhaps heat conditions are causing expansion inside the unit, creating a break in current flow.
It could be one component in that model that is faulty that needs to be replaced.....but one would think other users have had the problem and Trimble would be aware.
Exactly. That's why I posted the question. One would think ...
Erratic power?
We have LOTS of these deployed as CORS stations and usually see no problems with them.
Have you hard resetted them?
Pull the power?
if you would like to email me at tbryant@seilerinst.com, I could give you a phone number to call....
Yep. Resets, powered down, etc. We keep connections with our modems when not hardwired to the internet; the Net R5s still act screwy when the rest of our gear is not affected. We even have UPS units hooked into them.
Check to see if the Power Save Mode has been set to on, I remember a problem with a unit cycling when power save mode was turned on. I am pretty sure it is on the data logging status page.
No help with your issue, but I feel for you when it comes to Trimble Support. It is almost non-existent. They rely on dealers, then make you pay if you want to speak directly to Trimble.
I can tell you how it will go......your dealer will be unable to resolve your issue (at least not at the speed you want). They might even tell you that your equipment is old and needs upgraded. You call back every day and they say they have not heard back from Trimble Support.
You refuse to spend more money after spending thousands and thousands, you get tired of waiting and find a phone number to Trimble's direct support team......they tell you they are not any support group, they are the ELITE support team, they do not have time to deal with your issue without a credit card ($30 per issue, $500 per year)....you are supposed to go through your dealer.....they will accuse your dealer of not providing you support. Eventually after several weeks of frustrating e-mails back and forth, the issue will be resolved by Trimble telling you you need to buy new firmware for all of your units. You refuse and they offer a one time free upgrade to resolve your problem......until next time.
I do know Trimble units have been known forever to have overheating problems that cause intermittent glitches that are a bear to diagnose. If possible, you might try to use an external fan if power supply is not an issue. JRL
Thanks; I have forwarded your comments & offer to our Network Manager.
