Any suggestions for USB to Serial converters?


Recommended Posts

Posted

Just wondering if anyone out there could tell me what luck they have had with the different USB-Serial converters. I want to use an eTrex with a Toshiba laptop running WinXP Home, and I have seen a number of threads with varying degrees of luck... suggestions? Thoughts? Thanks!

I have a Xircom that I use for my Palm interface, and have tried it with my eTrex Vista, and while it worked fine, it did not speed up data transfer as I thought it might.

 

Any Comment?

AFAIK the adapter emulates a serial interface and has the same speed limitations with a max. baud rate of 115200.

(thats one of the reasons why the SD Card with Card Reader is a great feature of the Meridians)

Makes sense, the same 0's and 1's end up squeezing thru the same serial port. the adapter just lets you get over a connection problem.

 

So where is the transfer speed limit? In the handheld? Even if they built a jack with a USB on one end an a connection to the handheld at one end it would still crawl?

I'm using a Belkin FSU409, and I can't say I'm totally happy with it. Map uploads won't work at 115K, and at 57K it's as like as not to hang up after a couple of minutes. On top of it, it can no longer be found on the Belkin website, and the existing drivers aren't XP certified.

I am using an HP cable. I also have an HP laptop so the connection should have gone without a hitch. It did not. It seems that when I made the connection it assigned com9 to the connection. Once I changed the assignment (com1 thru 3 were available) everything worked smoothly.

Appreciate all the input. Have to admit in the end, I just took the easy way out and ordered the cable that GPS Central had on their website. They offer an easy return if it doesn't work, so we will start there. Thanks again! icon_cool.gif

I purchased one of those things yesterday because I wanted to upgrade my Vista to the latest software. I tried everything but couldn't get it to talk to my GPS any faster than 9600 baud in either Mapsource or EasyGPS. Many times the driver crapped out and popped up a error message (same popup in EasyGPS and Mapsource so I'm assuming it's the actual driver software) and I had to reboot the GPS to get it to see it again (so I could try the upgrade over and over again).

 

This afternoon I went to Fry's and got a IOGear GUC232A. It doesn't have certified WinXP drivers but it's been working great at 115200. I even tried upgrading the software just for the hell of it. Man what a difference! No errors and it was 2 minutes instead of 22 minutes (no kidding!).

 

Plus this thing is MUCH smaller than the Belkin. I couldn't find any of the other brands - Sakar or Keyspan. I looked in the Mac section, too. No dice.

Looks very much like the Hawking and the IOGear. Almost too much like it!

Lots of high praise for his usb/serial converter.

I read somewhere on the internet that this adaptor only supports 1 or 2 of the methods of communication.

 

The one at gpscentral smells much like this one.
