NOTE
If the module has been configured so that one of the three pickup signals is not used, the LED corresponding to
this signal will never be lit.
Communications
The ignition module has two options for communicating with other equipment. Both communications protocols
have the same possibilities as regards control and reading capacity:
-
2 CANbus 2.0 communications ports: the unit can communicate with the other equipment by means of
two different CAN protocols: CANopen and J1939. We can use the configuration menu to choose one
protocol or the other. The CAN connection allows a maximum cable length of 250 metres.
-
1 RS-485 port for connecting to a PC or Modbus communication with other equipment. The RS-485
connection allows a maximum length of 100 metres.
NOTE
With GCS-E panels, communication with the other equipment is carried out through the CAN port using the
CANopen protocol.
NOTE
The ignition module can be connected to the PC in two ways: via the USB or RS-485 ports. To activate said port,
please contact Kohler.
PC Connection
The ignition module can be connected to the PC in two ways: via the USB or RS-485 ports.
However, the firmware to connect the unit via the USB port does not let us connect it via the RS-485 port and vice
versa. This means that the firmware version of the unit has to be changed to change the port used to connect to
the PC.
NOTE
With Kohler engines, the units are pre-programmed for connecting to the PC via the USB port. The maximum
USB cable length allowed is 5 metres.
Potentiometers and reset button
The unit has two potentiometers to adjust the advance: one for ignition schedule A and the other for ignition
schedule B. With Kohler engines, the option of adjusting the advance using these potentiometers is disabled
(only A).
The reset button completely resets the unit. With Kohler engines, this reset is carried out via communications,
either from the GCS-E panel display or from the GIS unit display.
