6 Configuration
The iRIS configuration is done by iLink 2012 or HydroTel. A limited terminal tool is available via the RS232
port for local SDI-12 diagnostics.
This description assumes a computer running the Microsoft® Windows® operating system is being used and
all examples relate to the configuration tool in iLink 2012.
Terminal Connection
The iRIS RS232 port is a DTE (Data Terminal Equipment) configured port and is identical in pin-out and signal
allocation to that of an IBM compatible PC’s RS232 port. Therefore the cable required is the same as that for
computer-to-computer communication and is termed a
null-modem cable. These are available from most
electronics retailers if required.
To access the iRIS diagnostic terminal a full null-modem cable (wired as shown below) between a
communication port (e.g. COM1) on your computer and the RS232 port of the iRIS. The null modem cable
configuration has the three main signal pairs crossed over. These pairs are TXD/RXD, RTS/CTS and DTR/DSR.
The signal ground (SG) line is connected straight through. The CD and RI lines are unused.
The iRIS RS232 serial port is set by default to a speed of 115200bps, 8 data bits, 1 stop bit and no parity. Flow
control is not required.

Terminal Security Code
The iRIS supports the use of a text-based security code (of up to 10 characters) that may be used to prevent
unauthorised access to the terminal menus.
If used, the code is set using iLink 2012 that is registered to “Administrator” level. If it is empty, the terminal
is immediately available as soon as the RS232 connection is made. If the code has been set, then a prompt
message is shown and the code must be entered before the terminal becomes available.
The security code is case-sensitive. The code cannot be viewed or changed except by an authorised
user using iLink 2012 which is registered to Administrator level.
