I have a seatalk box with st60 insturments and want to connect in a new raymarine 54e dsc vhf.

can I just connect the vhf into the nmea out on the sea talk box?

the depth is already externaly connected to the gps (garmin 152) via the sea talk box although acording to the seatalk interfase manual this doesnt need to be done as It shows the gps connected via the nmea in teminals.

ultimatly id like to connect all the insturments together and relay the info to my laptop via the rs232 out (I think)


is there anyone or place that has more detail on this setup?
thanks

Yes, you should be able to connect NMEA out to the NMEA in on your 54E.
Usually the (I assume) E85001 interface box only has 1 NMEA in, which is pretty stupid.

The RS232 connection to Laptop should also be easy.

RS232:
Windows Hyperterminal program.
Plug 2,3,5 pins. 5 being ground. if that does not work, swap pins 2,3.
4800 bps no parity, and one stop bit. i.e 8-None-1

GPS will feed 3 listening devices, 4 if you are lucky.

Is there any way around the single nmea ? is it possible to double up on this?

gps will go to vhf, computer and an autopilot
but to connect gps to interfase box and computer seems to double up on nmea in ?
any solutions , anyone?

thanks for the info but Im happy with the three devices at the moment -

however Im still a little un clear though how I actualy connect the three into one set of nmea + and- terminals, does it matter if I splice wires together or will this confuse information?

Nope, just bundle the three together in a chocolate block if you like.

This is my setup.
