2.4.3. Building your NMEA2000 network
Multitronics CL-950E takes readings of parameters via the diagnostic line of the engine and transmits the processed data
to the NMEA2000 bus allowing to display this data on the screens of other devices (for example, a chartplotter) or to
create a network of several trip computers and ensure their simultaneous operation.
This technology gives advantage of integrating into the NMEA2000 network even those engines that do not support the
NMEA 2000 format (except J1939 protocol). Parameters of the engine operation of your water vehicle can be displayed
on a chartplotter.
To activate data transition into the NMEA2000 network proceed the following steps after Multitronics CL-950E has been
mounted and connected:
1. Turn on the chartplotter and wait till it is booted up.
2. Make to following changes to the settings of the device: “Settings display-Control-Conversion to NMEA-ON”
3. Turn off the ignition and wait till the screen of the Multitronics CL-950E is off then turn on the ignition (start the engine)
4. Select the engine parameters on the chartplotter according to its manual instructions.

2.4.4. Building the NMEA2000 network with several computers
When The Multitronics CL-950E is specified as the main computer it reads parameters from the engine
diagnostic line and transmits the processed data to the NMEA 2000 bus, which allows this date to be displayed
on screens of other trip computers thus creating a network of several trip computers and ensuring their
simultaneous operation.
Such parallel operation can be build up by one set of cables which connects the main trip computer to the
engine, other connections can be made with ordinary wires.

R1=120 ohm *
* When connecting several trip computers to each other, installation of at least one resistor R1 = 120 ohm is mandatory
otherwise computers will not work.
