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.
