ID-FLX-Lite-1.9r1 Reference Guide.pdf, ©ComAp – August 2015   
11.2  Remote connection 
11.2.1  Internet connection 
InteliDrive Lite controllers can be monitored from PC tools as LiteEdit or InteliMonitor over the Internet 
using Internet Bridge IB-NT connected to the controller via IL-NT RS232-485 port, via optional IB-Lite 
plug-in module or via IL-NT GPRS for cellular internet network. See Comms Settings. 
11.2.2  AirGate connection 
InteliDrive  Lite  controllers  can  be  monitored  from  PC  tools  as  LiteEdit  or  InteliMonitor  via  AirGate. 
AirGate technology is for easy plug and play wireless communication. Common SIM card with GPRS 
service is suitable for this system. It overcomes problems with special SIM card (fixed and public IP) 
necessity, with firewalls and difficult communication settings. For AirGate connection is possible to use 
IB-NT, IB-Lite or IL-NT GPRS modules. For setting see the setpoints in group Comms Settings. 
11.2.3  Modem connection 
PC can be connected to the controller also remotely via modems. Either an analog, GSM, ISDN or 3G 
modem must be connected to the RS232 interface. Setpoint Comms Settings: COM1 Mode has to 
be set to MODEM. 
NOTE: 
RF modem communication is also possible between controller and remote display. 
HINT 
In case of controller and remote display RF modem should be connected with serial cable with only 
three  connected  pins  Rx,  Tx  and  GND.  In  other  case  could  be  blocked  communication  between 
modem and controller. 
11.3  Modbus connection 
Modbus protocol was implemented into the controllers to allow design of own supervison software ofr 
customer or to use ComAp SCADA software. 
 
To  learn  more  about  Modbus  interface  see  the  training  videos  on
