DSE Model 5210 Automatic Start Engine Management and Instrumentation System Operators Manual
8.3 ELECTRICAL CONNECTIONS TO J1939 ENABLED CONTROLLERS
This section of the manual is intended to describe only the connections between the 52xx controller and J1939
enabled controllers. All other connection details are described in the previous sections.
NOTE:- The CANbus specification, used by J1939, requires that a 120Ω terminator is fitted to each end of the
communications link. This termination resistor is fitted internally into the 52xx controller so is not required
externally. Ensure that the 52xx controller is the ‘last’ device on the communications link where more than one
device is connected to the engine ECU’s J1939 connector.
