GPS NMEA Expansion

[pheelay]

Thus has aynone attempted to connbect there GPS unit to more than one
"listener", e.g. Altogether dCS radio, autopilot, laptop, radar, etc? If so, how was it done? With hardware "expander"? Interested in any experiences.

Thanks for the explanation, Meindert. You've consequently allayed my supsicions 1/two way.

To take this thread a step further, in my "junkbox" are 2 Delorme
Earthmate GPS receivers formerly used with laptop computers. For some reason, the output from these units don't convey location information to my radio. (I have not yet tried it with the autotiller.) My guess is that there's a baud rate problem. I'm not aware of adjustable settings on the units, which are said to be NMEA compliant, but it seems that there MUST be a way to switch from RS-232 to RS-422 in order to utilize the NMEA output feature. I've found Delomre tech support to be of absolutely no help with off-the-wall questions like this.

That's $250 US for a box with some connectors all wirenutted together inside. "Optically isolated" means you would not see the wirenuts! There must be a less expensive way...
