need help with radar dome cable fitting

Hi
just installed the radar dome on the transom pole,all is well,BUT the cable going to the display must first run thru the pedestal rail from under the cockpit I believe is an Edson,by eyeball about 1 inch" about,will go back later and measure.
However when seating in the cockpit can tell the cable end will not go thru,again eyeball is about 1 1/4"
Will measure.
Radar is Garmin Gpsmap 942xs Display W/Gmr 18 Hd+ Radar Bundle.
What do people do,have an electronics tech cut and re splice connector end?
have a sealed thruhull?
kind of depressive.
thanks

Re: need help with radar dome cable fitting

You probably need to take the connector apart. All the pins should come out of the connector with some cleverness. Sometimes it's a tiny screwdriver to push in the lock tab on the pin. Sometime you need to make a tiny tube to slide over the pin to release the lock tab.

Re: need help with radar dome cable fitting

thank you Ecos
never thought always look at them as sealed endings?
worth a look,
Looks like an Ethernet type of connector but then follows a bulkier type of rubber like material.

Itís probably an Ethernet cable. Easiest approach is to cut the cable, run it, then rejoin it using crimp on (Ethernet jack crimper) waterproof connectors. Or you can save a few bucks and just crimp on regular RJ45 connectors, plug them into a connector joiner, and heatshrink it.

Re: need help with radar dome cable fitting

I believe Garmin sells a field installable connector (you also need an RJ45 crimper to install it.

Re: need help with radar dome cable fitting

not sure about cutting/crimping..
"a man got to know his limitations"kind of thing.
wonder if this may work?
before calling a electronics tech.

Hi Suijin
It is an Ethernet cable,checked the back of the display and is labeled ETHERNET.
Feel tempted to buy an extension with female/male ends and connect it,not sure how much will degrade the transmission but if it works will save a more expensive solution,like calling a tech,replacing the pedestal guard with a larger tube,the diameter on the plug is 1 3/16 and the tube is 1"
Could also just cut the ring with the treads and then tape to the displayt to make it water proof.

Re: need help with radar dome cable fitting

This is Ethernet cable, but not Cat 5. Cat 5 has 4 pairs while the radar cable has only 5.
Cut and splice is entirely feasible as long as you match the conduits correctly. I did this recently and have had no issues. Obviously you want good contact and waterproof casing. Won't be beautiful, but will work. Good luck.

Re: need help with radar dome cable fitting

I was faced with the same situation installing my Garmin radar with an Edison pedestal. After deliberating a while I cut the connector off and ran the cable. This was a new Garmin which came with a connector to use for just this situation. The crimp tool is readily available and the hardest part was making sure the correct color wires were in the required position. Make sure to keep the connector that came off and use it to match the colors/position. Takes a good eye to see the wire colors in the connector. I think younger eyes would have made my job easier. There's little down side to giving it a try if your comfortable with running the cable. If it doesn't work out with the connector crimp then call for help. Can also practice with a computer cable. Good luck.

You can even glue a terminal block to the inside back of the navpod and connect the wires that way. Makes it easy if you ever need to pull the cable...no plug to cut off again.

Navpods are not really moisture or waterproof but I know several people who have done it this way and had no problems after many years.

Re: need help with radar dome cable fitting

cut the end off and buy a new one. you'll need an standard rj45 crimper as well.

cut the one off at screen. leave the factory end at the radar as that one will get wetter.
