InteliDrive Lite, SW version 1.9
ID-FLX-Lite-1.9r1 Reference Guide.pdf, ©ComAp – August 2015
11 Communication
NOTE:
Refer to InteliCommunication Guide for all additional information.
11.1 Direct cable connection
InteliDrive 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 InteliDrive Lite. In the area with electromagnetic
interefernece should be used shielded cables.
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).
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 38400 bps, via USB it is up to 115200 bps.
HINT
The RS485 communication line has to be terminated by 120 Ohm resistors on both ends. RS485 uses
channel COM2 in InteliDrive controller.
DIRECT CABLE CONNECTION TYPES
NOTE:
It is possible to create multiple controller connection through RS485. Be aware of controller address
collision. Manage address setting for each controller in setpoint Comms Setting: ControllerAddr
