Note: Unlike the Ekinox surface version the subsea one doesn't provide Sync In C signal. However,
please keep in mind that the synchronization input signals are not hard linked to a serial port.
Note 2: The enclosure is isolated from the electrical grounds. The power and data ground are
internally connected but their pinout must be respected for forward compatibility
Warning: For previous Ekinox Subsea units with product codes EKINOX-#-G4A1-PS-E#-I#, the Sync
In C signal was available instead of the Sync In D.
Please not that it will only impact the Ekinox software configuration as no electrical modification
has been made.
