The following modules can be used for a modem connection to a PC:
1. IL-NT RS232
2. IL-NT RS232-485
The RS232 interface uses COM1 port of the controller.
If you have trouble with modem communication, an additional initialization string may be required. This
may be due to, for example, a national telephone network-specific feature. Use the setpoint
ModemIniString to add the necessary AT commands which will be sent to the modem during the
initialization. See the documentation of the modem for details.
NOTE:
Use the same kind of modem (e.g. analog, GSM or ISDN) as used on the controller also on the PC
side.
Recommended GSM modems
Siemens/Cinterion M20, TC35, TC35i, ES75, MC39 (baud rate 9600 bps)
Wavecom M1200/WMOD2 (baud rate 9600 bps)
Wavecom Maestro 20
Wavecom Fastrack M1306B (Fastrack M1206B is not recommended)
Falcom A2D
Modem setup procedure
Analog modems obviously do not require any setup. The only case in which setup could be necessary
is if the modem has been bought in a country with a telephony system different than the target country
where the modem will be used.
GSM modems need to be set up prior to using them with the controller. Use the gm_setup program
(installed together with LiteEdit) to perform initial setup of the modem. See the latest Inteli
Communication Guide (available on the ComAp web site) for details. The setup must be done while a
SIM card is inserted.
NOTE:
It is always recommended to use modems bought in and approved for the target country.
Internet connection
A PC can be connected to the controller also remotely via Ethernet (internet, intranet). An appropriate
Ethernet communication module must be used.
Use a plug-in communication module IB-Lite or IL-NT-GPRS to connect to the IC-NT SPtM controller
via the internet. The setpoint COM1 Mode must be set to the DIRECT position.
