3 Overview
3.1 Introduction
The iRIS 350FX (iQuest Remote Information Source) datalogger range has been designed as cost effective,
low power, self-contained information source for use in a wide range of data gathering and logging
applications.
The iRIS achieves network connectivity through the use of an integral wireless modem. Depending on the
version and target market, this modem will be one of the following:
Multi-band 900/1800/1900 MHz Wavecom 2406 or Q24+ GSM/GPRS in older iRIS 350 hardware.
Multi-band 3G HSDPA/WCDMA (for example Telecom XT® in New Zealand and Telstra NextG® in
Australia). This may be either a Maxon 6280E module in older iRIS 350 hardware or a Sierra
Wireless Q26 Extreme module in current production units.

3.3 Key Features
Terminal Diagnostics
A small number of diagnostic and initialisation options are available via a standard ASCII terminal
connected to the RS232 serial interface. In previous models (350 / 350X) nearly all the configuration was
also done using the terminal. This has been removed because of the increased features of the FX and data
unloading is done using the iQuest logger support application, iLink 2012.
Refer to Section 5.5 for details on the terminal options.
Wireless IP Connectivity
Wireless Internet Protocol connectivity is provided via the on-board modem. Through this interface it is
possible to perform configuration changes and retrieve logged data using HydroTel™ or iLink 2012
software. To facilitate IP connectivity, a suitably activated SIM card must be inserted in the device. It is
also necessary to program the unit with appropriate IP connection settings through a terminal connected to
the RS232 serial interface. The iRIS communicates using IP over a wireless network using either UDP or
TCP protocol.
Alternative Wireless Connectivity (SMS or FTP)
Another wireless connection mode other than IP is also possible on all hardware variants. This is SMS (Short
Message Service). As with the IP mode described above in Section 0, using the SMS service requires a SIM
card with the SMS service enabled by the service provider.
The SMS option works by sending a pre-set text message to up to ten destination cell phones or SMS
receivers. This message contains the iRIS site identification and the current values of all enabled sensors.
See Section 6.3 SMS Communication for more information on using the SMS feature.
Irrespective of the modem call-back mode setting (IP or SMS), the iRIS will only respond to
incoming SMS requests when it is not connected in IP mode. The modem call-back mode setting
only changes the service that is used to notify an alarm or generate a communications test. In
this case, the selected service and destination phone numbers are used to send a text message
(SMS).
Finally, FTP file transfer is provided for installations requiring a stand-alone data uploads. This option is
only available for units equipped with the Sierra Wireless Q26 modem.
Power Management
The iRIS supports four power management modes which are described below. Power management
features that operate in all modes include:
Deactivation of RS232 driver chip when the DSR signal is not present (unless the unit is active in
RS232 telemetry mode).
Turning off the backlight after a period of inactivity when no user is logged-in.
Ability to activate an IP session at scheduled times of day for pre-set period even if the modem is
otherwise disabled in full power save mode.

5iQuest (NZ) Ltd - PO Box 15169, Hamilton, New Zealand Tel: [phone] Fax: [phone] Email: [e-mail]
No Power Save
With power management disabled, the internal wireless modem is maintained in a powered on state
even if an IP 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 all status LED’s are permanently
enabled in this mode.
Partial Power Save
With the power management mode set to Partial Save, the on-board LEDs are disabled but the internal
wireless modem remains in the same fully active state as in the No Power Save mode.
Full Power Save
When power management is set to full save mode, the internal LEDs are disabled and the internal wireless
modem remains in a powered off state until a wireless session is activated by the scheduler, a user or an
alarm (if this feature is enabled).
While the modem is in this state, it is not possible to obtain signal strength measurements or
interrogate the modem via the AT command set using the Modem Terminal mode as the
modem is shut down.
RS232 Only
This mode is provided for applications where the internal modem is not used and telemetry is achieved by
a data radio or modem connected to the RS232 port. When in this mode, the RS232 port is used for all
call-back communication. The RS232 port behaviour also changes depending on whether the iRIS is in
“Normal” or “Telemetry” mode. See Section 0 6.5 RS232 Interface Telemetry for further details on RS232
telemetry communications.
Data Logging
The iRIS supports the logging of data from up to twenty virtual sensors. Each of the virtual sensors can
obtain information from one of the following data sources:
Analogue input on AIN1 –AIN4
Pulse counter attached to DIO1 - DIO4
Simulated pulse counter enabled by DIO1 - DIO4
Frequency counter attached to DIO1 or DIO2
Up/down counter attached to DIO1 and DIO2 simultaneously
Internal database location (for values obtained via user script or communications link)
SDI-12 instrument channel
Quadrature shaft encoder attached to DIO3 and DIO4 simultaneously
Change of status on charger input (dc supply)
Battery voltage
Supply (charger) voltage
Logger temperature
Received Signal Strength Indication (RSSI)
Derived via a lookup table (e.g. flow rate) sourced from sensor 1's measured value.
Change Of State on digital I/O channels DIO1 - DIO4

