Settings for Fugawi 4 and GlobalSat BU-353 GPS??

Hi Everyone,

I recently had to buy a PC (not thrilled) for software development work. Because of this, I can no longer use my beloved MacENC navigation software. The wife got the Mac.

Now, I am looking to different software package to use on a PC and have settled on Fugawi. I have a USGlobalSat BU-353 USB GPS that supports NEMA Version 2.0. According to the Fugawi website, any NEMA GPS (V2.0 or V3.0) will work:

Fugawi GPS Compatibility Table

This GPS works wonderfully on my Mac with WAAS and everything. Now that I have moved it to the PC to try and use it with Fugawi V4, I am not getting any NEMA traffic on the GPS Log (in Fugawi).

My settings are...

For the COM 4 port: 9600bps, 8 data bits, 1 Stop bit, Flow control = "none"

According to the operating system, the device is "working properly" using the Prolific USB-to-Serial driver V2.0.0.26

Inside Fugawi, my settings are: Port=COM4, Speed=9600, Parity=NONE, Data Bits=8, Stop Bits=1, Flow Control=NONE. These are set for a NEMA type GPS. All other settings are default.

No parity changes seem to make a difference. Does anyone know what I could do to get Fugawi to talk to my USGlobalSat BU-353 USB GPS??

Thanks

GPS issue fixed!

Would you believe I had to use a very complicated, highly technical approach?

I worked through all kinds of diagnostics at the COM port and GPS NEMA level and it all came up negative. So... I took the GPS by the cord, swung it around in a circle and smacked it into the salon table.

THIS was the solution!!

Now it works perfectly. ???

Sean,
The BU 535 GPS engine is very sensitive and often requires re-calibration. You obviously swung it clockwise as this is the recommended method.

Actually, 9600 is maybe OK but it only needs 4800. The NMEA standard is 4800. If you can set oth ends to match then I guess you have it OK. The trick is to turn on the GPS AFTER windows is all booted. If you don't, then when Windows boots it grabs the GPS as a mouse and the data as mouse input. It's a great show to watch.

Ha ha ha.... thanks Paul. I did find that 4800 was the correct NMEA speed and reset those very soon after the initial post. The fix, literally, was to smack the GPS into the salon table. I swung it around on its cord and gave it a good whack in disgust. It was still plugged into the USB port and the minute it hit, NMEA data started flowing on the NMEA monitoring screen. No kidding.

I almost got up and did an "Eeeeeeeehhhhh!", Fonzy style.
