Ok, here is what's going on
Hello, I have a Factory installed E120 and E80 but do not have the schematics for the SEATALK HS connection between them.
Does anyone knows how Hunter connects them? I do not see any network switch, maybe a "homemade" crossover cable?
Thanks
Miguel
You have raymarine Classic e120 & E80 units.
The HS link is an ethernet -type connection, but it is not ethernet per-say.
It is a proprietary Raymarine communication protocol.
There are 2 ways that your E units can be connected together. Yours is connected as follows:
Between the 2 units is an 8 conductor ethernet-type cable.
But, the units have a cross-over coupler connected between them.
You cannot connect 2 E units directly to each other, as you need to swap the Tx and Rx connections.
So, behind the E-80 at the Nav desk you'll find a small black coupler which is the cross-over
The other way you can connect the 2 units together is through ports on a Raymarine HS Switch. It's basically an ethernet switch.
This was not needed with the Classic E series, because the radar is an analog dome.
In other words, on the back of each E classic display is a dedicated radar connector.
Once you get into the newer E series, such as the E-wide, the radome is on HS. Therefore, it does not plug into the display anymore. The radome plugs into a HS switch, because the radome is digital.
And each E-wide display plugs into ports on the HS switch.
I hope this explanation is satisfactory.
You can look at Raymarine's site for wiring diagrams.

I have a 49, and have a suggestion for you.
I know this is going to cost money, but it's worth it.
Get rid of your E Classic displays, and upgrade to the newer models.
You will need to change your radome as well.
The pan and zoom on the E classics is HORRIBLE.
I was never so disappointed in gear as I was with the E classic displays.