iRIS 350FX Reference Manual V1.30
6iQuest (NZ) Ltd - PO Box 15169, Hamilton, New Zealand Tel: [phone] Fax: [phone] Email: [e-mail]
Each sensor can be set up to scale the raw data source into engineering units through the application of a
multiplier and offset (slope and constant). The scaled value can be logged to non-volatile memory at rates
between once per minute to once per hour or immediately in true event mode for pulse inputs.
It is also possible to configure a sensor to also log associated values such as minimum, maximum, standard
deviation (for all source types) or a calculated flow rate or volume (pulse type sources only). See the next
section for further details on configuring these extended logging features as part of the Sensor Cfg menus.
Logged Data Array Identification
Each sensor’s logged data is identified by an array ID number. For the primary logged data, the ID is the
sensor number itself. For the optional supplementary data (min, max, deviation, flow/vol), the array ID has
an offset added to the sensor number that it is associated with. These ID offsets are as follows:
Minimum: +20
Maximum: +40
Deviation: +60
Flow/Volume +80
Check Count +100
For example, Sensor 4 has been configured to log the average value, plus the maximum and standard
deviation. Three data arrays will be logged for this sensor at each logging interval with IDs of 4, 44 and 64
respectively. In HydroTel™these require point identifiers of 4, 44 and 64 respectively.
Array 0 (zero) is a special array identifier and is used as a system event log. Currently this is only
used to log a restart (either at the initial connection of power, on a watchdog reset or a user
program start after an upgrade). The logged value in this case contains a value that can be
decoded to determine the cause of the restart. In HydroTel the identifier for this item is 0.
Alarm Processing
There is a “pool” of up to 40 free-format alarms. These can be assigned to any virtual sensor. So it is
possible to have up to two alarms on every sensor or else more on some sensors and less or none on
others. Each alarm has separate trigger and reset levels, and also an activation delay or accumulation
period depending upon the data type.
Each sensor has an associated flag that is set if any alarm on the sensor is active. This can be used to vary
the logging rate for the sensor. For example taking more frequent logs when water level is high compared
to a less frequent “routine” log in normal conditions.
The iRIS also maintains a global “alarms active” flag that is set if any alarm on any sensor in the device is
active. This is used to trigger a call-in or data transfer to the designated host. As well as the call-in, this flag
can also control the digital outputs or trigger a camera image for the iRIS-CAM variant.

Real Time Clock & Calendar
The iRIS has a non-volatile real time clock that can be read and/or synchronised using HydroTel™ or iLink
2012.
The iRIS 350FX differs from its predecessors in that the internal clock runs in UTC (GMT) and all
logged data is time/date stamped in this time zone. HydroTel™ and/or iLink 2012 automatically
adjust for this. The configured UTC offset is only used to adjust the date/times on the LCD (as
viewed by users) to the local standard time zone.
Security
The iRIS can be configured with a PIN code to prevent unauthorised access to restricted information
through the LCD and keypad. This is especially useful when the iRIS is installed in a location where it is
accessible to the general public.
A second level of security is also provided to prevent access to the terminal via a serial connection. This is
achieved by a security string that if used requires correct entry before access to the terminal is granted.
This is typically to protect the totalisers and logged data from being cleared.
See Section 0 for more details on using the security string.
Gateway Communication
The iRIS supports iQuest protocol gateway functionality between the wireless network and the RS232 serial
interface. This enables the unit to be used as a bridge between the wide area wireless network and a
localised radio or other network. It is possible to connect a datalogger that does not have wireless
capability such as the iQuest DS-4483 to the serial port of the iRIS and communicate with it via the
gateway. Also, by connecting a data radio to the unit’s serial port it is possible to communicate with
several devices in a multi-drop radio network from the wireless network.
When the gateway option is enabled, any data packets that are not addressed to the iRIS and match the
gateway criteria are readdressed and redirected. The port that the redirected packet is sent from depends
on the configuration of the iRIS.
Refer to Section 6.5 RS232 Interface Telemetry for further information on using the gateway.

