2.8 Key Features
2.8.1 Terminal Configuration
All configuration and set-up parameters are modified via a standard ASCII terminal connected to the RS232
serial interface. This means that the user can configure the device without needing specialised configuration
software installed on their computer specifically for this purpose. iQuest also supply a network based
terminal program (UDPTerminal) that allows set-up to be performed across the GPRS/CDMA-1X network via
ASCII socket A. Refer to Section 4.2 for details on the terminal setup.

2.8.2 Wireless IP Connectivity (GPRS/CDMA)
Wireless Internet Protocol connectivity is provided via an on-board modem. Through this interface it is
possible to perform configuration changes and retrieve logged data. To facilitate GPRS connectivity with the
GSM models, a suitably activated SIM card must be inserted in the device. For all models, it is also
necessary to program the unit with appropriate GPRS/CDMA-1X connection settings via a terminal
connected to the RS232 serial interface.
The iRIS communicates over a GPRS or CDMA-1X network using UDP protocol via two concurrent data
ports. Port A is used for ASCII communication and provides similar terminal functionality to that available
through the RS232 serial interface. Port B is used for proprietary System DO

2.8.3 Alternative Wireless Connectivity (CSD/SMS)
Two other wireless connection modes other than GPRS/CDMA-1X are also possible. These are CSD (Circuit
Switched Data) or SMS (Short Message Service). As with the GPRS/CDMA-1X mode described above in
Section 2.8.2, using either CSD and/or SMS requires either a SIM card with relevant services enabled by the
GSM service provider, or in the case of CDMA-1X, the appropriate services enabled by the CDMA provider.
The CSD option is achieved by establishing a dial-up modem connection across the GSM or CDMA network.
Once this link is connected, data retrieval and configuration can be performed in a similar manner to the
GPRS/CDMA-1X mode.
The SMS option works by sending a preset text message to up to two destination cellphones or SMS
receivers. This message contains the iRIS site identification and the current values of all enabled sensors.
See Section 5.3 for more information on using the SMS feature.
NOTE: No matter what the modem callback mode is set to (GPRS/CDMA-1X or CSD or SMS), the iRIS
will answer any incoming CSD calls and also respond to incoming SMS requests as long as it is not
connected using the wireless IP link. The modem callback mode setting only changes the service
that is used to notify an alarm or generate a communication test. In this case the selected service
and destination phone number is used to call a base modem (CSD) or send a text message (SMS).

2.8.4 Power Management
The iRIS supports three power management modes:
No Power Save
With power management disabled, the internal wireless modem is maintained in a powered on state
whenever a GPRS/CDMA-1X or CSD session is not currently active. While in this state, periodic signal
strength measurements are made and it is possible to interrogate the internal modem using the AT
command set via a terminal connected to the serial interface.
All on-board communication, I/O and status LED’s are permanently enabled in this mode.
