Interfacing a CP180 chart plotter?

[nigelmercier]

I've just bought a Standard Horizon CP180 chart plotter. It has 2 NMEA inputs and 3 outputs, and I first planned to connect them to a PC and other instruments as follows:

NMEA Common: PC DB9 Pin 5
Port 1 Input: PC DB9 Pin 3
Port 1 Output: PC DB9 Pin 2
Port 2 Input: See below
Port 2 Output: VHF + NavTex
Port 3 Output: Other instruments

Then it occurred to me that I may be able to feed the other instruments back into the spare input, and get the wind and depth gauges to talk to it.

Any thoughts?

Seatalk and NMEA are not compatible unless you buy the Raymarine seatalk to nmea converter which is very pricey. Some later raymarine instruments do have nmea also.

Perhaps I'm jumping the gun saying SeaTalk, I just mean the other instruments which are on a bus with the repeater. I've amended my post.

What make are the other instruments?

Raytheon ST60 Wind, ST60 Depth, ST60 Tridata, Silva Star Nav Repeater.

Hmmm ... I've got a feeling I'm talking nonsense - perhaps it is only the repeater that is currently connected to the NMEA.