4 iRIS 350X and iRIS 350FX Comparison
The iRIS 350FX is an enhanced firmware/software set that can be applied to any existing iRIS 350 or iRIS
350X datalogger. Primarily this update changes the fundamental datalogging format to floating-point and
is built around a new IEEE-745 2008 compliant library.
Aside from this many other functions have been reviewed and improved. The FX variant will become the
only firmware/software developed and supported in the future for the iRIS 350 hardware.
Because the changes are very significant, the upgraded iRIS 350 / 350X personality is a different model.
Key differences between iRIS 350X and iRIS 350FX
•Standard IEEE-754-2008 compliant Floating Point library.
•Datalogging sample values are floating-point. Logging multiplier removed.
•All timestamping is in UTC to enhance use internationally.
•Configuration via text terminal removed and only basic terminal diagnostics supported.
•SDI-12 firmware engine re-engineered and now fully compliant (retries etc).
•Supports a custom SDI-12 command with a separate schedule from measurements
•Default RS232 port speed increased from 38,400 to 115,200bps.
•Sensor logging rate can be different when alarm(s) on that sensors are active.
•All schedules have separate on/off/alarm intervals.
•Totalisers: YTD (Year To Date) and Last Year. Settable roll-over time (daily) or date (yearly).
•Capable of native FTP file transfer (CSV format) to one or two destinations.
(Requires Sierra Wireless Q26 modem)
•Analogue input ranges are now settable. Nine ranges provided between 0-80mV and 0-5V.
•Optional linearisation provided using a custom polynominal.
•Sensor display format is settable (number of decimal places).
•Support for up to two look-up tables for ratings / conversions.
Supports ad-hoc connection to IP host via extended SMS command (GOL )
•Multi-language support for internal date/times etc. Five supported (EN, DE, FR, ES, PT)
•Secure and reliable OTA (Over The Air) firmware and software upgrades now possible.

5 Installation
5.1 Opening / Closing the Housing
The front of the iRIS enclosure is secured by four M4 machine screws with Phillips® heads.
There are two small plastic hinges on the case. These are designed to hold the lid once it is
released.
To Open: Lift off the two grey plastic side covers to expose the screws securing the cover. Put them
in a safe place. Undo all four screws. There is no need to remove them completely as they are retained in
the lid. The front cover should then be able to be swung open, to a maximum angle of 90.
To Close: Check that the black sealing strip is fully installed in its retaining groove and there are no
wires likely to be trapped under the cover. Gently swing the front cover closed, holding it straight while
refitting the screws. Tighten screws securely to maintain the IP66 rating of the enclosure. Replace the grey
plastic side covers. Finally ensure the black rubber sealing cap is refitted to protect the RS232 connector.
5.2 Removing / fitting the SIM card
Important! Ensure the iRIS is depowered before attempting to remove or fit the SIM card. Exercise
care when inserting or removing the SIM card, as the carrier is fragile.
Open the front cover as described above.
Using a finger nail or small screwdriver inserted into one of the two oval holes on the sliding holder, gently
lower the slide downwards to unlock it. The slide can now be swung forwards from its top end to enable
the SIM card to be inserted or removed. Reverse the procedure to close and lock the card into place.

5.3 Terminal Connection
The iRIS RS232 port is a DTE (Data Terminal Equipment) configured port and is identical in pin-out and
signal allocation to that of an IBM compatible PC’s RS232 port. Therefore the cable required is the same as
that for computer-to-computer communication and is termed a null-modem cable. These are available
from most electronics retailers if required.
To access the iRIS diagnostic terminal a full null-modem cable (wired as shown below) between a
communication port (e.g. COM1) on your computer and the RS232 port of the iRIS. The null modem cable
configuration has the three main signal pairs crossed over. These pairs are TXD/RXD, RTS/CTS and DTR/DSR.
The signal ground (SG) line is connected straight through. The CD and RI lines are unused.
The iRIS RS232 serial port is set by default to a speed of 115200bps, 8 data bits, 1 stop bit and no parity.
Flow control is not required.

5.4 Terminal Security Code
The iRIS supports the use of a text-based security code (of up to 10 characters) that may be used to prevent
unauthorised access to the terminal menus.
If used, the code is set using iLink that is registered to “Administrator” level. If it is empty, the terminal is
immediately available as soon as the RS232 connection is made. If the code has been set, then a prompt
message is shown and the code must be entered before the terminal becomes available.
The security code is case-sensitive. The code cannot be viewed or changed except by an authorised
user using iLink which is registered to Administrator level.

