Note: It is possible to create multiple controller connection through RS485. Be aware of controller address
collision. Manage address setting for each controller in ControllerAddr (page 106).
Note: ComAp recommends using galvanicaly separated cable.
8.2 Remote connection
8.2.1 Internet connection
ID-Lite controllers can be monitored from PC tools as LiteEdit or InteliMonitor over the Internet using
InteliBridge-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 Group: Communication settings on page 106.
8.2.2 AirGate connection
ID-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 Group: Communication settings on page 106.
8.2.3 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, see Group: Communication settings on page 106: COM1 Mode
has to be set to MODEM.
Note: RF modem communication is also possible between controller and remote display.
Note: 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.
8.3 Modbus connection
Modbus protocol was implemented into the controllers to allow design of own supervision software offering
customer or to use ComAp SCADA software.
To learn more about Modbus interface see the training videos on Basic Modbus I and Basic Modbus II.
8.3.1 Modbus step by step
Use LiteEdit: Controller->Generate Cfg image->Modbus registers command to get registers list.
9600 bps, 8 data bits, 1 stop bit, no parity
Transfer mode RTU
Function 3 (Read Multiply Registers) max length of block is 127 registers
Function 6 (Write Single Register)
Function 16 (Write Multiply Registers) max 16 registers
The response to an incoming message is sent with minimum 4.096 ms delay after message reception
