Pin Out for MJ6 to RJ45 Network Cable

[Entropy]

I am in process of upgrading firmware on RPD-139 on an older boat located outside US. I need to make up a network cable to connect the Display (MJ6 6 pin) to Laptop with RJ45. No Furuno factory MJ6 to RJ45 cables on Island but have located a used MJ-A6SPF0014 with an MJ6 6 pin end and have standard Ethernet cables at the local Computer store.

It will be a direct connection between the laptop and the RPD-139 Display as there is no network hub. Therefore the cable will need to be a cross over.

Does anyone know the pin out for a cross over connection with MJ6 6 Pin and RJ45 Connector?

Thanks

Good morning Andrew,

Please see the diagram below that shows the pin-out of the Network port on an RDP-139.


You will want to make the following:
RJ45---------------------------------MJ6
3---------------------------------------1
6---------------------------------------2
1---------------------------------------3
2---------------------------------------4

Also below is a link to an update instruction document for Navnet 1
