Open array scanner cables for C-series displays
A split pedestal cable is required to connect a compatible open array scanner to
the display unit and to the power source.
If you are connecting an existing compatible scanner to a C-Series display a
pedestal adaptor cable can be used instead of the split pedestal cable.
CAUTION:
Do not extend the split pedestal or pedestal adaptor cable.
Split pedestal cable
The split pedestal cable combines the inter-unit and power cores, divided by a
Y junction. One core has a connector plug for connecting to the display unit, the
other core is for connecting to power. The scanner end is prepared ready to fit to
Section 2.2
the power and signal connectors (see ).
Two cable lengths are available:
• 25m cable provides 25m from scanner to Y junction.
• 15m cable provides 15m from scanner to Y junction.
These lengths should be sufficient to complete the cable run required on most
small vessels.
Pedestal adaptor cable
The pedestal adaptor cable combines the inter-unit and power cores, divided by a
Y junction. One core has a connector plug for connecting to the display unit, the
other core is for connecting to power. The scanner end has a connector plug for
fitting to an existing inter-unit cable.

ceive power from the display unit via the inter-unit cable. The display power cable is sup-
plied with the display unit and details for connecting power are provided in your display
unit Owner's Handbook. However, you should be aware of the information provided in this
section.
The DC system should be either:
• Negative grounded, with the negative battery terminal connected to the
ship's ground.
• Floating, with neither battery terminal connected to the ship's ground.
