Laptop Connections

PLease excuse what may seem to some as a stupid question.
I bought one of the GPS recievers for my laptop that uses 1 of the USB ports, works fine.
Then purchased Cmap-93 it says need to use RS232 serial port for GPS
Is there an adaptor for the serial port on my laptop to the USB end from my GPS???
Or is there another way around this?? Any help greatly appreciated
Thank you Heaps

Purchased? Why when you can get free....... and use with OpenCPN

What have you tried doing - sometimes instructions are junk.

If you need to, you can buy a USB to serial adaptor

If you Google "cmap-93 with usb" you will see some advice as to how to change the settings in Windows and in the Cmap set up, to get this to work without using a Serial Port.

google CNF.SeaSoft and download. You will need 7-zip or similar to unpack

To answer your original question...type "keyspan usb" into google and look at the shopping results.

There's nothing wrong with paying for the nautical charts you have. It always amazes me how many people are willing and eager to steal when it is "just" a downloaded file.

I posted the step-by-step answer to this the other day here First Post - Need Advice !

edit: Cancel the above -- I re-read your post... You just need to choose the serial port in in your program that corresponds to the Windows port assignment of your USB GPS.

If you don't know what that is, in Windows right-click on "My Computer" or "Computer", choose "properties", choose "Device Manager" and then expand the list of "ports".

This is true *if* the GPS provides a virtual serial port via the USB connection. Many do, but for example a Garmin GPS may be providing a "native Garmin" interface, which does not appear as a serial port.

There are ways around this (if this is the case), such as using GPSgate to do the conversion. But if your GPS supports it the easiest solution is as SailFastTri suggests. What brand / model GPS adaptor do you have?

G'Day MH1,

CM93 is just a set of charts, not a navigation program. So, I wonder what program you are using to display the charts? Very likely it is CmapsECS.

If so, you can go into the program's files and change things around. Look for a file called "Nmea.ini. Open it and look for an entry that looks like this:

[CHANNELS]
IN0=COM9: baud=4800 parity=N data=8 stop=1

Then change the "COMx:" to match your com port assignment, ie "Com4".

save the change and re-open the program. I think that it will now work.

Cheers and good luck.

G'Day Robert,

OK, you likely have a shortcut icon for cmapecs.exe on your desktop. Right click there and select "properties" from the menu that appears. This will bring up a window that includes the location of the file. On my computer it is found on the "C" drive. Go there and open the file. You should see a long list of folders and files, one of which is NMEA.ini.

And yes, Jon is a good guy and we think a great designer. At least, he got this one pretty right!

Cheers,

Jim and Ann s/v Insatiable II lyng Cairns, Qld, Oz, watching it rain.
