Chapter 4: Display Unit
Primarily, the display unit activates and deactivates dosimeters, and provides an immediate
digital readout of an exposure. The display unit initiates all communication between the
display unit and the dosimeter, and works by emitting a field of RF (radio-frequency) energy
(13.56 MHz) that powers up the dosimeter and allows the unit to interact with the dosimeter.
At the time of read out, an exposure record is logged into memory on both the dosimeter and
the display unit.
The display unit must be charged and configured before using Aurion for the first time. During
the configuration process, Landauer downloads software from Landauer’s web site and installs
the software on your computer.
Exposure records on the display unit can be transferred to Aurion’s database on Landauer’s
web site for data management. During the data transfer process, Landauer downloads software
from Landauer’s web site and installs the software on the computer used to transfer data from
the display unit to the web site.
Charging
Charge the display unit for a minimum of twelve hours before use for the first time. Plug in the
charger and place the display unit into the charger to automatically begin charging. Retain the
display unit when not in use in the charger to maintain charge. If the display unit is idle when
out of the charger for the default of ten minutes, it automatically shuts off to save power.
Turn on the display unit for use by pressing any key on the unit. Turn off the display unit by
sliding the unit out of the charger and pressing the function key [F4] and then the [0] key.

If you are setting up your computer for the first time, refer to the setup instructions for your
computer. Turn off your computer when connecting any cables, connect the cable, and
then turn on the computer.
Alternately, you may supply and connect an Ethernet patch cable with a RJ45 connector
on each end directly to the display unit and then to a RJ45 female to a supplied DB9
female adapter that you can connect to your personal computer COM port for communication.
