Axiometric Gateway Guide MeshPlus™ Axiometric Gateway Users Guide Version 2007.09.01 Axiometric Gateway Guide MeshPlus™ Gateway 2 User's Guide 1. Overview This document explains the features and operation of the MeshPlus TM Gateway 2. The Gateway 2 serves three main functions:
Mesh controller – coordinates the wireless communication for thousands of remote MeshPlus TM devices. The Gateway 2 serves as a master timing source for all devices in a mesh.
Data collector – gathers telemetry data from the remote MeshPlus TM devices and stores it in up to 4GB of non- volatile flash memory storage.
Network bridge – transfers the telemetry data from the MeshPlus TM wireless mesh network to a TCP/IP network using Ethernet, 802.11b (WiFi), GPRS/EDGE (cellular), POTS Modem, or other network interfaces. Each function will be addressed in detail in the following chapters. 2. Installation The Gateway 2 is the heart of every MeshPlus TM wireless mesh telemetry network and is typically the first device deployed. The Gateway 2 is usually mounted outdoors either on a pole or structure using included hardware. a) Configuration Prior to mounting and installation, the network bridge interface should be configured and tested. The Gateway 2 is factory configured with one of three network bridge interfaces: Ethernet, WiFi, or Cellular. Consult the chapter for the selected network interface for details on configuration and testing. b) Mounting For maximum efficiency, the Gateway 2 should be mounted in a high location with an unobstructed view of as many mesh devices as possible. However, the Gateway will operate correctly as long as it is within wireless range of at least one mesh device. Gateway 2 Gateway 2 Pole Mount Axiometric Gateway Guide MeshPlus™ POE Injector The Gateway 2 requires an external AC (110-220VAC 50/60Hz) or DC (POE or Solar) power source and should be mounted in a location with convenient access to power. When using solar power, the solar panel should be angled towards the sun in the South to gather maximum energy. When using Power Over Ethernet (POE), the DC source voltage should be adjusted based on the length of the Ethernet cable to deliver approximately 12vdc to the Gateway 2. An un-interruptible power source (UPS) should be used with the POE DC power source at the injector. Based on the network bridge function selected (Ethernet, WiFi, POTS, or Cellular), the gateway should be mounted with clear access to the remote network. For example, a Gateway 2 with WiFi bridge option should be mounted with an unobstructed view of the WiFi access point it will communicate with; similarly, a Gateway 2 with Cellular bridge option should be mounted with an unobstructed view of the cell tower it will communicate with. c) Startup Once configured and mounted, the following steps should be followed to start Gateway 2 operation: 1. With external power disconnected remove the four bolts that secure the Gateway 2 front panel; carefully remove the panel and install a UM-1 lithium battery (Tadiran Pulses Plus recommended) in the battery clip on the right side of the gateway. Connect the battery connector to the Gateway 2 main board header JP3 observing the polarity of the header. The LEDs on the Gateway 2 Mesh Stamp should illuminate and begin blinking. Lithium backup battery Axiometric Gateway Guide MeshPlus™ The lithium battery does not supply any power to the Gateway in normal operation and has a typical service life of 10 years. When all other Gateway power sources are lost, the lithium battery can power the mesh controller and data collection functions of the Gateway 2 for over 6 months during an extended power outage ensuring that mesh operation and data collection continue without data loss. The lithium battery does not power the network bridge function. The lithium battery is a primary cell (it is not rechargeable) and should be replaced after an extended power outage (> 6 months total power outages) or when its typical service life has been reached (10 years). 2. If the Gateway 2 is equipped with the optional NiCd battery pack, fasten the pack to the inside of the front panel using the included 3M industrial hook and loop fasteners. Connect the battery pack to the Gateway 2 main board header JP4 observing the polarity of the header. The NiCd battery pack powers all Gateway 2 functions including the network bridge function for up to 48 hours during typical power outages allowing data collection and reporting (including the reporting of the power outage alarm) to continue during most power outages. The NiCd battery pack is rechargeable; during normal operation the NiCd pack does not supply power to the gateway; instead, when external AC or DC power is present, and a constant trickle charge is provided to charge the battery and maintain its maximum level. The NiCd battery pack has a service life of between 5 and 10 years and should be replaced after 5 years of operation. 3. Make sure the battery cables are secure inside the enclosure and will not interfere with the front panel mounting. Check the positioning of the rubber gasket then replace the front panel ensuring the battery cables will not be damaged and secure the panel using the four bolts. The bolts should be tightened carefully to compress the gasket and ensure a water-tight seal. 4. Attach the supplied external antennas. Only the supplied antennas may be used with this unit. Lightning arrestors are recommended for all antenna connections. Note: To comply with FCC RF exposure requirements, the device and the antenna for this device must be installed to ensure a minimum separation distance of 20 cm or more from a person's body. Other operating configurations should be avoided. NiCd Battery Pack Connector Axiometric Gateway Guide MeshPlus™ 5. Connect the external AC or DC power source to start normal Gateway operation and begin charging the optional NiCd battery pack if present. Ensure a good ground connection is provided for AC or DC power; a m…

