extension cable. The function of the RAT controls depend on which subsea sensors are
fitted, and the user should refer to the appropriate section of each product manual for full
details.

voltage is accessible on the DC OUT banana plugs on the rear.

disk on earlier Seanet SCUs is no longer used as there is an in-built factory restore option
for system recovery.

Note
The exact rear panel layout of the SCUv5 is subject to change and may not be
identical to the layout shown above.
For detailed pin-out diagrams and wiring options for the DE-9 and DA-15 connectors refer to
Appendix A, Data and Control Ports and Appendix B, SCUv5 Communications Setup.

The motherboard connectors are subject to change in line with Tritech
International Ltd policy of continual product improvement, however, this will not
affect ordinary operation of the SCU. Generally the motherboard will have USB

ports and RJ45 Ethernet.
Caution
If a DE-9 port is present on the motherboard it may only work with RS232 signals
but is not fitted with over-current protection. To avoid potential damage to the
motherboard it is recommended that this port is not used to connect sensor
equipment. Contact Tritech International Ltd with details of your SCU if more
information or assistance is required.
