Grounding — Dedicated drain wire
The power cable supplied with this product includes a dedicated
shield (drain) wire for connection to a vessel's RF ground point.
It is important that an effective RF ground is connected to the
system. A single ground point should be used for all equipment.
The unit can be grounded by connecting the shield (drain) wire of
the power cable to the vessel's RF ground point. On vessels without
an RF ground system the shield (drain) wire should be connected
directly to the negative battery terminal.
The dc power system should be either:
• Negative grounded, with the negative battery terminal connected
to the vessel's ground.
•
Floating, with neither battery terminal connected to the vessel's
ground
Warning: Positive ground systems
Do not connect this unit to a system which has positive
grounding.
4.4 JCU Connection
The JCU (Joystick Control Unit) can be connected as part of the
SeaTalk
hs
network. Alternatively it can be connected directly to the
thermal camera provided that there are no other camera controllers
on the system.
Connection to the SeaTalk
hs
network
The JCU is connected to the SeaTalk
hs
network via the PoE (power
over Ethernet) injector supplied with the JCU.

Cables
SeaTalk
hs
connection
Use a SeaTalk
hs
patch cable. These are
available in various lengths from your dealer.
JCU to PoE injector
Use the 7.62m (25') PoE cable supplied with
the JCU for this connection, if you require
a different length contact your dealer for
suitable cables.
Connection direct to camera
Direct connection is only valid if the JCU is the only controller and
there are no displays with the thermal camera application.
