HG EV-200 connection to my HS Network Switch???

Just bought a new Catamaran and I want to install a new autopilot (EV-200) that has a Seatalk HG connection... 4 wires from the Control unit ... Seatalk HG Plug at the other end... What do I need to connect in my Seatalk Network Switch # E55058... ???

Wil there be any communication issues with the E-120 Classic series MFP??
Help would be greatly appreciated!!!
