15.7 Focusing
Focusing of the camera can be achieved by screwing the lens clockwise or anticlockwise when viewing the
camera from the front. The camera is factory set to for midrange focus.
 Anticlockwise rotation (or screw outwards) focuses on near objects.
 Clockwise rotation (or screw inwards) focuses on distant objects.
15.8 iRIS Configuration
Once the camera has been installed and commissioned using the PC interface the iRIS needs to be
programmed and configured.
15.8.1 Installing iRIS Software for Camera Support
Installation of iRIS datalogger based software is achieved by using the iLink software package on a PC
connected to the logger via a null-modem cable. For details on how to upgrade the firmware and/or software
lease refer to Appendix F – Upgrading Firmware/Software. The only requirement for camera support is to
select the correct version for Program Bank 2. This is the file with the identifier “Cam” instead of the
standard variant which has the identifier “Std”.
e.g. iRIS350_GPRS_Camera_zzz_2.irs is the correct version for camera support on a GPRS version of the
iRIS 350.
15.8.2 Configure the Camera on the iRIS
As with a standard iRIS data logger all configuration is achieved through a terminal session with the logger
from a PC. This is done by connecting a PC to the logger with a null modem cable and connecting to it with a
terminal program like HyperTerminal. The list below describes the configuring of the settings that relate to
the operation of the camera.
