usb serial adapter cable with Windows 7

Former Member over 12 years ago

Im new to this forum so excuse me if this is the wrong place to post this question. I have an older etrex H that I trying to connect to Windows 7. I got this usb serial cable and it fits fine but Windows seems to not being able to find the etrex. Nothing happens when I connect it to the USB port. Any ideas what Im doing wrong? :confused:

No, but you might find installing Garmin usb drivers will help http://www8.garmin.com/support/download_details.jsp?id=591

Forget about your eTrex H for the moment.

Does Win7 recognize your USB-serial adapter? Did you load drivers for it? Did a COM (serial) port get assigned to the adapter? Have you tried using a terminal emulation program, such as HyperTerminal to see if the adapter/COM port are working?

Once you've verified that the USB-serial adapter is working then next question is what software are you using to communicate with your eTex H? BaseCamp does NOT support serial units although the obsolete MapSource does.

The eTrex H is a serial interface unit--it doesn't have a USB interface and hence doesn't need the Garmin USB drivers.

The OP is using a 3rd-party USB-serial adapter which will have its own driver.

Gotcha ... back in the dim and distance past IIRC I had to download the USB drivers for my Etrex Legend H, and had forgotten that the basic H still used a serial interface.

I got ya beat with an original blue eTrex Legend. I don't think any/many Garmin units had USB back then. I remember loading 8MB of maps serially at 115,200 baud. Ahh the good ole days :D

Glad we could help, albeit in a roundabout way :)

Hi, I´m having a very similar issue but I can´t make it work.
I´m connecting a "Garmin etrex Legend" (only has serial interface) to a Windows 7 computer using a serial to USB cable.
I already install and updated the cable driver and the Garmin device software, it connects and Windows detect it on COM6 but when I access "Garmin BaseCamp" it say "No device connected to BaseCamp"
