Page 2 of 18 MLXTM Mobile Platform Communication System User’s Manual Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Changes or modifications not expressly approved by Modular Mining Systems could void the user’s authority to operate this equipment. Page 3 of 18 MLXTM Mobile Platform Communication System User’s Manual MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS Use only antennas supplied by Modular Mining Systems or dealer. Antenna Minimum Safe Distance: 20 cm Antenna Gain: dBi referenced to a perfect isotropic radiator. The Federal Communications Commission has adopted a safety standard for human exposure to RF (Radio Frequency) energy which is below the OSHA (Occupational Safety and Health Act) limits. Antenna Mounting: The antenna supplied by Modular Mining Systems or dealer must not be mounted at a location such that during radio transmission, any person or persons can come closer than the above minimum safe distance to the antenna, i.e. 20cm. To comply with current FCC RF exposure limits, the antenna must be installed at or exceeding the minimum safe distance shown above, and in accordance with the requirements of Modular Mining Systems. Antenna substitution: Do not substitute any antenna for the one supplied or recommended by Modular Mining Systems. You may be exposing person or persons to harmful radio frequency radiation. You may contact Modular Mining Systems for further instructions. WARNING: Maintain a separation distance from the antenna to person(s) of at least 20cm. You, as the qualified end -user of this radio device must control the exposure conditions of bystanders to ensure the minimum separation distance (above) is maintained between the antenna and nearby persons for satisfying RF Exposure compliance. The operation of this transmitter must satisfy the requirements of Occupational / Controlled Exposure Environment, for work-related use. Transmit only when person(s) are a least the minimum distance from the properly installed, externally mounted antenna. Professional Installation: This device must be professionally installed. Page 4 of 18 MLXTM Mobile Platform Communication System User’s Manual About This Manual This manual contains a description of the MLXTM Mobile Platform’s Communication System designed by Modular Mining Systems (MMS). Its use is intended for MMS personnel and clients who may be responsible for the system’s operation. System Description The MLXTM Mobile Platform’s Communication System is based in two components: • MLXTM Mobile Hub • Bi-directional Amplifier and Cavity Filter • Omni-directional Antenna MLXTM Mobile Hub Internally the MLXTM Mobile Hub contains a radio that operates with the standard IEEE 802.11g in the ISM 2.412 to 2.484 GHz frequency band. The modulation schemes used are OFDM for data rates 6, 9, 12, 18, 24, 36, 48 and 54 Mbps, reverts to CCK for 5.5 and 11 Mbps and to DBPSK/DQPSK for 1 and 2 Mbps. The radio has two ports (Primary and Auxiliary) configured to operate in diversity antenna mode. The diversity antenna mode scans the SNR of each port until one is found to be above a predetermine threshold. Then the radio receives and transmits only for this port (antenna) until it falls below the SNR threshold and the scanning process is again initiated. In other words, the MLXTM Mobile Hub only receives and transmits for one antenna at time. Basic form of scanning diversity Bi-directional Amplifier The Bidirectional Amplifier is designed to be used for IEEE 802.11g standard, providing up to 1W of AGC compensated transmit power and giving low noise amplification in receive mode. It provides spectrally clean power amplification in transmit mode. Page 5 of 18 MLXTM Mobile Platform Communication System User’s Manual Bidirectional Amplifier Block Diagram Page 6 of 18 MLXTM Mobile Platform Communication System User’s Manual Omni Directional Antenna Antenna diversity is an option and not a requirement. If the omni is positioned such that it is the highest point on the vehicle, then multipath is not a problem and a single omni performs 98-99% as good a dual configuration. The disadvantage with omni antennas on many mine vehicles is that they are prone to being knocked off during normal mining operations. Neglecting losses between the amplifier and the antenna (some minimal cable run is unavoidable), the radiated output power from a 6dB antenna would be 36dBm (4Watts). However, actual output power will be slightly less due to unavoidable losses (cables, connectors, etc). Block Diagram Omni Directional Antenna Configuration Page 7 of 18 MLXTM Mobile Platform Communication System User’s Manual Tune Up Information No tuning procedure is required by the end user since the RF power that is put in the entry of the amplifier is controlled by firmware (driver) being this less than 20 dBm, limit that permits to the Automatic Gain Control operates correctly in the range 2-20 dBm to obtain 30dBm RF power output as maximum. Page 8 of 18 MLXTM Mobile Platform Communication System User’s Manual Wireless Network Configuration The Wireless Ethernet adapter will obtain its IP address from the DHCP service. Make sure that the MLXTM Mobile Hub is being covered by the desired RF Wireless Access Point signal. 1. Press Ctrl-Alt-Del to open the “Windows Task Manager” 2. Press Alt-F 3.

Type “ping 172.16.1.99” and press “Enter” to do pings to the central server. Note that the central server IP address could be different depending of each installation. Page 10 of 18 MLXTM Mobile Platform Communication System User’s Manual 6. If the ping is successful type “ewfmgr c: -commit” and press Enter. 7. Type “shutdown –r –t 0” and press Enter to shutdown the MLXTM Mobile Hub. 8. Turn ON the MLXTM Mobile Hub again. 9. Repeat steps 1, 2, 3 and 5. 10. If everything is successful, the MLXTM Mobile Hub has been configured correctly. If not, please send it to the MMS office to be repaired.
