CONNECT TO THE J1939 NETWORK
SAE J1939 is a common CAN bus standard. CAN buses are
used to connect the different sensors, monitors and other
electrical components of a machine, and digitally transmit
the required data in between those components.
The J1939 CAN bus works on a speed of 250 kbps. The
physical layer consists of four wires. Next to the two power
lines (VCC and Ground) there are two wires used for the
data transmission called "CAN High" and "CAN Low".
Before you start with the installation of the Link Up, we
strongly recommend to check the engine connector wiring
in the engine's manual and verifying your engine
connector wiring with a simple multimeter to ensure you
whether you have the right connector.
-
Turn off the circuit breaker and check the resistance
between the CAN High an CAN Low pins. The value
should lay somewhere between 60 and 120 Ohm.
-
Turn on the circuit breaker (for some models the
ignition also should be on) and measure the voltage
between the two Powerlines (GND and VCC). It must
be 12 to 24 Volts.
If possible, use the provided plug (shown in figure 2) to
connect the Link Up Gateway to your vessel. The contacts
must audibly lock into place.
If the vessels engine is not equipped with the matching
connector, it is possible to either crimp a female
counterpart on it (see "Technical Data"), or simply cut-off
the plug on the Link Up and manually connect the wires.
For this, refer to the pinout description, provided in the
section "Technical Data".
