Installation
– Verify that the requirements according to the SAE J1939 standard are still
met after installing the gateway (maximum number of subscribers, maximum
bus length, correct termination, …).
!
There is no additional or subsequent termination of the source data bus by means of the Gateway
ECU. If this is not ensured, the gateway must not be installed.
– Beforehand, make sure that the source bus operates with the correct data
transmission rate and that this matches the MCG’s data transmission rate.
!
If this is not the case, the gateway must not be installed.
– Check if the vehicle can provide an installation location in accordance with
see chapter "5.1 Installation location" on page 11.
!
If a corresponding installation location is not available, the unit must not be installed.
–
Check if additional specifications in relation to the installation of the ECU
exist from the vehicle manufacturer.
!
It is essential to comply with these during installation.
5.4
Testing the vehicle data bus
The MCG can only be installed on a CAN data bus that is based on the standardised SAE J1939
protocol.
– Test prior to installation whether the CAN source bus transmits data
according to the SAE J1939 protocol.
5.5
Checking the data transmission rate and selection of the
ECU variant
Two different parameter versions of the MCG are provided for the connection to a CAN data bus with
different transmission rates. The table below shows possible combinations.

As a next step it is therefore necessary to check which data transmission rate is used by the source
bus to which the MCG will be connected. The corresponding MCG variant must be used.
