2. Description
2.1. Product Description
Both of these hands-free readers are interface hardware which provide a centralized system
(DOSICARE, DOSISERV and SENTINEL or configuration software (such as DMCUser)) to
communicate with DMC 2000, DMC 3000 and SOR dosimeters.
The LDM 320 is connected to a USB port of a PC. It is available in two versions:
Desk version (LDM 320D):

2.2. General Reader Operation
The dosimeter reader is connected to a "host" PC through a USB link.
Users operate the reader by computer via a USB cord. Most commands are intended for
communication with a dosimeter present in the reader coverage area.
Dosimeter reader typical use:
"Office" use: The reader is used to configure the dosimeters and ommunicate to the PC
the dosimeter's stored measurements and event histories.
"Access control" use: The reader is used to identify presented dosimeters, check them
for good condition, switch them to "Measurement" (Run) mode at "area entry" and to
"Pause" mode at "area exit", and retrieve their essential data (doses, dose rates, etc.).

2.4. Reader Operating Modes
The reader has several operating modes. Switching from one mode to another is done via
computer. Upon power-on, the reader starts in the mode indicated by the associated
configuration parameter.
The following modes are available for use:
Normal mode
Specific mode
"Test" modes
Downloading and Programming mode

2.4.1. Normal Operating Mode
This is the reader operational functioning mode. In this mode the reader operates as a slave
to the PC:
It retrieves the PC commands.
It searches for dosimeters.
It runs the commands (reading or writing dosimeter information or parameters).
It sends a report to the PC.
2.4.2. Specific Mode
This mode is reserved for specific autonomous applications.
2.4.3. Test Modes
These test modes are intended to check reader integrity (Factory use only.)
"Antenna tuning" test mode
"AGC programmable amplifier" test mode
"Autonomous" test mode
MMI and digital input/output test mode
2.4.4. Downloading and Programming Mode
This mode is used to update the reader firmware (Factory use only.)

3. Installation, Connection and Start-up
Keep the reader away from sources of electromagnetic fields
(f = 125 kHz: video terminals, power supplies, rotary machines, etc.).
Install readers in accordance with §4 recommendations.
To install and start up the LDM 320, take the following steps:
Install the software on the PC.
Connect the reader to the PC.
3.1. Hardware Installation
The LDM 320D does not require any installation as it only has to be placed on a desk
and connected to a PC through a USB cable.
The LDM 320W must be wall-mounted through the support plate. It is also connected to
a PC through a USB cable.
The USB cable can be positioned as follows:
by passing it behind the reader, through the partition by drilling a hole for this purpose, or
by passing it outside, through the notch at the bottom of the reader.
3.1.1. Installation
Remove the wall mount from the LDM 320W by unscrewing the four side screws.
Attach the plate to the wall via back-facing holes using four screws (not supplied).
