Introduction
Table 1 – feature list describing those available in each version
1.4.2 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.
1.4.3 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 activity – The status LED 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.
1.4.4 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 – 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 1
§ 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) (Only available on iRIS Under Cover Pro Version)
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.

Introduction
1.4.5 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:
+80
Flow/Volume
+100
Check Count
+120
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 84 respectively. In HydroTel™ or
SODA these require point identifiers of 4, 44 and 84 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.
1.4.6 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 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.
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.
1.4.7 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.

Installation
It is very important that the four retaining pins are locked installation to maintain the IP65 rating of the
enclosure.
2.2 Opening / Closing the Housing
The front of the iRIS enclosure is secured by four quarter turn locking pins with Phillips® heads.
§ To Open: Undo all four locking pins by pressing down with screwdriver and rotate a quarter turn in the anti-clockwise
direction. The pin has a spring, which eject the pin to the open state. The pins are retained in the lid. The front cover
should then be lifted away from the base, note there not any hinges so care should be taken not to place any stress
on the ribbon cable between the base and lid.
§ To Close: Place the lid on the base, ensuring the ribbon cable does not pinch. In turn, apply pressure to each pin so
that the spring is completely pressed, then turn clockwise a quarter turn until locked.
2.3 I/O Connector
All I/O and power supply terminations are via 5mm (0.2”) pitch screw terminals provided on a 12-way and 10- way
pluggable connector. The I/O connectors are positioned externally on each side of the logger enclosure to allow easy
unplugging of the logger. The function of each I/O termination is shown in the diagrams below.

§ External (Charger) Power Supply
§ Analogue I/O
§ Digital I/O
§ Serial Sensor Interface (SSI) (Pro)
2.3.1 External (Charger) Power Supply
The iRIS can operate solely from the external battery which is charged externally, or you can connect any external dc
power source ranging from 8 – 30Vdc, including a solar panel, without requiring an additional solar regulator.
The battery charging circuitry utilises a switch mode regulator, employing Maximum Power Point Tracking (MPPT) for
maximum efficiency. The external power supply is protected against over-voltage by ultra-fast acting protection devices
and a self-resetting semiconductor fuse.
The regulator can be configured to change different types of battery chemistry:
§ Sealed lead acid (SLA)
§ Lithium Ion / Lithium Polymer Batteries
§ Custom (user defined)
See section Solar Regulator for more information on configuration of the internal solar regulator.

Warning A cable length of lesser than 3m is required on the VIN port
Warning When using the charger feature of the logger an external battery needs to be attached. The input
supply must be connected to VIN and the battery connected to VBAT. When an external charger or DC
source is used this must be connected to VBAT and NOT VIN. In this case VIN should be left disconnected.
Failure to follow these instructions will cause the power to logger to drop out irregularly and it will reboot.

2.3.2 Analogue I/O
This chapter contains the following subsection:
§ Analogue Inputs
§ Analogue Output

© 2022 HyQuest Solutions 18
Installation
2.3.2.1 Analogue Inputs
The two analogue inputs are uni-polar 0-100mVdc, 0-5Vdc or 0-30Vdc with 16-bit resolution. Each input presents a load
impedance of 123.74 kΩ to the input signal.
Scaling factors should be chosen to convert from a raw value of, e.g. 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 Ω) is
enabled by an internal user-settable link. 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 123.74 kΩ, 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 99.92 Ω; therefore, the voltage measured by the
iRIS will also be slightly lower than expected.
Figure 6 – Simplified Analogue Input Circuit

© 2022 HyQuest Solutions 19
Installation
Figure 7 – Analogue Input / Output Links
It is possible to use an external resistor such as a 250 Ω to raise the voltage range measured.
I.e. 100 Ω will give a working range of 0.4V to 2V, 250 Ω 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. Also a voltage measurement range for the
analogue input range needs chosen instead of current.
2.3.2.2 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 Analogue I/O for details on configuring the analogue output.
2.3.3 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 Digital I/O for
details on configuring the digital outputs.
For more information, see the following subsections:
§ Digital Channels as Inputs
§ Digital Output (Pro)
2.3.3.1 Digital Channels as Inputs
The digital inputs are selectable for either mechanical or electronic operation. In either case it is necessary to pull the input
down to 0 V DC to activate it. Inputs will handle up to 30 V DC in the off state for parallel connection across existing
equipment. The “debounce” is enabled by a jumper link, which if fitted enables a longer time constant circuit to eliminate

multiple pulses caused by contact bounce. The debounce jumpers are positioned in the centre of the PCB. The picture
below shows the links in their default positions.
Figure 8 – Digital Input Debounce Links
Fit the jumper for mechanical switching at up to 20 Hz. In this mode the input is normally pulled up to 12 V through a 10
kΩ resistor providing a wetting current of approximately 1.2 mA. A 100 nF capacitor is also fitted across the input to
provide limited hardware debounce, preventing false triggering due to contact bounce.
Remove the appropriate jumper for electronic switching at up to 5 kHz. In this mode the input is normally pulled up to 5
V through a 57 kΩ resistance, providing a wetting current of approximately 100 µ A. When DIO is used as an input the
debouce circuit is permanently connected to the input pin.
Figure 9 – Digital Input Circuit
Important note!
In almost all installations where an iRIS is connected in parallel with other equipment to share a common
pulse input (e.g. from a flow meter), there has not been a detrimental effect, as the iRIS inputs present a
relatively high impedance to the circuit. However, in the event that connecting an iRIS does cause pulse
