    Sorry for the delay in response. Be working on a car, lost a few valves and the houston heat doesn't help much to work outside on the car.

    Firebuster, that cable should be there by now. You practially live in the same town, and scroll back a page or 2 and TB posted a link or a pic of how to set up the RIM board for GPS. By some odd reason your board is fried (unlikely as TB stated) I have 1 more left and I could donate it to a good cause. I did give one to Ohlip :) I haven't had time to mount that antenna yet but I figure I'll go through a couple of lids before I get something I like. Luckily I have lots of spares.

    Thrasher,
    I got the cable yesterday. I guess the mail moves faster heading north?:D Anyway, I haven't had time to try it out yet, but I hope to have it installed soon. And a BIG THANK YOU for the trade and the help!!:notworthy:

    OK, apparently the Jim Grey is out of business? Is there another supplier of the Sarantel Geohelix antennas? I can't seem to find any in the US...Never mind! Just found Toughbook's post. Sorry.

    I know that this thread is somewhat old but I finally had the time to grind on my lid so that I could hook up my Sarantel Geohelix antenna and solder the leads to the antenna from the EM-408 SiRF III. Sitting in my bedroom at my desk I am getting 6 to 7 satellites. I could not have done it without this thread. Thanks to all. Special thanks to Rick for the daughter board and the coaxial cable.

    Been watching these threads for a while now. Have had my TB for better than a year and has remained untouched untill the other night. Bought it mainly to run automtive diagnostic software for my tinkering. Got around to installing the EM408 the other night, still debating on mod the cover for the Sarantel antenna, in the meantime , pulled the cover off the ant. and tucked it into the bumpout, getting 10-12 sats while driving(f250 fr seat), 7-9 setting in the house, seems to work good there, looses a little when hand over during typing( on my new emmissive keyboard, thnx to springfield). Might try the 27 dbA ant in same location, tho right now pretty satisfied with set-up. Has anybody split the antenna lead so that you could run external antenna while docked in vehicle?

    Back from the dead and having issues!


    The Install:
    Recently bought an EM408 for my 1ghz CF-28, already had a RIM so I removed the card that was in it (not GPS) wired the EM408 as pictured in post 601:
    http://mysite.verizon.net/rickkirby/RIM-Board.jpg
    and switched the number 4 pin to on.

    I went ahead and uninstalled all COM ports via device manager, restarted the computer and set the GPS to 'auto' in BIOS while verifying all the other ports were set to auto as well. I boot the computer, install the GPS driver (from modly's site, calls it a gps filter).

    The Issue:
    No data stream
    No connection in Visual GPS
    No connection found in GpsInfo
    No information being broadcast from HyperTerminal in coms 1,3,4 (the only coms available from what I can see)

    Verifications:
    Pin 5 and 1 were switched around on the EM408 from the picture and how I wired it. Given this is a 3.3v constant on anyway I figured power is power and an on switch is an on switch, no harm no foul. I switched them around anyway... I went ahead and tested the EM408 pigtail from the connector to the board and everything ohms out fine. The Ribbon from the RIM to the Motherboard is in good shape and properly connected.


    So is there something I skipped that anybody can see, or am I looking at either a bad RIM or Engine?

    Did GPS info pick up your GPS on any comm port?

    Didn't detect anything on any com

    First tried VisualGPS, when nothing worked I tried to open HyperTerminal in Windows and connect to all three open coms to see if there was anything going to them, nothing was showing. I figure just for the heck of it I'll try GPSInfo which searches for the data stream a GPS feeds out (testing all ports) and that came up with nothing.

    I wasn't sure if I had to manually go into device manager and switch something around or if just double clicking the .exe file in the drivers would work. Plus if there's something else I could be missing, any tips anybody had.

    Strange because the RIM board should be pretty solid, and I JUST bought this EM-408 brand new.

    Edit: Should it be sending information out regardless of if I have a proper antenna hooked up or not?

    So, I started working backwards and physically disconnecting stuff off the RIM, when I got to the antenna everything shot to life and started outputting like normal.

    Odd, so people, if you have your stock antenna converted to go into your GPS engine, you might want to think again about that one :).
