Introduction
1Introduction
Thank you for choosing our product. We hope you will enjoy using the device.
HyQuest Solutions manufactures, sells, installs and operates quality instrumentation, data loggers and communication
technology. Products are designed with passion for environmental monitoring and with a deep understanding of the
quality, accuracy and robustness needed to fulfil the requirements of measurement practitioners in the field.
The present User Manual will help you understand, install and deploy the device. If, however, you feel that a particular
information is missing, incomplete or confusing, please do not hesitate to contact us for further support!
The iRIS 270 is the perfect marriage of the proven iRIS design legacy with a future-proof architecture. It is compact, cost
effective, ruggedized, IP-capable and easily configured - and due to its dual telemetry slots the iRIS 270 extends the
telemetry options and the range of pluggable devices.
General Characteristics
The iRIS 270 is supplied in an environmentally sealed (IP67) enclosure constructed from a special corrosion-resistant
aluminium alloy that is finished in a hard-anodised coating. This provides a very high degree of mechanical strength and
EMI shielding, and enables completely stand-alone mounting in outdoor situations.
The iRIS 270 supports a maximum of fifty external sensors (1-50). Sources for these sensors may be chosen from physical
digital or analogue inputs or virtual sources (via serial communication or calculations).
Sources may also be from internal measurements (battery voltage, supply voltage, temperature and RSSI). Each sensor
has six associated alarms, each with separate trigger and reset levels. Each alarm also has a duration, which is used to
delay the alarm trigger for analogue inputs and to determine the time over which pulse input counters should be
totalised (rainfall etc.).
Data from all enabled sensors are logged format which includes full date and time stamp to a 1 second resolution. The iRIS
270 supports SDI-12 communication with a range of industry standard intelligent sensors.

§ About this Manual
§ Key Features
1.1 About this Manual
This manual is intended as a detailed guide for iRIS 270 installation, configuration and operation.
This manual is also available online in Adobe Acrobat® pdf format for download at www.hyquestsolutions.com.
Throughout this document, small icons are used to identify additional information. These are as follows:
Note Indicates extra detail to expand the current discussion.
Warning Describes something that may cause problems if not heeded.
Note: The term “iRIS” is used throughout this manual in all references to the iRIS 270.
1.2 Key Features
This chapter contains the following subsections:
§ Telemetry and SDI-12 Diagnostics
§ Power Management
§ Data Logging
§ Logged Data Array Identification
§ Alarm Processing
§ Real Time Clock & Calendar
§ Security
1.2.1 Telemetry and SDI-12 Diagnostics
Monitoring operation of the communications modules and SDI-12 bus is possible from the iLink software. The
Architecture allow for remote monitoring, monitoring over open channels (Radio) even monitoring of the operation of
the channel being used. The information obtained is time stamped real time log with three levels (information,
warning/error), which this can be filtered and captured for later analysis.
1.2.2 Power Management
The iRIS supports power management in two main ways. These can be used to save power for sites that have a small
power budget:
§ LED and LCD activity – The status LED and LCD backlight can be set to turn off after a user defined timeout.
§ Checking SMS on Cellular module – the checking for incoming SMS can be disabled to save power.

Introduction
1.2.3 Data Logging
The iRIS supports the logging of data from up to fifty virtual sensors. Each of the virtual sensors can obtain information
from one of the following data sources:
§ Analogue input on AIN1 – AIN2
§ Pulse counter attached to DI1, DI2 or DIO
§ Simulated pulse counter enabled by DI1, DI2 or DIO
§ Frequency counter attached to DI1, DI2 or DIO
§ Up/down counter attached to DI1, DI2 or DIO simultaneously
§ SDI-12 instrument channel
§ Change of status on charger input (dc supply)
§ Battery voltage
§ Supply (charger) voltage
§ Logger temperature
§ Received Signal Strength Indication (RSSI)
§ Change Of State on digital I/O channels DI1, DI2 or DIO
§ Serial instrument (using the Modbus protocol)
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 Configuration menus.
1.2.4 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:
+50
Maximum:
+100
Deviation:
+150
Flow/Volume
+200
Check Count
+250
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, 104 and 154 respectively. In HydroTel™ or
SODA these require point identifiers of 4, 104 and 154 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.
1.2.5 Alarm Processing
There is a “pool” of up to 100 free-format alarms. These can be assigned to any virtual sensor. It therefore possible to
have 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, an activation delay or accumulation period depending upon the data type, comms interval,
enable call-in and an option to send a customised SMS text to a specified number when the alarm is triggered.

Introduction
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.
1.2.6 Real Time Clock & Calendar
The iRIS has a non-volatile real time clock that can be read and/or synchronised using HydroTel™ or iLink 3.
1.2.7 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.
