9.1 SeaTalkng ® power supply
Your product is supplied power via the SeaTalkng ® backbone.
A SeaTalkng ® backbone requires a single 12 V dc power supply. Power can
be supplied to the SeaTalkng ® backbone by one of the following methods:
•
(1)
direct connection to a 12 V dc battery using an inline 5 amp fuse,
• connection to a 12 V dc distribution panel using a 5 amp thermal breaker,
• (2) connection to the SeaTalkng ® connector of an Autopilot Control Unit
(ACU) (not ACU-100 or 150), or an SPX course computer (not SPX-5).
• for 24 V vessels, connection must be via a 5 amp, regulated, continuous
24 V dc to 12 V dc converter
Note:
• (1) The battery used for starting the vessel’s engine(s) should NOT be used
to power the SeaTalkng ® backbone, as this can cause sudden voltage
drops when the engines are started.
• (2) The ACU-100, ACU-150 or SPX-5 products cannot be used to power
the SeaTalkng ® backbone. The ACU’s/SPX’s SeaTalkng ® connector
has a power switch that must be in the on position to provide power to
the backbone.
Inline fuse and thermal breaker ratings
The SeaTalkng ® network’s power supply requires an inline fuse or thermal
breaker to be fitted.
Inline fuse rating Thermal breaker rating
5 A 3 A (refer to note below)
Note:
The suitable fuse rating for the thermal breaker is dependent on:
1. How many devices you have connected to your SeaTalkng ® network,
and;
2. How many devices are sharing the same thermal breaker that your
SeaTalkng ® network is connected to.
9.2 SeaTalkng ® power cables
The following SeaTalkng ® power cables can be used to connect the
backbone to your chosen power supply:
Direct connection cables
1. Power cable (straight) 2 m (6.6 ft) (part number: A06049 ).
2. Elbow (right angled) power cable 2 m (6.6 ft) (part number: A06070 ).
Autopilot Control Unit connection cable
1. ACU / SPX autopilot to SeaTalkng spur cable 0.3 m (1.0 ft) (part number
R12112 ). Connects the course computer to the SeaTalkng backbone.
This connection can also be used to provide 12 V dc power to the
SeaTalkng backbone.
9.3 SeaTalkng ® product loading
The number of products that can be connected to a SeaTalkng ® backbone
depends on the current draw of each product and the physical length of
the backbone cabling.
NMEA 2000 Load Equivalency Numbers (LEN) are used to express the
amount of current that is drawn from SeaTalkng ® products (1 LEN = 50
mA) The LEN for each product can be found in the product’s Technical
Specification.
