Remote Control and Data Logging
Direct connection to the PC
InteliLite can be connected directly with PC via optional IL-NT RS232 interface.
Use the standard serial cable to connect PC with InteliLite.
Hint:
The communication setting for both communication ports on IL-NT controller is presetted
subsequently:
For MRS3 and AMF8: COM1 Mode is DIRECT – direct/internet communication
COM2 Mode is DIRECT – direct/internet communication
For MRS4 and AMF9: COM1 Mode is DIRECT – direct/internet communication
COM2 Mode is ECU LINK – protocol for communication with Cummins
engines via Modbus
Hint:
Make sure the grounding system on controller and PC – COM port (negative of the PC DC supply) are
identical – before the first direct connection. There must not be any voltage between these two points
otherwise the internal reversible fuse in controller burns out. The simple solution is to assure, that the
PC supply 240/20V is ground free (GND terminal is not connected).
