Linking VX1 to an auto pilot

[Anonymous]

I have a VX1 RDP-139 that I want to link to my new auto pilot. The autopilot has 2 wires a GPS + and - wires. I was hoping to get this info off the VX1 Data port 2 with a 6pin wire, but though further research I belive this has to come off a differant port. Right now Data port 2 and 4 are open, please tell me one of these will work? I have the unit hooked to a 6kw radar, a GPS sensor,Sounder module, and have the compass on it.
IF I can use 2 or 4 please include the info on which wire I will need and or which pin and how to figure out which pin is which to get this GPS data from/to. I currently have a 6 pin Furuno wire MJ-A6SPF0014-050 19S1015-0, if this wire is any help that would be great, as I already own it.

Thank you and such a great forum full of info and sharing people. I have realized this unit is very capable but also requires alot of knowledge and need to be a tech junkie to make it all do what I want.

Data 2 on the RDP139 is normally the preferred port to drive the auto pilot (using 6 pin NMEA cable 000-154-054..... White + and Black -)

I currently have a 6 pin Furuno wire MJ-A6SPF0014-050 19S1015-0, if this wire is any help that would be great, as I already own it.

I am not where I can cross reference the part number you have but if the cable isn't BLUE, then it should work fine.

Johnny, thank you very much for the reply. Exactly the info I was looking for. No need to cross reference as the cable is blue, so now to go find the right cable.
Thank you.

The blue cable would be a network cable (crossover) but you could make it work if you ohm it out and ensure you use the correct wires. You would need to take pin 1 (+) and Pin 2 (-) to drive data to the auto pilot.

How do you determine which pin is number 1? I hear it is next to some pin, or something like that. Also is pin 1 determined looking at the back of the unit so you have to cross it over to the female connector, or do you identify it on the cable?

 

[Johnny Electron]

If you hold the connector to the light the pins are normally numbered on the connector.

Johnny, thank you so much for the info.

Using the blue cable listed above I got out the ohm meter and here is what I found

1 = Blue
2 = White
3 = Black
4 = Brown
5 = nothing, maybe the foil wrap around the wires
6 = Bare wire

Obvously I need the blue and white wires for my connection, but maybe this can help someone else.

Thank you

A cut blue cable would match yours if they pick the correct end of the cable.
Being that it is a cross over cable and you don't know where the wires cross; a meter is the only way to know for sure. Thanks for sharing the pin-out.

Good to know that if you use my chart above you have a 50% chance of being right, and well that means you will be wrong 80% of the time, atleast for me I would be.

Thank you for your help.

Would these same pins and application work for a vx2 or is it different? If it is different which pins would I use and do you have a similar picture like above for reference of where the pins are located?

Thirty8ford-
The NavNet 1 and vx2 will be the same cable.

So than same cable and same installation of wiring terminals 1 and 2?

Yes
