Help With Serial-to-usb Converter

[+markz68]

I just bought a Garmin eTrex Legend and a Prolific Serial-To-USB converter. I need the converter because neither my PC nor my laptop have a serial port. However, I cannot get either EasyGPS or GSAK to upload data to the GPS.

 

I have checked that the two programs are each looking at the right COM port listed in Device Manager (WinXP).

 

Anyone have luck with this? I really don't want to have to input everything manually.

The laundry list of things to check:

 

1) Latest USB drivers

2) Did you re-boot after installing the drivers

3) What port settings are you using (i.e. port, baud rate, parity, flow control)

4) Do the software settings (Windows and GPSr software) match the hardware

5) NMEA off or on

6) Physical connection to computer and GPSr

7) Can you hook up another serial device and the adapter works

1) I believe so

2) Yes

3) Com4, 9600, 8, None, 1, None

4) Yes

5) off (using Garmin format from GPSr)

6) yes

7) nothing else available to try

If you have a palm make sure that you shut off Hotsync, for whatever reason Hotsync takes over the port and won't let anything else use it if Hotsync is running.

Crap, I was hoping you were onto something. Didn't work.

For a simple way to convert try downloading EasyMPS from this site:

Great tutorial but didn't help my case. I get as far as getting a port assigned and set the software (EasyGPS or GSAK) to match. However, there is no response for the GPSr when trying to upload oe download data. Guess I'll have to load it up from my work PC.

Thanks for everyones help with this, but I never got the generic serial-to-usb adaptor from ebay to work.

 

However, my dad has one that I borrowed tonight and it works great! Now I have a known manufacturer and part number that will work, so I can get one of those!

 

Just for future reference to anyone else looking for one...

 

The Dynex DX-UBDB9 serial-to-usb converter definitely works with my Garmin eTrex Legend!

 

My Dad got his a year or so ago at BestBuy for his race scanner. According to the receipt in his manual, it was $35.00.
