3 Overview
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.

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 HyQuest Solutions logger support application, iLink 2012.
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 3.4.2, 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 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.
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

iRIS 350FX Reference Manual V1.50
5HyQuest Solutions (NZ) Ltd - PO Box 9466, Hamilton, New Zealand Tel: [phone] Email: [e-mail]
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 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
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.

iRIS 350FX Reference Manual V1.50
6HyQuest Solutions (NZ) Ltd - PO Box 9466, Hamilton, New Zealand Tel: [phone] Email: [e-mail]
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.

iRIS 350FX Reference Manual V1.50
7HyQuest Solutions (NZ) Ltd - PO Box 9466, Hamilton, New Zealand Tel: [phone] Email: [e-mail]
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 6.2 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 HyQuest 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 the Section 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
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.
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.

I/O Connector
All I/O and power supply terminations are via 5mm (0.2”) pitch screw terminals provided on a 16-way
pluggable connector. The I/O connector is positioned on the right hand side of the iRIS circuit board, directly
above the white battery connector.
The function of each I/O termination is shown in the diagram below.
iRIS 350FX units fitted with a PCB revision V1.2+ have an 18-way connector compared to the 16-
way connector on earlier units. The two additional terminals provide an extra GND connection and
the 1-wire bus expansion port. They are shown as shaded in the diagram below.

Internal Battery
The iRIS is supplied with an internal rechargeable 12V 0.8A/Hr sealed lead-acid battery. Upon installation,
you will need to connect this battery as it is shipped disconnected to preserve battery life. It should also be
disconnected if the unit is not going to be used for some time.
For maximum flexibility, the iRIS I/O connector has two terminals provided for additional 12V power supply
flexibility. These terminals (marked 12V+ and GND) can either be used to deliver 12V from the internal battery
out to power an external sensor or other small load, or alternatively be connected to an external 12V battery
(for greater battery capacity) or a 12Vdc battery charger type power supply. See the next two sections on
using the 12V terminals and the external (charger) power supply feature.

WARNING! INTERNAL BATTERY
The 12V+ and GND terminals of the I/O connector are effectively connected directly in parallel with the
internal 12V battery. A resettable semiconductor fuse is fitted for short-circuit protection.
However, only connect 12V lead-acid batteries or a regulated d.c power supply that is designed for
charging a 12V lead-acid battery, to these terminals.
Applying a voltage higher than 14.5V for a sustained period to these terminals will permanently
damage the internal battery and may cause an acid leak and/or an explosion.

Internal/External 12V Battery Supply
There are two terminals provided on the I/O connector designated +12V and GND. These can be used to
power the unit from an external 12V battery or regulated dc supply. The internal battery is effectively
connected directly to these terminals. See Section 5.3.1 above for warnings on connecting external power
supplies to them.
External (Charger) Power Supply
Although the iRIS can operate solely from the internal battery for a few days if set to full power save mode,
you will typically need to connect an external supply to the unit so that the internal battery remains in a
charged state. You can connect any external dc power source ranging from 15 –30Vdc, including a solar
panel, without requiring an additional solar regulator.
The battery charging circuitry utilises a switch mode regulator for maximum efficiency. The external power
supply is protected against over-voltage by ultra-fast acting protection devices and a self-resetting
semiconductor fuse.
It can also be used to charge an external battery connected to the GND and 12V+ terminals. In the event
that the external battery draws excessive current, the charger will enter a current limit mode (900mA) until
such time as the battery has been recharged sufficiently to deliver the full supply voltage. The charging
profile used by the charger depends on the selected mode. See the Power Management description in
Section 6.3.2.
The battery charger operates in a simple dual mode “float” / “charge” pattern. To do this it regularly
switches between two voltage levels to optimise the battery charge. The actual profile is determined
by the Power Source setting.
When the Power Source is set to “DC”, the battery voltage will rise and fall every two hours giving a
“sawtooth” type voltage plot when the data is logged. This is normal.
Analogue I/O
Analogue Inputs
The four analogue inputs are uni-polar 0-5Vdc with 16-bit resolution. Each input presents a load impedance
of 97Kto the input signal.
Scaling factors should be chosen to convert from a raw value of 0.0000 –5.0000, which reflects the input
signal range of 0-5V. When current sources such as 0-20mA or 4-20mA are connected, an internal sink
resistor (100) is enabled by an internal user-settable link (J1-J4). In this mode the measured voltage range
is 0-2V for a 0-20mA input and the scaling factor should take this into account.
As the analogue inputs have an input impedance of 97K  , the actual sink resistor impedance will
be slightly lower than the value fitted. When, for example, the current mode link is fitted, a sink
resistor of 100 ohms is installed. The actual impedance will theoretically be 99.71  ; therefore the voltage
measured by the iRIS will also be slightly lower than expected. See Section 9for details on the
recommended scaling method for optimising the calibration.

Figure 3 - Simplified Analogue Input Circuit
Figure 4 - Analogue Input / Output Links
It is possible to use an external resistor such as a 250 Ωto raise the voltage range measured.
I.e. 100Ω will give a working range of 0.4V to 2V, 250Ω will give a range of 1V to 5V.
In this case, ensure the internal sink enable link is open. The resistor value in the analogue scaling
calculator in iLink will need to be changed to the value actually used.
Analogue Output
The iRIS has a single variable analogue output. This may be configured to deliver either a voltage output
ranging between 0-5V or a current output ranging from 4-20mA. The output's electrical signal (voltage or
current) is link selectable.
See Section 6.3.4.2 for details on configuring the analogue output.
Digital I/O
The iRIS has four digital I/O channels which can each be configured as either an input or output. When set as
an output, the channel can either supply switched 12V or else act as a pull-down switch for loads with a
different supply voltage. If the digital output configuration is set to 0 (Disabled) the channel is by default an
input. See Section 6.3.4.1 for details on configuring the digital outputs.
