15-00043 Revision 3 September 2005 1.0 Introduction The WRM2 telemetry system incorporates the features of multiple personnel devices into an integrated package. The WRM2 telemetry system components include: Compact Transmitter, Base Transceiver, Repeater and External Transceiver. The WRM2 Compact Transmitter, named “PAM-TRX”, (Personal Alarm Module Transmitter) is a multifunctioning transmitter for the DMC-2000 electronic dosimeter with enhanced alarm notifications and options for various frequencies.
15-00043 Revision 3 September 2005 2.0 Equipment Description & Operation 2.1 PAM-TRX (Personal Alarm Module Transmitter) 2.1.1 Features: • • • • • • High volume buzzer, 85 dBA at 2200 ± 500 Hz mounted on the top of the enclosure facing the user Two high intensity multicolor LED’s. One facing the user on top of the enclosure and one on the enclosure front to facilitate monitoring by other workers in the vicinity of the user.

15-00043 Revision 3 September 2005 The PAM-TRX is designed to transmit the TTL RS-232 data packet from the dosimeter when the DMC-2000 is configured with transmission ON, 4800 BAUD, Triggered. The unit is compatible with all the DMC family gamma dosimeters data formats (DMC2000S, X and SOR/R). Preparation for use: 2.1.2.1 To open the back case: remove the locking screw and slide off the battery cover. Remove the battery (if installed) and then slide off the case back. 2.1.2.

If changes need to be made to the slide switch, open the case on the rear of the unit. 2.1.3.1 With the help of Figure 1, locate the slide switch. 2.1.3.
15-00043 Revision 3 September 2005 The PAM-TRX has been designed to drive an external LED or high impedance Earphone that follows the alarm signal. The stereo alarm connector is compatible with MGPI external alarm devices like the EAM and the PEA-100 in the event that the user desires to use the PAM-TRX as a wireless area-monitoring device or further enhance the volume of the audio signal to over 100 dBA. NOTE: USE ONLY THE EARPHONE PROVIDED BY MGPI OR EQUIVALENT. STANDARD 8 OHM EARPHONES WILL NOT OPERATE.
15-00043 Revision 3 September 2005 2.1.7.5 Perform an operational test. Check the polarity of the batteries if the unit test. fails the 2.2 WRM2 Base Transceiver 2.2.1 Features: • • • • • • • • • • • Compact size self-contained transceiver unit. Compatible with all available frequencies. CE compliant with FHSS 2.4 GHz and 868 MHz radio installed. 902-928 MHz FHSS for North America Single or dual radio for streaming repeater applications. Simultaneous RS-232 AND TCP/IP outputs available.
15-00043 Revision 3 September 2005 Figure 3 below, depicts an image of the single radio WRM-2 Base Transceiver. Figure 3: WRM2 Base Transceiver 2.2.2 Operation The WRM-2 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).
15-00043 Revision 3 September 2005 Figure 4 below depicts the configuration of the front panel: Figure 4 – Front Panel Figure 5 below depicts the back panel of the base with one or two RPSMA connectors to connect the antennas. Figure 5 – Antenna Panel 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.
15-00043 Revision 3 September 2005 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. The radios transmit data at 19,200 BAUD over the air and they can be configured in a variety of ways to optimize the system for throughput, data reliability, and range. Contact MGPI for further information. 2.2.
-00043 Revision 3 September 2005 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 method) To program the network adapter: 1. 2. 3. 4. Power ON the WRM2 Base unit. Set the Rotary Mode Selector to Position 3.

The following screen is displayed: Figure 9: Network Configuration 10. Select 2, then press ENTER. The following menu will appear (Figure 10 below): Figure 10: Network Configuration The publication, translation or reproduction, either party or wholly, of this document are not allowed without our written consent.
15-00043 Revision 3 September 2005 11. Select 1 and press ENTER. - Change the IP Address (in accordance with the facility network scheme) and press ENTER. Perform changes, as appropriate, that meet specific network settings (as identified in Figure 10 above) for: - IP Address - Netmask - Gateway 12. Following completion of configuration, select “q” (Quit), and press ENTER.
15-00043 Revision 3 September 2005 If the base has been optionally configured with 2 radios, in this position Radio 1 serial data output is connected to the Radio-2 serial input in order for Radio-2 to transmit any RF data received by Radio-1 at once. This configuration is used for a streaming repeater mode. The network adaptor and RS-232 lines are connected to monitor Radio 1 data for local monitoring. Repeaters are factory set for use in an area where only one repeater is needed.
15-00043 Revision 3 September 2005 Eight (8) ‘AAA’ size NiMH batteries can power the WRM Base when external power fails for up to 4 hours. The base circuitry is configured to charge the batteries and provide warning when the battery voltage is too low to properly operate the base. The battery shelf life is expected to be 7 to 10 years. 2.2.5 Operational Test To test the base unit full functionality, perform the following steps: 2.2.5.1 2.2.5.2 2.2.5.3 2.2.6 Turn ON a PAM-TRX within range of the Base.
15-00043 Revision 3 September 2005 2.3 WRM-2 Repeater 2.3.1 • • • • • • • • Features: Compact and rugged unit used to repeat signals from and to remote units when the PAM-TRX units are outside the normal reception range of the base unit. Uses the same radio modules as the PAM-TRX and Base Transceiver. External DC power and optional built in battery back-up for 2 hours with alkaline 9 VDC Optional 9 volt NiMH rechargeable battery with built in trickle charger.
15-00043 Revision 3 September 2005 2.3.2 Operation The WRM-2 Repeater is a compact unit used to repeat signals from and to remote units when PAM-TRX units must operate outside the normal range of the base unit and there are no network connection points between the remotes and the base. Repeaters will reduce the amount of available over the air space when remote units transmit data within range of both the base and the repeater (the base will receive two data packets).
15-00043 Revision 3 September 2005 2.3.4 Operational Test The repeater can be tested using the same sequence as the base unit described in section 2.2.5. Turn the unit ON using the front panel power switch. Ensure the power LED (green) is illuminated. Install the correct antenna for the proper frequency. 2.3.5 Usage 2.3.5.
15-00043 Revision 3 September 2005 2.4 WRM2 EXT – External Transceiver 2.4.1 Features • Compact and rugged unit used to transmit signals from and to instruments fitted with RS232 output capabilities like the AMP family survey meters, RAM-R200, Ram Ion, ABPM 203M CAM, Telepole, ABPM monitors, and similar.
15-00043 Revision 3 September 2005 2.4.2 Operation The WRM-2 EXT is a compact unit used to transmit and/or receive serial data in TTL or standard RS-232 from HP instruments to a WRM-2 Base and Repeaters. Because of the open and flexible protocol used by the WRM-2 EXT, any device with RS-232 capability could be connected to the WRM-2 System like body temperature or heart rate sensors, GPS monitors, and chemical or biological detection systems.
15-00043 Revision 3 September 2005 2.4.3 Settings • • • • • Baud Rate - the EXT radio must be set for the same baud rate as the one used by the instrument. Available range is from 300 to 115,000 BPS (default 9600 Baud, N, 8, 1). Transmit mode – the EXT radio must be configured in cyclic sleep mode to strobe the data from the external device or in no sleep for devices that output data at regular intervals. Serial protocol – the EXT TXD and RXD data lines must be configured for the proper serial protocol.
15-00043 Revision 3 September 2005 2.4.4 Operational Test The EXT can be tested using the same sequence as the base unit described in section 2.2.5. Turn the unit ON using the front panel power switch. Make sure power LED (green) is lit. Install the correct antenna to ensure matching frequency. 2.4.
