ok..I'm just learning with the geeks...so ...if ..one GPS 'antenna' that outputs Seatalk, another that produces only the RF signal and a third that provides NMEA LAT/LON....this means..that you can approach coast line...only using ground stations...so...you go dark...15 minutes...than you receive a signal, retrieve to the mother network, 7 to 7 seconds (something like this...) and finally use stupid mobile phone ground antenna...hum...I'm just trying to think by my own..

create our own channel...receive GPS info, from a third party...

....Experience !!! ....Try this ....

purchased a cheap GPS designed for cars. It is a LAN type frequency 1575.42 MHZ Voltage 3.0-5.0 V. It worked fine and even inside the vessel. (I have a composite hull and not a steel hull. So there was no need to run an external wire out. The one complication here was cutting the termination off and connecting it to an adapter to connect into the Comar...
reused an exisiting VHF antenna and simply purchased a new cable. .... attached terminals for this cable ... needed another adapter to connect to the back of the Comar.
running a Windows 10 laptop and connected to my USB port using a USB to Serial Adapter. ... called IOCREST and the brochure didn't claim it was compatible with Windows 10..... I found something similar on Amazon
get a nine pin cable male to female to connect the adapter to the back of the Comar.
power cable ...Be sure to indicate how many pins are on the power cable...or..powered the unit up as follows...a small cable and cut it 3 inches long and pulled out a few strands of copper wire. This allow... to slide the small cable onto the pins. If you attempt this, do not cross connect plus and minus. As you are looking at the back of the device, the pin that is on your right hand side is the positive pin. This can be confirmed using an tester. If you touch the left pin and shield for the VHF cable or GPS cable ... you will notice that the two are in common.
downloaded the PROAIS software ...
able to get the CSB200 to show ships live on my Open CPN. One thing to remember is to turn off the ProAIS software for ships to show up.
