Raymarine HS Network Connection cp100 sonar

[roetter]

I have a Raymarine system with:
Navstation:
e125, 2xi70, 1xp70 on stNG
Connected via RJ45-type Raymarine network hub to fly bridge:
e125, 2xi70, 1xp70 on stNG

Network hub has RADAR as well

Should I connect the CP100 to the network hub with the cable that converts from the new style round HS network connector to the RJ45 or use a cable with both ends new style round HS connectors and plug that from the CP100 directly into the second port at the NAvstation e125? Will I still be able to get the sonar to the fly bridge e125 if I plug the CP100 into the Navstation e125.
