Steve,
I will take a look at this on Monday and pull out my tech manuals. We can get it figured out. Larry Goddard "01" USA See our ::Goddard:: cables at www.cumulus-soaring.com Steve B wrote: Question 1 I connect 3955 to a PC via ActiveSync cradle using my 9pin cable. With my Garmin 195. The Garmin has: Pin 1 - Ground = Black Pin 4 - NMEA out = Blue Pin 5 - NMEA in = Brown Then pin 5,2 and 3 on that connector. 5 is ground. I connect: black-5, blue-3 and brown-2 on the female PDA cable pin 3 receives data (in), pin 2 sends data (out). I made certain that in the NMEA setup dialog the "Use RX_FLAG" checkbox is cleared. I use the RMC code and do all my testing outdoors on real GPS signal, as I understand the GPS may mark "emulator" data invalid. I set data rate to 4800. I have tried to do serial port testing indoors with enable raw data logging in logging options. When enabled, all data coming in on serial port are logged to a rawGPS_LOGdata##!!.txt file But the file shows 0 bytes. Once I get NMEA data into that file, I should expect program to work with above settings on real GPS data. The pins on the ipaq female connector looking at the connector plug I assume are as follows: _______ \ 54321/ \9876/ So I connected: Pin 1 to 5 on female Pin 4 to 2 on female Pin 5 to 3 on female of Ipaq I checked the Garmin and it is set Inpt / output to Data Transfer and Slave mode The Ipaq is set to setup / NMEA to RMC and (check length) is checked and port is Com 1 Question # 2 I also purchased a generic data cable for the Ipac The generic cable has 4 wires as follows: Pins 1 to 22 2 = Red = Power? I am not using this lead 7 = White = Tx or Rx ??? 8 = Yellow = Rx or Tx ??? 22 = Blue = Ground ??? I could not get it to work with this either... do you know where I can find the pinouts for the Ipaq 3900 that would show pins 1 to 22? Any help on how I can I trouble shoot the problem would be greatly appreciated. Thanks in advance Steve Ps… (just shoot me if I cant get this thing to work) |
