    SeaKing Sensor(S) in ARCNET through Twisted Pair The traditional method of transmitting Tritech data from Subsea to Surface is via a twisted pair cable. Connection to the V5 SCU should be made through the DA-15 connector, wired as below with any additionally networked heads connected in series off the first head.
  • Page 28 Power will need to be supplied to the sonar head through pin 3 (24V DC supply for a SeaKing) and pin 4 (0V ground) of the Tritech connector - the ARCNET port will not be able to supply this power and a suitable external source should be used.
  • Page 29 SCUv5 Communications Setup Seanet SCU v5 The connection to the SCU should be made through the ARCNET (DA-15) port and wired in the same manner as the ARCNET Through Twisted Pair shown above. Junction Box or Split AIF with RS232 Connection to the SCU should be made through the DA-15 connector.
