Waypoints are points you are to visit on a route i.e. change of direction, rest points, check-in stations. They might be entered by visiting them on a previous journey, most locations on a route where you might take a photograph are not waypoints although you could turn them in to waypoints. What you require the camera to do is accept standard NEMA phrases from the GPS Rx and use the location and time/date information from it. You could even set the clock in the camera using it, but since GPS time is UTC you might want to set your time zone in the camera. The GPS Rx does not need to be made to send current location information, that is why it is why it has a serial port (unless you change it from the default to transfer non-NEMA information). A 4800 Bd serial port is quite fast enough for this information, unless you imagine that your location is changing so fast that it needs updating at 480MBd; I doubt that a domestic GPS Rx could track the satellites at the velocity this implies. How many cameras are out there? Now how many GPS receivers are out there. Now is it more feasible to put USB on all the GPS receivers, or to put serial ports on all the cameras. You figure it out. How many of the cameras have USB host capability? The figure is between none and one, can you figure it out? Fortunately for camera manufactures GPS Rx manufactures have already agreed on a standard for presenting location information to other devices, it is a three wire serial port on a nine pin Dee with defined stop, start, parity, bit length and rate. The base rate is 4800, newer device have the option to select higher rates but will default to the standard. I can see that one change is required since a nine pin Dee is too large for most cameras. A better option would be Bluetooth, this would also allow remote control, both of the camera by the user and a flash by the camera. Bluetooth would certainly be better, serial is out of the question since it appears on very few cameras and would require yet another connector. I do not agree that fitting a camera that is designed to work with a GPS Rx with the established standard port for GPS communications is out of the question. It would only apply to the larger high end cameras, although a standard mini-DIN (like Apple) would be preferable to Dee, still if camera manufactures introduce it GPS manufactures would produce the cable. -- Ian G8ILZ |

In article , Mxsmanic writes Windows XP, since that was provided with the machine (I had to install it to allow connection of a USB peripheral, since NT would not support it and there was no supporting software for UNIX). You would not have all that trouble with an RS-232 port, in fact you could even use DOS (DR & MS), CP/M (80 & 86); in fact I doubt there're USB drivers for any of them. Manufactures should use standard ports instead of compelling you to use a specific OS. Or, you could just write your own driver for Unix. Isn't that supposed to be one of the great strengths of the OS? |

That may be practical for people with unlimited time on their hands, that might be an option, but not for most people. FWIW, you can write drivers for Windows, too, if you have the time and inclination. -- Transpose hotmail and mxsmanic in my e-mail address to reach me directly. |
