As an alternative to the NMEA connectors you may use a CAN connection
box, (part number 406208A).
For a list of additional cables and connectors available from Cobham
SATCOM, see
Available parts on page 91.
If you are using a SAILOR 6194 Terminal Control Unit, refer also to the
manual
SAILOR 6194 Terminal Control Unit, Installation and user manual
[3].
3.2 Ground the units
Make sure you have a suitable grounding location for grounding the units,
preferably close to the power supply. See page 16 in the section
Location
of the SAILOR 3027 mini-C terminal .
3.2.1 SAILOR 3027 mini-C terminal
You may use a special CAN cable, containing only the power wires and
shield, to connect to the power supply. Using a T-connector, this cable can
be connected to the full CAN bus.
Connect the shield of the CAN cable to ship ground at the power supply.
Make sure the power supply has a good ship ground connection, e.g.
through the mounting plate and/or chassis.
Important The shield of the CAN cable from the terminal must be
grounded at the power supply,
not
at the terminal. This is to
ensure that any lightning strike at the terminal will be
directed straight to the ship ground, and away from
equipment operated by personnel.
