Help with Seatalk on E120

[dpdash]

I have some very basic Seatalk needs. I currently have an E120 installed with the GPS125 hooked up via the Seatalk cable. I want to add some additional things onto the Seatalk "network". I purchased a 5 way Seatalk J-box. The picture below shows how the antenna is currently hooked up.

How do I go from the E120 to the Jbox, then connect the GPS125, Bidata40 guage and anything else in the future, ie VHF, etc?

Go with the colours on the E120; Red to Red, Yellow to Yellow, Black to Screen.

The GPS antenna is correctly wired for a Seatalk installation. The doubled-up wires could be used for a DGPS input. Since this is not the case, leave the GPS antenna wires as they are.

Or you could use a Seatalk extension cable, which saves stripping wires and crimping teminals.

Hope this helps.

The junction box you show is for Seatalk2, not SeaTalk.

SeaTalk is a three wire system, Red for power, Yellow for data, and Black for "data return" or ground. On the cable that connects to the back of the E, the other three wires are no shield = ground, Brown for Alarm return, and White for Alarm out. See page 30 of the E series installation manual at http://www.raymarine.com/SubmittedFi...s/e87043_2.pdf.

Do not use that junction box, and just connect the three wires from the bidata gauge by matching the colors as stated before.

Get a SeaTalk Aux Junction Box (R55006) to convert the bare wires of the RS125 to a SeaTalk plug. Then everything is "plug & play" using your Junction Block




Edit - Just saw Joe's post. The 5 way block works on SeaTalk OR SeaTalk2 (cannot mix). Documentation is bad on this fact, but I'm using the same block on my SeaTalk bus
