Testing

I don't understand what that video was meant to demonstrate. Unless the internal circuitry was poorly designed or assembled, there's no reason for the bluetooth connection to fail just because the receiver's moving around.

This receiver works just fine :good:

Now try the 'Big Help' unicycle test!

There was a complaint that this particular receiver would loose it's Bluetooth connection when on an ATV barreling down the road. Could be the data collector too, but the claim was only this head. We sent out a loaner and got it back to test. Of course, they always work when we get them.

I pounded it on the pavement for 1/2 an hour before we made the movie for customer.
I posted on YT for customer to watch and Mr. Ott found it through a YT subscription.

You are absolutely correct, the Bluetooth should work without fail when you bounce them around.

Mark, that was a hoot.......

That would practically be what the tools would be put thru while attached to an ATV running around some of the rough terrain of the hog revenged pastures in NE Texas.

Note to self...don't bring your equipment to this business to be repaired.

I can just picture it....
Dear Mark, we are enclosing one Trimble S9 Total Station (serial #8081686189dh1r8081) for diagnose and repair.
Our field techs are stating that after riding in the back of the truck for extended period of time, the total station intermittently fails to power up.
We suspect it may be due to bumping or jarring during transport.

Flash forward a couple days..................receive E-mail from Mark with link to You-Tube video.......click on link......Mark is demonstrating his diagnosis/testing method............->"This unit works just fine!"

WTH?!!:-D

Not to say you are not correct, but wondering if you have tried to mimic the owners actions. Might load up and drive around with the unit sticking out. Question? is it straight up and down or leaning backwards? Is there something else interfering with bluetooth (i.e. a cellphone or other device trying to gain BT). I know I have a rover radio that will quit recieving the signal but still be on. I can cycle it on and off and it picks it back up. I try to replicate at the office like you do and it won't fail, but once I get out and start moving it happens. Still haven't figured that one out.

My thoughts as well. Could possibly be RFI from the ATV ignition?

Our TV used to have horrible reception when the neighbor rode his dirt bike (1/4 mile away).

I am all over the spark noise idea, but it supposedly is only this receiver. Not the other one or the loaner.

We may never know as it probably won't have the issue when it returns. If it does I will just replace the unit.

I should disclose that I took the receiver down to the bolts and rebuilt it before testing. But I could not get it to fail before rebuild either.

This rod test is fairly common for me, I used to sell another device with an internal radio connection that would not survive that test if the ribbon cable had any issues.

I would not test any optical instrument this way, but I sell RTK to seismic crews and this is SOP for them. Plus throwing receivers in the back of a truck with shovels and 1,000 jugs. So that equipment really takes a beating.

Time will tell on this unit...
