Technical Handbook 59
The galvanic isolation ensures the safe operation of the connection, including between remote
devices and devices with earth potentials different from that of the HS315.
The length of the connection should be no more than 1200m; however, it depends on the
transmission baudrate set. A specific shielded cable should be used with grounded shielding
mesh.
To configure the use of the serial port 2 you need to configure the parameters
Parameter Description
P.0471 Use of serial port
P.0472 Modbus address
P.0473 Baud rate
P.0474 Settings
P.0475 Modbus registers order
The description of these parameters is found in document [3].
Using engine equipped with ECU (Electronic Control Unit) and CAN-BUS interface, most of
the previous detailed connections are no more required. With only one connection (CAN-BUS
to be more precise) the controller can start or stop the engine, as well as to control its speed,
to make several measurements (such as running speed, coolant temperature and oil pressure)
and to display the diagnose codes activated by the engine itself.
CAN-BUS connection is carried out by means connector JO. The same bus is also used for
connecting to the optional modules DITHERM, DIGRIN, DIVIT, DITEL and DANOUT.
The CAN-BUS interface of the HS315 is galvanically isolated.
For the connections described below, use a type of cable suitable for the CAN-BUS.
•
Connect terminal JO-5 to terminal CAN_H of the engine's control unit.
•
Connect terminal JO-6 to terminal CAN_L of the engine's control unit.
