The following operating modes are defined by the position of jumpers in the J16
connector (see § 3.1, page 12).
 Normal Operating Model.
 Test Mode.
2.3.1 Normal Operating Mode.
This is the normal operating mode of the reader.
In this mode, the reader functions as a slave of the PC.
 It receives commands from the PC.
 It searches for a dosimeter.
 It executes commands – reading or writing dosimeter parameters or information.
 It transmits a report to the PC.

LDM 210 - LDM 220 Description - Functionality
2.3.1.1 Retries
By default, the reader resends messages 10 times if the dosimeter fails to respond.
It is possible to disable the retries by relocating jumper SS4.
2.3.1.2 Reduced range
By default, the reader has a normal range of approximately 20 cm.
It is possible to reduce the range by relocating jumpers SS5 and SS8.
2.3.2 Test Mode.
It is a mode designed to verify proper functioning of the reader.
Refer to Corrective Maintenance in page 29.
2.3.3 The Digital Input/Output TOR
4 inputs and 4 outputs are managed by the reader by PC command.
These input/outputs are accessible on the HE10 male 2x7 pin 2.54 mm (0.1”0 spacing
connector).
They are protected against electrostatic discharge by protection diodes.
Inactive status (no exterior cable) of the inputs is a high level 3.3 V (pull up).
Active status is low-level 0 V.
Inactive status (by default) of the outputs is low 0 V.
Active output status is high-level 3.3 V.
These input/outputs can be used for example in an access control case:
 Access LED authorized or refused.
 Locking of access.
 System busy or available.
 Authorization request of passage, etc.

Installation and start-up LDM 210 - LDM 220
3. Installation and start-up
Keep the reader away from sources of electromagnetic fields (video
terminals, power supplies, PC, rotary machines, etc.)
Keep readers away from each other to prevent them from interfering with
one another (in case this is not possible, adjust the range of the readers
accordingly)
Keep readers at least 5 cm (2”) from metallic surfaces.
The installation and start-up of the reader consists in sequence:
 Install the software on the PC.
 Connect power to the reader (LDM 210 only).
 Connect the reader to the PC.
Note :
The LDM 210 can be equipped with an optional 2 alkaline AAA1.5 V batteries for operation without an
external power supply.
The LDM 220 is delivered for desk using (horizontally). It can be used in vertical fixing; a specific label is
delivered for this use.