Document 9684-MPE FCC ID: VE4-GW2C-AC RF Exposure Test Report Washington Laboratories, Ltd ??DATE?? Maximum Permissible Exposure Evaluation for Axiometric, LLC Gateway II FCC ID: VE4-GW2C-AC October 2007 Prepared by: Steven D. Koster, EMC Operations Manager WLL PROJECT #: 9684 This report may not be reproduced, except in full, without the prior written consent of Washington Laboratories, Ltd. RF Exposure Evaluation Document 9684-MPE FCC ID: VE4-GW2C-AC RF Exposure Test Report Washington Laboratories, Ltd ??DATE?? 1 Maximum Permissible Exposure Test Report for FCC ID: VE4-GW2C-AC 1.0 Introduction This report has been prepared on behalf of Axiometric, LLC Gateway II. Transmitter to show compliance with the RF exposure requirements as defined in FCC §1.1307. 1.1 Requirements Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These categories are fixed installation, mobile, and portable and are defined as follows: ƒ Fixed Installations: fixed location means that the device, including its antenna, is physically secured at a permanent location and is not able to be easily moved to another location. Additionally, distance to humans from the antenna is maintained to at least 2 meters. ƒ Mobile Devices: a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to be generally used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. Transmitters designed to be used by consumers or workers that can be easily re-located, such as a wireless modem operating in a laptop computer, are considered mobile devices if they meet the 20 centimeter separation requirement. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091. ƒ Portable Devices: a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable device requirements are found in Section 2.1093 of the FCC's Rules (47 CFR§2.1093). For this test report the Axiometric, LLC Gateway II was evaluated as a mobile device. Antenna: 5.5 dBi Whip antenna Evaluation distance: 20cm test distance. The FCC also categorizes the use of the device as based upon the user’s awareness and ability to exercise control over his or her exposure. The two categories defined are Occupational/ Document 9684-MPE FCC ID: VE4-GW2C-AC RF Exposure Test Report Washington Laboratories, Ltd ??DATE?? 2 Controlled Exposure and General Population/Uncontrolled Exposure. These two categories are defined as follows: ƒ Occupational/Controlled Exposure: In general, occupational/controlled exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who have been made fully aware of the potential for exposure and can exercise control over their exposure. This exposure category is also applicable when the exposure is of a transient nature due to incidental passage through a location where the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. Awareness of the potential for RF exposure in a workplace or similar environment can be provided through specific training as part of a RF safety program. If appropriate, warning signs and labels can also be used to establish such awareness by providing prominent information on the risk of potential exposure and instructions on methods to minimize such exposure risks. ƒ General Population/Uncontrolled Exposure: The general population / uncontrolled exposure limits are applicable to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general public would come under this category when exposure is not employment-related; for example, in the case of a wireless transmitter that exposes persons in its vicinity. Warning labels placed on low-power consumer devices such as cellular telephones are not considered sufficient to allow the device to be considered under the occupational/controlled category, and the general population/uncontrolled exposure limits apply to these devices. Since there are no warnings or training associated with this unit and it can be used by anyone, the Axiometric, LLC Gateway II is evaluated to the General Population/Uncontrolled Exposure limits. 1.2 Radio Frequency Radiation Exposure Evaluation The highest RF output power of the unit was measured is recorded. According to §1.1310 of the FCC rules, the power density limit for General Population/Uncontrolled Exposure is 1mW/cm 2 . The MPE shall be calculated at 20cm to show compliance with the power density limit. The following formula was used to calculate the Power Density: 2 4R PG S π = Document 9684-MPE FCC ID: VE4-GW2C-AC RF Exposure Test Report Washington Laboratories, Ltd ??DATE?? 3 Where: S = Power Density P = Output Power at the Antenna Terminals G = Gain of Transmit Antenna (linear gain-isotropic) R = Distance from Transmitting Antenna The calculation below determines that the device meets the 20cm minimum distance requirements. Table 1. Transmitter MPE Calculation Summary One Transmitter Frequency902MHz Limit0.601mW/cm^2 Distance (cm), R =20cm Power (dBm), P =22.77dBm TX Ant Gain (dBi), G =5.5dB Power Density: 0.13mW/cm^2 Separation<20 cm Minimum Distance:9.4 cm The calculation determines that the device meets the 20cm minimum distance requirements.
