i want to download gc2 firmware

[thedancerjin]

my gc2 firmware is 3.8.0.0

so i want to change it to 3.5.1.0

but i cant go this page

http://golfsimulatorforum.com/groups...ftware-updates

i asked to upgrade my account for going to download page. but still i cant go..

i bought protee and tgc so i think i can access to go there

please upgrade my account.

I have been running firmware 3.7.0.0 and have had no issues with tgc and dont see a reason to downgrade to 3.5.1.0. I have not seen firmware 3.8.0.0 - do you have a brand new gc2?

Have you tried tgc with 3.8.0.0? - not sure i would automatically downgrade firmware unless there is reason to.

[thedancerjin]

i know USA forsight sports's new firmware is 3.7.0.0 but i got 3.8.0.0 from korea A/S ceter. they said it is more update verson than USA homepage firmware.

but i have side spin and putting issus with 3.8.0.0 and here recommand 3.5.1.0 firmware. so i want to test with 3.5.1.0.

so i need it but i cant access download page.

We checked the group and the links to the old firmware (3.5.1.0) do not exist anymore. Other links mentioned in this thread are also not working anymore.
You have been added to this group, so you check yourself.

but when i go to download page.. i see this..

Sorry, you are not authorized to view this page.
Please try logging in or logging in as different user Login or send a message to the admin

so how i can check myself?

[Js1010]

If you want to PM me your email , i will send you 3.5.1.0.

I believe i still have it.

Also, i would make sure the gc2 is aligned correctly as others have said but also on a level platform. I had issues with mine giving a bias to one side a while back but it turned out my unit wasnt level. I made a little platform with 4 screws that i could level.

[thedancerjin]

my email is treasurestore@hanmail.net

thanks very much

I may have it if you don't Js. I'd check the alignment.

There should be no need to level the GC2. It has a built in multi axis accelerometer chip which functions as a level indicator and a software program called the Foresight Tilt Calibration Tool to initially align the accelerometer. If you can't get yours to work without leveling the unit is not functioning properly.

My hunt, please send him 3.5.1.0 as I do not have it.


Ronsc1985, that is interesting, I thought it needed to be level. I have the foresight tilt calibration tool and before it runs it tells you it needs to be level. So you are saying it needs to be level just to run the calibration tool but then can self level?

Yes then it stores what the readings are for the accelerometer when level thus zeroing out the manufacturing tolerances and if you run it every now and then any drift over time. This is a common practice with accelerometer calibration.

If you had to have the unit level all the time it would be pretty much unusable outdoors on a range where at a minimum they have by design some side to side and fore and aft slope to facilitate drainage.

Make sense...thanks

Anyone got firmware version 3.5.1.0 ? I want my flash counter back. Anyone help, please! !

[Ronsc1985]

Latest firmware version is 3.10. I have no idea what is different from 3.07 since I haven't run it yet.

If you want to know more about accelerometers and how accurate they are please read this from one of the manufacturers.

http://www.analog.com/library/analogdialogue/archives/43-05/accelerometer.html

The section that is interesting is "Automatic Leveling"

If you don't feel like reading it here is a short summary of the GC2 relevant stuff.

To maximize accuracy and get the most out of your unit. You should place it on a leveled surface while at the temperature you normally have in your sim environment and calibrate it with the mentioned tool.
Then you should place it on a leveled surface while using it.

While the purpose of the accelerometer is to compensate for inclination errors while in the field, it does have a built in tolerance and will add to the total error.
Not a big deal while on the range because it is convenient to not have to bother with leveling. But you have to keep in mind that the specified accuracy of the GC2 assumes a perfectly leveled unit. Since the accelerometer has an error of it's own it will add to the error the camera sensors produce. So while stationary in your sim room you might as well invest some time to get as much out of it as possible. E.g. no point in having +/- 0.1 deg accuracy on the vertical launch angle when the accelerometer will add an error that is much greater than that.

I don't know where you get your numbers but modern inexpensive semiconductor accelerometers have resolutions in the .0025 degree region. Once you get rid of the device offsets by precisely leveling in all three axis and running the tilt calibration tool, subsequent readings when the unit is not perfectly level are compensated for by applying the measured offsets. For the temperature range you are hitting golf balls in the temperature differential error is negligible. Remember these are semiconductor units which have built in temp compensation as a matter of basic design.

Static measurements are actually quite easy. Things get more difficult when you are actually accelerating instead of in essence trying to read the force of gravity which is what these units are doing when sitting still.

I think I was pretty clear on where I got my numbers by linking to the document. That is an application note from a person that works for a company that makes accelerometers. So he is not assuming or guessing. He knows.
The key point to understand about all of this is that the accelerometer resolution and relative accuracy is not the problem. Both are way much better than this application needs.
I have no idea of the GC2 uses a temperature compensated accelerometer. If you know that for a fact then that would be interesting info.
I have never seen an accelerometer that has built in automatic temperature calibration. The process to calibrate it to work across temperature with high accuracy is way much more complicated than placing it on a leveled surface and storing the offset.
