Connecting control devices

The ECDIS CPU must be connected to a M570 or LTSX50 trackball for control.
Plug the trackball into either USB port - it will be automatically detected and enabled for use.

Keep spare sets of batteries on hand at all times.

The CAN bus

Device connection
The E5000 processors are equipped with a NMEA 2000 compatible data port, which allows
the receiving and sharing of data from various sources.
Essential network information
•
The standardized physical cables/connectors for the NMEA 2000 are 'Micro-C' and 'Mini-C',
directly derived from the automation industries 'DeviceNET' - 'Micro-C' being the more
commonly used size
•
While most Simrad products now use 'Micro-C' cabling and connectors, some products still
use proprietary 'SimNet' connectors, which are easily made compatible via adaptor cables
•
A network consists of a linear 'backbone' from which 'drop cables' connect to the CAN bus
compliant devices
•
A single drop cable has a maximum length of 6 m (19.7 ft). The total length of all drop cables
combined should not exceed 78m (256 ft)
•
A NMEA 2000 network using Micro-C cabling, has a maximum cable length of 100 m (328 ft),
between any two points
•
A NMEA 2000 network needs to have a terminator at each end of the backbone. A terminator
can be a terminator blank plug
Planning and installing a network backbone
The Micro-C backbone needs to run between the locations of all products to be installed -
typically in a bow to stern layout - and be no further than 6 m from a device to be connected.
Choose from the following components to make up the backbone:
•
Micro-C cables: 0.4 m (1.3 ft), 2 m (6.6 ft), 5 m (16.6 ft), and 9 m (29.5 ft) cables
•
T-connector. Used to connect a drop cable to the backbone
•
Micro-C power cable. Connected to backbone via a T-connector
¼ Note:
Most NMEA 2000 devices can be connected directly to a Simrad SimNet backbone and
SimNet devices can be connected to a NMEA 2000 network by using adapter cables.
