2.1 Use and Functionality
-4-
The DMC 3000 Telemetry Module is the latest accessory for use with Mirion’s DMC 3000 electronic
dosimeter.
It enhances the DMC 3000 family of products by oering remote monitoring functions as well as
augmenting alarms through a series of bright LED indicators.
Additionally, the DMC 3000 Telemetry Module physically integrates into the dosimeter’s case, allowing for
continued ease of dosimeter operation and monitoring.
The DMC 3000 Telemetry Module uses WRM2 communication protocol. Hence, there is no need for
infrastructure upgrades. It integrates seamlessly with existing telemetry software.

General
2.2 Compatibility with Mirion Technologies Products
-5-
2.2.1 900 MHz and 2.4 GHz DM
2.2.2 WRM Protocol Compatible
The DMC 3000 Telemetry Module comes in both 900 (902−928) MHz and 2.4 GHzDM models, making it
compatible with existing base transceivers, repeaters, and other Mirion products.
The DMC 3000 Telemetry Module uses WRM2 communications protocol, and can be used with existing
telemetry software such as WinWRM2, Large Format Display, TeleView 2000 and TeleView 3000.

3.1.1 Dosimeter Preparation
■Dosimeter should be in Pause mode.
■DMCUser’s Parameter settings shall be congured as follows:
ӽFor “Accepted external module”select “All” or “Telemetry required”.
ӽFor “Enable external module”select “On”.
ӽFor “Allow external module” select “Yes”.
ӽFor “Enable external module”select “On”.

Functionality and Preparation for Use
-7-
■Ensure dosimeter is in Pause mode (i.e., not in Run or Sleep mode).
■Unscrew the two screws (1) with the screwdriver provided with your DMC 3000.
■Rotate and remove the battery cover (2).
■If not preinstalled, carefully insert 26-pin connector (3), ensuring side labeled “BATTERY SIDE” is inserted
closest to the battery.
■Engage the telemetry module front (i.e., LED) side rst (4) and rotate to close.
■Hand tighten with the tool provided at 0.25 to 0.35 Nm (2.2 to 3.1 in.Lb). Do not over torque.
■Insert battery into transmitter positive (+) side rst (see label on back of telemetry module).
■Ensure transmitter self tests (see Section 3.1.5) and dosimeter display’s transmitter icon activates
(see icon below). If errors arise, see Troubleshooting Guide in section 6.2.

Note: The transmitter will not work if the 26-pin connector is not installed.
The telemetry module must be connected for the rst time with the dosimeter in Pause mode to enable the proper
conguration recognition without risk of disruption of measurement operations. Once recognized a module may be
exchanged in Run mode, assuming there was some kind of module fault immediately prior to disconnection.

3.1.4 Handshaking
3.1.3 Detachment
■Ensure the dosimeter is in Pause mode.
■Detach the transmitter from the dosimeter.
■Recommended method for clearing“MOD DEF” alert indication from dosimeter display is to
perform the following:
ӽSelect “Detach Module”in the bottom of DMCUser’s window.
ӽAlternatively, remove the dosimeter’s battery and then put it immediately back into place.
■Replace the dosimeter’s battery cover.
■Ensure the dosimeter display’s transmitter icon deactivates.
The handshaking process is the sequence of data exchanges executed in order to check the information of
the connected module (type of module, status and conguration). The sequence is performed during the
initial connection process of the module or upon battery replacement.
This sequence is started by the dosimeter when it receives an acknowledgement from the module (on the
same signal used for the physical detection) that is ready for use.
For data integrity reasons this initial handshaking is prevented with dosimeter in Run mode in
order to preserve the main feature of the dosimeter: dose counting, alarming, and histogram/status
messages.

Functionality and Preparation for Use
-9-
In order to ensure the module preserves the longest transmit life, a battery self test and diagnostic LED
sequence is performed following battery installation:
■Upon insertion of new or unused battery, transmitter will perform a self-test with a green test
pattern on the right LED.
■If a used battery is inserted, the test pattern will illuminate a yellow pattern on the right LED.
3.1.5 Self Tests
Note: See also troubleshooting.
■Following the battery check the transmitter will also test alarm LEDs by illuminating both red LEDs.

4.1.1 Transmission
4.1.2 Alarms
The left green LED denotes proper reading of dosimeter data by the telemetry module.
The right green LED denotes transmission of
dosimeter data by the telemetry module.
The dosimeter display’s transmitter icon will also blink during data
transmission.
Data exchanges are the functional information transferred between the dosimeter and the telemetry
module in order to package and transmit dosimeter data. The DMC 3000 Telemetry Module has two
green LEDs. Under normal conditions, they shall both flash whenever the device transmits (i.e., every
2, 4, 8, 16, 32, or 64 seconds).
The telemetry module has two red LEDs that ash under alarm conditions.

4.1.3 Low/Dead Battery
■When the battery is dead (i.e., too weak to properly transmit), both yellow LEDs will flash in place
of the green LEDs.
Note: When the transmitter reaches its low battery state (yellow LED) the transmission frequency will double
its preset transmission interval (e.g., a 4 second transmission time to 8 second transmission time).
4.1.4 USB Connectivity
The blue LED will flash when the telemetry module is connected to a computer via the USB cable
and in communication with WRM Configuration Studio software.
Note: All functionality described in this manual is considered standard and default. However, rmware
upgrades and user congurations might aect settings. Contact your local Mirion representative with any
questions.
Although DMC/Telemetry Module has an ongoing communication, there is no data transmission
made when both LEDs flash yellow. However, alarm indication is still available.
The telemetry module has battery indicator LEDs that flash to indicate a weakened or dead battery.
■When the battery is weakened, the left yellow LED will flash in place of the green LED.

4.2 Battery Replacement
Telemetry Module Use
-12-
Note: If the transmitter’s battery is changed while the dosimeter is in Run mode, it can take up to ten minutes
for the new battery’s voltage to update in any telemetry readings. Alternatively, if after the battery change, the
dosimeter is put into Pause mode and again put back into Run mode, the transmitter should provide the new
voltage upon the next transmission.
Do not re-use previously used batteries. Mirion recommends new 1.5 VDC AAA Energizer alkaline or Duracell
alkaline batteries. Use of lithium or rechargeable batteries is strongly discouraged as they can negatively
impact expected battery life and functionality.
■Unscrew the telemetry module’s battery cover.
■Remove used battery.
■Insert new battery positive (+) side rst (see label on back of telemetry module).
■Reattach battery cover.
■Verify that a self-test is performed (see Section 3.1.5).
Battery Type:
Energizer or Duracell
Alkaline 1.5 V AAA LR03
A yellow and green ashing LED indicates the transmitter is still transmitting at a less than optimum
voltage level and a battery change should be performed within the next few hours (see Section 4.1.3).
The dosimeter will provide a warning upon detection of a transmitter dead battery threshold via a display
indication.

5- Configuration
5.1 Set Up & Configuration
-13-
The DMC 3000 Telemetry Module comes factory congured before use, with telemetry enabled. The
telemetry module is set to transmit every four (4) seconds.
Note:
The conguration software for the DMC 3000 Telemetry Module is intended for an appropriate experienced
user to modify selectable parameters outside factory default values.
If a telemetry module’s congurations have been changed while attached to a dosimeter in Run mode, the
dosimeter must be rst put into Pause mode for the changes to take eect.
Selectable Operating Features using the WRM Conguration Studio software:
■Firmware Upgrades
■Telemetry interval level - 2, 4, 8, 16, 32, or 64 seconds
■Enabling and disabling LED indicators
■Self-test mode settings
■Diagnostics
