I am installing a new STng network with an es75 MFD, I70 instruments and a P70 control head. I would like to use my existing S2 course computer. Should I connect the P70 to the STng network via  spur cable and connect the S2 to the network using a ST1 to STng converter or would it be best to connect the p70 directly to the S2 and then connect the S2 to the network by way of the converter.

It would be best to connect the p70 to the S2 course computer via Seatalk interface, then connect both to the Seatalk NG backbone through the Seatalk to Seatalk NG converter.  This way if you needed to calibrate the S2 course computer the p70 being connected via Seatalk would be able to communicate with the S2 course computer via Seatalk and be able to calibrate the system.

Thank you. I should have confirmed before that putting the P70 on the ST1 network with the S2 just requires turning around a ST1 to STng cable, plugging the yellow coded end of the cable into the P70 and sending the ST1 end to the ST1 network. Do I have this right? Thanks again for your help.

That is correct.
