7.1 Direct cable connection
ID-Lite can be connected directly with PC via optional communication plug-in modules IL-NT RS232, IL-NT
RS232-485, IL-NT S-USB.
Use the standard serial / USB cable to connect PC with ID-Lite. In the area with electromagnetic interference
should be used shielded cables.
Note: 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).
The Setpoint COM1 Mode or COM2 Mode (according to the interface used) must be set to DIRECT position for
this kind of connection.
The communication speed of direct connection is up to 38400bps, via USB it is up to 115200bps.
Note: The RS485 communication line has to be terminated by 120 Ω resistors on both ends. RS485 uses
channel COM2 in InteliDrive controller.
