GPS Receiver BU-353
I am having a problem with OPNCPN reading my GPS. I had this working in the past and received good positions in Delaware Bay. We have shifted to Lake Michigan (via car) and my GPS no longer shows that the GPS/Nmea Data Stream Window is getting info. The Data Stream window in blank. I have moved the boat on OpenCPN to its location @ Douglas, MI and centered the map over it: then hit AUTO FOLLOW but get no GPS
I have gone to the GPS set up and redone steps 4-14 but still get no input in the data stream window. The GPS unit indicates that it is working fine by flashing a red LED.
How do I get it to input data into OpenCPN?
I'm not very techy when it comes to solving computer problems so please be very specific with guidelines.
Thanks for your expertise,
Don

Re: GPS Receiver BU-353
It sounds as if your BU-353 has slipped into Sirf mode. Search for and download SIRFdemo.exe. Use this program to reset the gps to NMEA mode.

Re: GPS Receiver BU-353
Thomas,
The GPS is working fine in Coastal Explorer. Does that still mean that it has slipped into SIRF mode for OpenCPN?
Thanks,
Don

Re: GPS Receiver BU-353
Corlfoot,
Can you find what "Port" Coastal Explorer sees the gps?And then set OpenCPN to the same in the GPS settings?You have already read the OpenCPN helpfile... and I don't have CE but most Nav apps are similar.
(FYI per above:You can only run the gps to one app at a time UNLESS you want to try "XPort" or another "Port emulator"...XPort can search for the gps for you and save some computer tunneling to identify the port.)

Re: GPS Receiver BU-353
Happy Seagull,
Both Coastal Explorer and OpenCPN are using COM5 for reading the GPS. I just opened up Coastal Explorer and it wasn't reading the GPS. Shut that one down and went to OpenCPN--lo and behold-- it was receiving the GPS signal. Can't figure that one out!!
Thanks for any input.

gps can only be used by one app at a time,without a port emulator.

Re: GPS Receiver BU-353
You are in luck.
When you "suddenly" move the BU-353 a large distance, it must re-load the tables showing where the satellites will be at various times. On my BU-353, this requires either the START or COLDSTART when starting a new BU-353 or moving it a long distance.
When I got my BU-353 to replace a BU-303 that didn't work on XP, the 353 duplicated the 303 exactly - it didn't work either.
Lots of tracing and figuring and I found the GPSINFO program supplied with the GPS didn't properly work on Windows 7.
Called Globalsat - got a new version for Windows 7 - it didn't work either. They claim their version works - nonsense.
Anyway, plug in your GPS, load GPSINFO, see if a clean data stream is present and press COLDSTART. It will acquire in about 45 minutes if you have a clear view of the sky.
In the meantime, stay on XP. The inability to START my GPS if I move a lot or have some other problem makes it unacceptable for Windows 7.
I tried Cap'n, Coastal Explorer, and Open CPN - with no GPS data stream, neither of the 3 had any hope of telling me where I was.

Re: GPS Receiver BU-353
Kojiro, I think captstu means the "Coldstart" button in "GPSInfo" -the supplementary software he mentioned... If my memory serves, Sirfdemo (in Post 2) also has a "cold start" feature.

Re: GPS Receiver BU-353
Thanks to all those who offered their experience and expertise for the Bu-353. We now have the unit working on Windows XP with OPNCPN and Windows 7 with CMAP. I did not do anything special to make this happen and I´m not too savvy with electronic gadgets so I can´t offer any advise on how to make it work for others.
