It probably has TTL level inverted data i/o and needs an RS232 level
interface(MAX232, etc) to connect to a PC.

Save yourself lots of grief. Here are the locations of all the documentation
that you will ever need for your Jupiter. I suspect that the Jupiter powers
up in the default binary data mode and the garbage you see really isn't
garbage:

the serial input of my laptop and run HyperTerminal, I can see the data ok.
When I hookup the output of the Jupiter receiver to the same input on my
laptop, It looks like garbage. I tried every baud rate, stop bits, parity,
etc. I don't have an antenna hooked up yet. I do have an antenna but I'm
waiting for an adapter.

make sure that you set the baud to 4800
select NEMA 103
prob want to hook up 3 volt memory battery
need to convert to real RS232 level signals - the gps outs out ttl rather
than +/- 10 volts or what ever RS232 is
you need a converter chip like a Max-232
I am trying to parse the huge amount of data that the gps dumps onto the
chip

Where did you get the antenna adapter!?! I have four of these Jupiter
boards ready to test with, but I haven't ordered antennas yet. Have you
determined the exact connector required?
The spec sheet for a -221 says that it offers a straight OSX ( female? ) on the
board. Can't find many of the small active antennas that offer an osx
connector or adapter. I read somewhere that OSX is also called MCX but that
didn't help things much. Ideally, I'd like a right angle adapter and then be
able to connect the antenna to that. I need to stay with the smaller family of
connectors for a small footprint application; the usual bnc is way too big for
my app. There aren't many 'quick order' sources for a solution or reference.
Care to share your info? (g) In exchange I can offer the name of a vendor that
sells a plug-compatable replacement for this board. The prices are decent
too! This vendor has antennas at quite favorable prices ~$25.00 in low qtys.
I have not determined if this is an active ( probably not ) or passive. Great
price if it is an active antenna.
Thanks,

From my research your going to need to add a MAX232 to the TTL level serial
pins provided by the Jupiter. There are some serial ports that are forgiving
enough to tolerate the 5v swing, but laptops are notorious for not being among
them. Additionally, the 0v low logic level is even more troublesome as the
true RS232 spec calls for a +12v/-12v swing. The MAX232 is an quick and easy
solution and will remove all doubt concerning serial data line flakiness.
Hope this helps,

works fine outside

seems to make no difference as to straight wire or curled up for circular
polarization

When I was reading back researching for the prev post I saw a post from you
( I think? ) saying that they had used an 8" length of wire successfully. I'm
willing to try it as long as it shouldn't harm the unit. My analog ele is weak,
does this provide a sufficient load to avoid any damage to the receiver or is
this even an issue? What about the antenna ground lead in this case, just
hanging open or what? This sounds like a great temp solution until I can line
up a right angle osx/mcx/sma(b?) connector and appropriate mate for an antenna.
I have been delaying my project ( and powering up any of these boards! ) until I
had an antenna to connect up.
All the 'shrink-wrap' antennas have a huge lead on them as well, I'd like
one about 3" long and several others about 10" long only. I think I'm gonna
have to roll my own! ( If I can source the connectors that is...) Thanks for
the tip though and I would welcome any additional insight you may have on the
above issues...

Save yourself lots of grief! Here are the locations of all the documentation
that you will ever need for your Jupiter. I suspect that the Jupiter powers
up in the default binary data mode and the garbage you see really isn't
garbage. You will need to command the Jupiter into the NMEA mode as it's
native mode of communication is Binary. Please take the time to read ALL the
documentation:

rx - it just wont work as well as it could. That however is definitely not
the case for transmitters and transmitting antennas.
Also the gps is in the 1500 MHz range - that is the reason I choose a 4 or 8
inch wire since it is a multiple of the wavelength.
The transmission line losses are huge at that frequency. so make the lead in
wire as short as possible- I had a zero length transmission line when I
soldered my antenna to the center terminal.
an active antenna is a good solution to the problem but I am on a shoestring
budget and I didn't want to spend $30 -100
I know that ground planes are good for vertical polarized antennas, I guess
I am relying on the ground traces on the board for the ground plane - it
works anyway
Also I believe that the gps signal is right hand circularly polarized - I am
not sure that a ground plane helps in that situation.

Actually is was sent to me from someone else. A piece of wire would
probably work on a passive antenna but not an active one, (which needs a dc
voltage to drive the preamp in the antenna).

Thanks for the response. I drove the NEMA Protocol input pin 7 to a low per
the documentation and I still can't interpret the data.

Thanks for the response. So the output of the Jupiter is TTL? Let me know
if you need help deciphering the GPS data. I have the code that deciphers
GPRMC data line. Easily changed for your app.

There is a company in Jupiter/Stuart Florida that sells the adapter but
the adapter I want is for a Motorola active antenna I got free, (pre amp
included). I did a search for OSX on web crawler and yahoo to find a
company. You can also buy connectors and crimpers for them. I don't care
to go that direction. By the way, what is DCS.

Great

Have you found out where you can get the adapter for the Jupiter GPS yet..
I am working with one as well, and have yet to find a source for the antenna..
BTW... have you found any place that carries the adaptor for the pins. I
relly do not want to just solder the wires in place. Any infor you can give
would be of great aid, as I am planing on using this unit in a project for
school.

and I have a few questions.
1. Has any gotten the Jupiter to work in RMC mode yet, and if so how did
you get it in the right mode?
2. Did you find that you where able to directly hook the STAMP to the
Jupiter with the serial port?
3. Where you able to get LABMON working?
Any information or schemactics on how you have gotten the system to work
would be of great aid...
Thnks in Advance..
Joe
what is rmc mode ?
thanks
richard
