Remote control and data logging
Direct connection to the PC
InteliLite can be connected directly with PC via RS232 interface.
•
iL MRS15/16 is equpped built-in RS232 interface
•
iL MRS10/11 needs external RS232 interface AT-LINK-CONV (ordered separately)
Use the standard serial cable to connect PC with InteliLite.
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 resistor in controller burns out. The simple solution is to assure, that the PC
supply 240/20V is ground free (GND terminal is not connected).

PC software - LiteEdit
On the PC (for direct or modem connection) has to be installed the ComAp’s software package
LiteEdit. (based on Windows 95 or newer platform)
LiteEdit enables:
read the quantities
adjust all set points
control the engine
configure the controller
select software configuration
modify alarm inputs and outputs
modify password, commands protections
direct or *modem communication
Modbus protocol
The selection of the function of iL serial port is done via the setpoint
