CONNECTION	TYPE	FUNCTION
Tether Whip (View Specifications)	8 pin round male	Used to connect the ROV to the tether for power, communications, video and accessory support.
Accessory Port (Specifications listed below)	9 pin rectangular female	Provides power, communications and video. Can be used to connect accessories electrically to the ROV.

Accessory Port

The ROV accessory port provides power, access to the ROV communications bus and the APIC (Auxiliary Pair of Independent Conductors) to the surface. Most accessories, with the exception of the manipulator and cutter, use a stackable pass through connector that allows multiple accessories to be connected to the accessory port in parallel.

The accessory port must be sealed with a terminated accessory connector or the accessory port terminator dummy plug. Failure to seal the accessory port may lead to loss of control of the ROV or damage to the components.
