I found you could get a 6' raynet cable off ebay for an almost reasonable price
When I received the cable, surprise! The actual wire between the connector was just a standard CAT5E shielded cable. So I cut it in two, and the ordered these keystone jacks.
Yes, there are six and I only needed two, but that's why I spent a bit more for CAT6 so i could use them in my house network as well.
Since the Raynet cable is using standard network wire... the colors matched up perfect with the wiring
diagrams on the tool-less keystone, so it was a breeze to connect. I used the T568B wiring
version, but it doesn't matter as long a the both keystone are wired the same. The only trick is remember to tuck the shield wire into the wire retention and make contact with the metal case of the keystone jack.
Then I just went down to the local cable store and bought a 25' shielded Cat5 cable for $12. Snaking it was easy and it CAT5 plug
went thru the pedestal
guard without a hitch. Just tape the connections in the binnacle to avoid water
Now I have chart sharing between the two MFDs... plus RADAR
at the binnacle. Woo-hoo!