Option 2 - Modem Diagnostics
Select this option to display the current modem identification parameters, status and signal strength. After
listing the status information, this option then provides a running diagnostic log of communication with the
wireless modem. Please see the next section for more details on the diagnostics that are available in this
menu option.
Modem Diagnostics
Example Status Information:
Modem Diagnostics. Enter 0 to exit
Modem: Sierra Wireless (W)
Version: R7.44.0.201007221223.Q26EX001 1608904 072210 12:23
IMEI: 351919030231951
IMSI: 530011102111028
LIP: 10.236.7.252
RSSI: -83 dBm BER: 0
Status: Connected
>
09:13:00 STATE: Connected PM1 SR0 LC1 LS1 PB CT60 CW179 LT60
IMEI: International Mobile Equipment Identifier. This is stored in the wireless module at the factory and
uniquely identifies the hardware by manufacturer and serial number.
IMSI: International Mobile Subscriber Information. This is obtained from the SIM card
LIP: The last local IP address that was allocated to the iRIS when it was last online.
RSSI: This displays the Received Signal Strength Indication in units of dBm. This is useful for determining
the strength of the signal. A value of 0 indicates that the RSSI value is not available.
The iRIS will not attempt to connect to the network if the RSSI is 0 or less than -113dBm.
Example diagnostic information. This will differ between units with either the earlier (Maxon
module) or the later (Wavecom or Sierra Wireless modules).
The < character indicates data received from the modem and the > character indicates data sent
to the modem.
The current communication state is shown with a preceding STATE: message that includes several
additional diagnostic e.g. PM1 SR0 TC0 TE0 TM0 LC0 LS0 PB CT3600. These are:
- PM Actual Power Management level being used. 0=No Save, 1=Partial Save, 2 = Full Save.
- SR Sync Request. (0 = clock in sync, 1=need clock sync from network)
- LC Link Control. Requested link control (to the modem module). (Wavecom only).
- LS Link State. Actual link state (from modem module). (Wavecom only).
- PB Current base (host) that is (or will be) connected. PB=Primary, SB=Secondary.
- CT Connection Timer. Connection time remaining. Set to duration when not connected.
- CW Connection Watchdog. Time before a hard reset of the modem is done. Is 3 times the
comms schedule interval. E.g. interval = 60 mins invokes reset if no connection in 3 hrs.
- LT TCP Server Listening Time (TCP mode only).

Option 3 - Modem Terminal
By using this terminal mode, it is possible to perform two distinct functions depending on the state of the
internal modem. If the terminal is available, this message is displayed.
> Terminal Mode active. Press <ESC> and then <Enter> to exit.
If the internal modem is powered down, the terminal mode is unavailable and this message will appear:
> Wireless module inactive. Terminal unavailable.
Assuming the modem is active, the two scenarios are as follows:
If the internal modem is powered up, but an IP session is not in progress, then it is possible to
interact with the modem using the standard AT command set.
If the internal modem is powered up and an IP session is currently in progress, then it is possible to
interact with a terminal at the remote end of the connection.
When using transparent terminal mode you must press the <Enter> key after each command or message
you wish to send. Press <ESC> followed by <Enter> to exit the modem terminal session and return to the
communication menu.
Option 4 - SDI-12 Terminal
The SDI-12 terminal mode allows direct access to instruments connected to the SDI-12 interface. This is
useful when a manual check or changes need to be made, such as address changes, scale factors etc.
Knowledge of SDI-12 commands is required to make use of this feature.
> SDI-12 Terminal mode active. Press <ESC Enter> to exit
Option 5 –Initialise
This option is used to initialise the unit. This is generally done just after installation as part of the
commissioning process to eliminate any test or residual data or totals. It resets the memory pointers to
zero and also resets all totalisers. To ensure this task is not accidentally invoked, a specific string must be
typed in order to execute the initialisation process.
> Type 'init' to initialise the unit

Table 3 - Status LED Indication Modes
Diagnostic LEDs
The iRIS has eight LED indicators that are useful for diagnostic purposes. These are visible through the
front of the enclosure.
With the exception of the SDI-12 TX LED, these indicators are only active when the power
management mode is set to No Power Save (see the Features Section 0for details on power
management).
DIO1 Illuminated red when Digital I/O #1 is active.
DIO2 Illuminated red when Digital I/O #2 is active.
DIO3 Illuminated red when Digital I/O #3 is active.
DIO4 Illuminated red when Digital I/O #4 is active.
RS232 RX Flashes green when data is received from the RS232 port.
RS232 TX Flashes green when data is transmitted out the RS232 port.
Modem Flashes green when there is receive or transmit activity to/from the modem.
SDI-12 Flashes green when an SDI-12 message is transmitted or received.
6.2 LCD & Keypad
LCD Operation
The iRIS LCD is controlled to optimise power consumption. If the display has powered down (in full power
save mode), the unit is in the lowest power mode and can be woken by pressing any key on the keypad.
After a certain period of no key presses, the display and backlight will power down again, although other
functions continue normally. If the user was logged on (PIN entered), they will be logged off. This version
of software has the timeout period set to 5 minutes.
