First be sure, by checking in "My Computer", which comport your GPS is REALLY using. My ancient(still has a 3.5 floppy drive and 2 serial ports) HP laptop
only has 3 USB ports
but lists my GPS as using commport 7 and the AIS
as using commport 8. Why is this? Beats me, but it is. I must also plug
both into the SAME USB port(ie the GPS goes in the port on the side of the 'puter and the AIS
goes in the upper of the 2 ports
on the back) every time or I confuse the 'puter and Seaclear.
Once you're sure which port your GPS is using open Seaclear, close the "cannot open port 1". Go to Tools(upper right), Properties, Comm. Be sure TxRx1 is set to the correct commport for your GPS and the rate is set at 4800 baud. Click SAVE. I have found that using a USB antenna
instead of a GPS with Seaclear works just fine and since I can't hook it into the chartplotter
on the boat
anyway, this works for me.
Once again, don't ask me how or why it works because I can't tell you. I CAN tell you it does. I can plot waypoints and routes using Seaclear by piddling around with the ROUTES menu until I remember how to do it.
Being a Ludite has its advantages although I can't think of any beyond not having to suffer through the first several incarnations of any given technology. Remember $500 digital watches?
Have fun and don't get frustrated. Seaclear does work and once you figure it out you'll love it...........martin
