The display uses a serial interface, otherwise known as a comm port. You can get a USB to DB9 adaptor practically anywhere. Once you have a serial connection, you will need software such as MaxSea to send the waypoint with.

I know this is an old question but just ran across it. The 1833C/NT is a radar and chart plotter. It requires the external and optional black box sounder to have depth recorder functionality.

A trick that I have found with the marine Furuno products is that they remember the state that they were in the last time power was removed from them.
In the unit is off when you remove the AUX power than when the AUX power is turned back on the unit will remain off.

If the unit was on when the AUX power was turned off then the unit will be automatically turn on when power AUX is turned back on

This feature keeps the unit alive if power is disrupted under way so that the helmsmen doesn't have to keep turning it back on during busy times.

You can interface the GP30 to the 1715 and get Lat/Lon readings where the cursor is. The GPS has extra wires in the power cable. The 1715 will require a NMEA cable pn 000-154-028. Connect the white GPS wire to the yellow radar wire and the blue GPS wire to the green radar wire.
