Note: Do not install an AA battery when powering the iPAM-Tx using an external
power supply.
2.1.2. Operation
•The iPAM-Tx is designed to transmit the TTL RS-232 data packet from the dosimeter
when the DMC-2000 or SOR/R is configured with transmission ON, 4800 BAUD,
Triggered Externally.
•The iPAM-Tx transmitter is compatible with all WRM2 900 MHz and 2.4 GHz DM systems.
•The unit is compatible with the entire DMC-2000 family dosimeters data formats (DMC-
2000S, X, XB, and SOR/R). The label on the iPAM-Tx located near the front cover center
should be removed when using the SOR/R, see Figure 1 in this section.
Note: The iPAM-Tx is configurable using WRM Configuration Studio software. Contact
Mirion Technologies for a software CD or downloadable link.
Note: For the DMC-2000XB an opening in the iPAM-Tx for the beta window can be
provided as a factory option.
2.1.3. Preparation for use:
Note: Ensure the electronic dosimeter is configured for telemetry and the
SPEAKER is enabled in DOSIMASS prior to use.
Step 1: Open the back case.
Step 2: Install a new AA battery, ensuring the correct polarity as indicated on the case.
The iPAM-Tx will vibrate, all the LED indicators will flash, and the buzzer will
sound briefly to verify all warnings/alarms are configured and working properly.
Step 3: The dosimeter must be installed with the display towards the top window face
down with the dosimeter clip removed. Once inserted, close the back cover,
ensuring the dosimeter is properly seated and aligned with the ISO connector.
Use the DMC-2000 clip to lock the case.
Note: The iPAM-Tx does not come with its own clip, but uses the DMC-2000’s clip to
lock closed. Users need to buy a separate DMC-2000 clip if using the iPAM-Tx with
SOR/R dosimeters.
Step 4: Turn the dosimeter ON. The iPAM-Tx will vibrate, all the LED indicators will
flash, and the buzzer will sound briefly to ensure all warnings/alarms are
configured and working properly.
Step 5: If the dosimeter alarms (e.g., dose or dose rate alarm), the enabled alarm
functions in the iPAM-Tx will be triggered (buzzer, vibrator, and red LED
indicators by factory default).

2.2.2. Operation
Step 1: The WRM2 Base Transceiver is a simple device that, after factory configuration,
requires no special configuration to operate. The single radio Base unit is pre-
configured to operate with same frequency transmitters (normally delivered with the
system). The network adapter must be set-up and configured for use on a user’s
facility local area network.
Step 2: The front panel of the base unit has the following components:
•Power Switch: Used to turn power ON and OFF.
•Power Connector: Used to connect external DC power to operate the base and to
charge the internal back-up batteries. A specially designed
switching regulator has been used to accept a large input
voltage range (9 to 18 VDC) and a smart charger for the NiMH
batteries. Optional POE (Power Over Ether network)
configuration.
•RS-232 Connector: Used to monitor base data received from remote units and to
access and configure the radios and network adaptor.
•RJ-45 Connector: Used to access the network for data broadcasting and network
adaptor configuration.
•Rotary Switch: Mode switch used to select specific base operations.

Step 3: As soon as the power is turned ON, any RF data received by the radio is converted to
RS-232 format and sent to the serial port (DB-9 connector if used) and the network
adapter (RJ-45 connector if used) simultaneously. This means that the base can be
connected to the network for the TeleView 2000 Software (Telecast Server) or other
similar program to read the TCP/IP transmission from the network adaptor and, at the
same time, a PC can be connected to the RS-232 port for local monitoring. Any RS-
232 data from the host computer will be transmitted to all remote units or MESH
Repeaters within range.
Step 4: Data to the serial port and network adapter is sent at by default at 19,200 BAUD,
Parity NONE, 8 Data Bits, and 1 Stop Bit. All data is ASCII formatted, permitting use of
any terminal program for inspection/troubleshooting.
Step 5: The data protocol of the output data is identical to the data going into the transmitter.
No modifications are made to the data stream from the source device except for baud
rate.
Step 6: The radios transmit data at 19,200 BAUD over the air and can be configured in a
variety of ways to optimize the system for throughput, data reliability, and range.
Contact Mirion Technologies for further information.
2.2.3. Radio and Network Adaptor Configuration
Step 1: The radios and network adaptor can be reconfigured using any terminal program,
such as Windows HyperTerminal, to change parameters such as Serial Protocol,
Network Address, Over-the-Air Radio Channel, etc. Refer to Section 2.2.3.3.3 and
Appendix 2.
Step 2: The rotary switch on the front panel can be used to select the following functions (as
depicted in Table 2 below):

2.2.3.1. Further description of the Communication Modes
Position 1: TX & RX NET, RX ONLY RS-232
•In this position, the base transceiver is configured to transmit and receive using
the Network Interface Adapter (NIA) and/or receive using only the RS-232 port (no
transmit capability via RS-232 port).
Note: The default LOCAL TCP PORT NUMBER for the network adapter is 4001.
Position 2: TX & RX RS-232, RX ONLY NET
•In this position, the base transceiver is configured to transmit and receive using
the RS-232 port, and/or receive using only the NIA (no transmit capability via the
NIA). The radio can also be configured in this mode position and requires a
specially designed software program.
CAUTION: The WRM2 radios are optimally configured for use with all WRM2
components and should not be modified. Contact Mirion Technologies for further
information.
Position 3: CONFIGURE NET OR RUN RADIO 2 RS-232
•This is the same as for Radio 1 if the base has the optional second radio installed.
•In Position 3, the RS-232 serial connector Rx and Tx lines are connected to the
network adaptor RS-232 serial lines. To configure the network adapter, Windows
HyperTerminal is the preferred method and is described in this section (Refer to
Appendix 2 for alternate programming software methods).
To program the network adapter perform the following steps:
Step 1: Power ON the WRM2 base unit.
Step 2: Set the Rotary Mode Selector to Position 3.
Step 3: Connect a straight RS-232 (9-pin Serial Cable) to the DB-9 connector of
the Base unit and PC.
