CF-29 and original GPS Problems

Hi @ll
i am just new in this forum. I bought yesterday
a tb cf-29 with built in GPS. I installed the Panasonic GPS Filter driver and
also the reg entries but i don't get a Sat fix.
I use visualGPS. There are only One or two sometimes Three sats
but they also gone After seconds with no fix at all.

Any ideas?

os is winxp

 

Pull the sled out, and flip it over, if you have some copper tape/conductive cloth tape, take the cloth tape off, and cut the copper sheet in thirds and remove the center portion of it. I have done this and it improves signal issues that I have had.

 

You can also check the antenna connection. Make sure everything is secure. You also need to be in an open location so the satellites can lock for the first time you try it out. VirtualGPS is a great program but you may try WinFast Navigator. It is a little more user friendly and is a little more graphic with the satellites shown and their respective signal strengths.

 

As I said before. The oem gps on cf-29 has no backup battery and every time you pull out the main battery or any power, the gps will go back again to a factory default setting.

@ll

frist, thank you very much for your answers. i am just a new owner of a toughbook and from germany. i have some problems with TBtech29 answer "Pull the sled out, and flip it over". are there any pictures because i don't want to destroy something. i have a cf-29 MK4 just for information

thx

 

@psycho:
Das SLED ist das schmale Teil ueber der Akkuklappe, indem Dein GPS oder auch Dein WWAN-Modem drin ist. Wenn Du von der Seite drauf schaust, siehst Du es mit 2 Schrauben gesichert. Diese oeffnen und das Teil rausziehen. Alles klar? Den Rest vom Text brauch ich wohl nicht uebersetzen...

Denis.

 

Yeah, what he said.

 

dankeschön,

yes did it as you said and now have 3 sometimes four sats and also a fix.

@onirakkiss,

please send me your addy to psychoo2katgmx.de. have some more questions regarding cf-29.
maybe you can help me.

 

ACHTUNG! ALLES TURISTEN UND NONTEKNISCHEN LOOKENPEEPERS!

DAS TOUGHBOOKMASCHINE IST NICHT FÜR DER GEFINGERPOKEN UND MITTENGRABEN! ODERWISE IST EASY TO SCHNAPPEN DER SPRINGENWERK, BLOWENFUSEN UND POPPENCORKEN MIT SPITZENSPARKSEN.

DAS TOUGHBOOKMASCHINE IST NICHT FÜR GEWERKEN BEI DUMMKOPFEN. DER RUBBERNECKEN SIGHTSEEREN KEEPEN DAS COTTONPICKEN HÄNDER IN DAS POCKETS MUSS; ZO RELAXEN UND WATSCHEN DER BLINKENLICHTEN.

No need to shout dude!

 

Not shouting; this came from a poster from like... the '50s. It was all in caps, as was the ascii text version that I've had since my C64...

mnem
shh.

 

There is no way to understand this text. Is my english also so not understandable?

 

SEMI-OFFICIAL INTERPRETATION
Attention tourists and non technical lookers.
The toughbook is not for finger poking and grabbing with the mitts (hands)
Otherwise it is easy to snap spring works(like a clock spring), blow fuses and pop the cork with sparks and fire.
The toughbook is not for dumb workers, rubber-neckers (sightseers) so keep your cotton-picking hands in your pockets. Just relax and watch the blinking lights.
(cotton picking could be a term to describe a low-paid, field worker. Or it is sometimes used in place of an expletive starting with the letter f.)
And you both write just fine. Mnmeth is the one that is hard to understand which is why I like his commentaries.
Excuse me for interfering but I needed a break.

 

onirakkiss, Gork -

This thing dates back to like forever ago; before the dawn of computers, almost to Babbage's time. I understand that it derived from a parody "NOTICE" often posted in WWII-era machine shops:

http://www.catb.org/~esr/jargon/html/B/blinkenlights.html

and then eventually found its way to the labs at IBM in the '50s. From there it made its way into pretty much EVERY computer lab in the English-speaking world; I've personally seen it on the wall of at least a dozen shops I worked in as a youth.

http://en.wikipedia.org/wiki/Blinkenlights

The term Blinkenlights has become synonymous with ancient computing devices; even becoming the name of a society for the preservation of antique computing devices:

http://en.wikipedia.org/wiki/Blinkenlights_Archaeological_Institute

http://www.blinkenlights.com/

I thought it was a funny jibe at my English-speaking friends on the forum but I ALSO expected the old-timers here to recognize it; it WAS once pretty much EVERYWHERE.

Translation:

ATTENTION! All you tourists and non-technician looky-see type people!

The Toughbook computer machine is not for finger poking or grabbing with your hands! Otherwise, it is easy to break the springwork, blowing fuses and popping corks with spitting sparks.

The Toughbook computer machine is not for operation by stupid heads. The rubbernecking sightseers MUST keep their cotton-picking hands in their pockets, so RELAX and watch the blinking lights!

I feel SO OLD right now.

 

Thank u Gork! and Mnementh for this small travel into the history of an other language

 

Mnem.... He's just the

 

I liked it I liked it and not only that I started with a C64 too.

Humbly crawls back under the hay.

 

I keep trying to come up with some pithy quip here; I got nuthin'.

LOL... YOUNGSTER... I didn't START on a C64... I STARTED on a DEC running CP/M, then moved on to a Sinclair Z80 I BUILT from the kit. After THAT, I built a couple other Zilog-based machines, moved to MS-DOS, THEN I had the Vic20/C64/C128.

mnem
Not feeling any younger ovah heah...

 

Wow... I started out with the computers on board the Enterprise... Then had to downgrade when I realized they weren't real....

I started (sort of) on the old TRS-80... Then the 8088 then the 386 then 486....

It's hard to believe that my 64GB USB key has over 150X the storage space of my first hard drive...... But then I could always relax and play Pong.

 

ZOMG!

I TOADALLY forgot about the TRaSh-80s! I had a Model III with dual floopy drives and the Z3TA 128K upgrade. I was GOING to upgrade to Xenix on the 10MB external Winchester drive, but I got my DEC before that happened...

mnem
Ahhh, memories...

 

There is a lot of water in this thread. An "sorry" goes to the topic-starter

 

This is a bit dated. I found mention of it elsewhere also. I can't visualize what is going on here. Does anyone have a link to an old photo? OEM GPS on sled.
CF-29F (etc.) not original. But I am trying to get a little better reception.

Thank you.

 

Here we go. First photo will be the sled specifically for GPS option only while the second picture is with a WWAN option(evdo) sled but can be accompanied/integrated with OEM Gps.

ohlip

 

Thanks Teo.
My question is the part about copper in TBTech's post.
Should there be copper under the GPS antenna? Or did he mean something else?
Here is what I have.

Thank you.

Jeff

 

I have taken all out that copper sh..it( I mean sheet) and it works perfect.


ohlip

 

Also on the GPS antenna I know they say (Jim Grey,Toughbook) that nothing should touch the antenna. I think I'll pull the copper and clear that tape off the antenna. Thanks again.

 

I had experimented this Oem gps in the fast and on my conclusion is that it only require a cmos battery backup for the module to work it properly coz everytime you pull out the main battery, you will always start on a cold start on which it take a bit of time. But I have a solution, that nobody tried that before by placing a cmos battery backup to pin 10(+side) series with a single diode. I place a diode on this pin coz I haven't yet a complete set of schematic of the sled and to make it safe so that the flow current will be in one direction only.

teo

 

I want to follow up on this later. Where do I find a diode in this scrap heap?lol

Thanks Teo.
