1 Introduction
1.1 About this Manual
This manual is intended as a detailed guide for iRIS 200 / iRIS 320 installation, configuration and operation.
For a brief operational overview, see the separate iRIS 220 Installation Guide or iRIS 320 Installation Guide.
This manual is also available online in Adobe Acrobat® pdf format for registered users at www.iquest.co.nz
NOTE: The term “iRIS” is used throughout this manual in all instances where the reference is
equally applicable to either the iRIS 220 or the iRIS 320. When a particular section applies to only
one of the models, the full model reference will be used.
NOTE: The term “GPRS/CDMA-1X” is used throughout this manual to refer to the wireless modem
connectivity. However, the terminal menus or LCD screens on the iRIS itself will display the correct
designation for the particular model e.g. “GPRS” or CDMA-1X”.
1.2 Hardware (PCB) Revision
As from firmware version 2.19 / software version 1.19, this manual has been completely updated to refer to
the new version PCB (V1.2). This hardware revision has the following changes over its predecessor:
• Two additional analogue inputs added.
• Dedicated 5V reference output for energising potentiometer type sensors.
• Digital Output 1 changed to a switched 12V output instead of open-drain pull-down. An external
transistor switch is not required for powering sensors.
• SDI-12 interface has been upgraded to full compliance with the SDI-12 electrical standard and to
free up the digital I/O that were required for the SDI-12 function on the older hardware.
Legacy I/O and SDI-12 details referring to the older PCB revision can be found in Appendix D – Legacy PCB
(Rev 1.1) Details.
