 help w/ NMEA wiring - Thom or others
Thom,
Here is a NMEA wiring question for you.
I have the following equipment:
ICOM M602
Furuno FCV 582L
Furuno GP 1700 w/ GPS
Furuno PG1000
I currently have to units interfaced without the PG1000 heading sensor. Reason is the GP1700 is the central point for all my connections and I think I am out of NMEA input ports unless you know a way to use the network port.
I am currently wired as follows: The GPS sensor connects to the GP1700 port 1. The 582 and 1700 talk on port 2 (input and output to each other)and the ICOM and 1700 talk on port 3 (input/output to each other as well).
What I havent figured out is how to interface the PG1000 heading sensor into this mix without loosing any functionality. It is my understanding that the PG1000 requires input as well as output. The input side of the equation is easy since the 1700 can output to multiple devices. But I dont have a dedicated port to input heading info to the 1700. If I used port 3 I would loose the DSC lat/lon pointout (TLL) on the 1700 display. Do you know if I can use the network port, and if so how??? Or do you know of any other way to wire this setup and get everything to work? I think I might need a nmea multiplexer or an RD30...???? HELP |
