User manual

AW900m User’s Manual Thank you for your purchase of the AW900m Module. If you have any questions when configuring your AvaLAN module, please send us an email: support@avalanwireless.com Quick Setup for systems using the AW900m Module: 1. Attach an RPSMA 900MHz antenna to each module. 2. Plug in the AW900m module. 3. Connect an Ethernet cable from each AW900m to a network device. 4. Send Ethernet traffic. For troubleshooting see page 2. Each AW900m radio automatically selects the best radio channel, encrypts the Ethernet traffic and transports the data wirelessly to its mate. AW900m Ethernet RJ45 Power 9VDC AW900m EthernetRJ45 Power 9VDC 900 MHz Radio Ethernet Bridge Any Ethernet device can be connected to the AW900m. The AW900m functions in place of an Ethernet cable and provides a transparent wireless point to point Ethernet cable replacement. Cross-over cables are not necessary as the AW900m automatically senses the device (client or switch.
LED display: The AW900m has a 16 LED display to display the status of the device. LED Name Function Color 1 Power Unit has power and has successfully booted.

No Radio Link LED: The radio is looking for its matched partner. If both units are powered up and the Power LEDs are active they may be too far away to create the radio connection. Try other locations that may have a less obstructed path or try to reorient the antennas. Yagi type antennas get their best range when they are oriented to point directly at each other with the antenna elements oriented in the same plane (eg. vertically or horizontally) Radio LINK LED on but Link Quality Indicator is low: The units may be too far away to create a good radio connection. Try other locations that may have a less obstructed path or try to reorient the antennas. No Ethernet LINK LED: Check your network connections. Installing Multiple systems in close proximity: See the online installation tutorial and FAQ at www.avalanwireless.com Still not working? Temporarily use an Ethernet cable to see if the network is working over a wired connection. If an Ethernet cable does not work then the problem is with the network.

Advanced Settings: Automatic frequency selection mode (DIP switches – all OFF for automatic mode) The AW900m is designed to automatically select and continuously optimize the performance of its radio channel. The radio channel is monitored to ensure it is providing low error rates necessary for successful radio transmission. In the event that the error rate rises, the AW900m will autonomously change to a new channel. There are 12 non-overlapping channels. Manual frequency selection mode To restrict the operation of the AW900m to a subset of the 902-928 band, the user may activate a manual selection mode that allows the radio to automatically choose the best channel within a grouped subset of the 12 available channels. This is enabled by the 8 position DIP switch on the master unit. These settings allow the AW900m to operate on the optimal channel in one of three subsets, LOW 4, MID 4 or HIGH 4. The DIP switch setting are: Channels DIP Setting Frequency LOW 4 - 1,2,3 or 4 2 On / 3 Off 903-909 MHz MID 4 - 5,6,7 or 8 2 Off / 3 On 911-917 MHz HIGH 4 - 9,10,11 or 12 2 On / 3 On 919-925 MHz Or - the user may wish to select a specific channel. This can be done by setting DIP switches 5-8 as shown in the table below. [Turn DIP 2 Off / 3 Off] Channel DIP Setting Frequency 1 5 On / 6 Off / 7 Off / 8 Off 903 MHz 2 5 Off / 6 On / 7 Off / 8 Off 905 MHz 3 5 On / 6 On / 7 Off / 8 Off 907 MHz 4 5 Off / 6 Off / 7 On / 8 Off 909 MHz 5 5 On / 6 Off / 7 On / 8 Off 911 MHz 6 5 Off / 6 On / 7 On / 8 Off 913 MHz 7 5 On / 6 On / 7 On / 8 Off 915 MHz 8 5 Off / 6 Off / 7 Off / 8 On 917 MHz 9 5 On / 6 Off / 7 Off / 8 On 919 MHz 10 5 Off / 6 On / 7 Off / 8 On 921 MHz 11 5 On / 6 On / 7 Off / 8 On 923 MHz 12 5 Off / 6 Off / 7 On / 8 On 925 MHz Site survey mode (DIP switch 4 - default is OFF for normal operation) In this mode the AW900m can perform a site survey. With this mode activated the radios send and receive at 100% capacity by transceiving self-generated simulated data. The installer can monitor the Link Quality display to assess channel quality while optimizing antennae orientation. The installer can manually select each channel to evaluate performance and identify the best channels for operation. By identifying channels with poor performance it is possible to identify possible interferers and use “manual frequency selection mode” to avoid portions of the band or select a fixed operating frequency. Important note: Ethernet traffic does not get transported while the radios are in this mode.

FCC Notices Adherence to the following is required: IMPORTANT: The AW900m OEM RF Modules have been certified by the FCC for use with other products without any further certification (as per FCC section 2.1091). Changes or modifications not expressly approved by AvaLAN could void the user’s authority to operate the equipment. IMPORTANT: OEMs must test their final product to comply with unintentional radiators (FCC section 15.107 and 15.109) before declaring compliance of their final product to Part 15 of the FCC Rules. IMPORTANT: The AW900m OEM RF Modules have been certified for fixed base station and mobile applications. If modules will be used for portable applications, the device must undergo SAR testing.
FCC-Approved Antennas (900 MHz) Fixed Base Station and Mobile Applications AvaLAN Modules are pre-FCC approved for use in fixed base station and mobile applications. When the antenna is mounted at least 20 cm (8”) from nearby persons, the application is considered a mobile application. Portable Applications and SAR Testing When the antenna is mounted closer than 20 cm to nearby persons, then the application is considered “portable” and requires an additional test be performed on the final product. This test is called the Specific Absorption Rate (SAR) testing and measures the emissions from the module and how they affect the person. RF Exposure (This statement must be included as a CAUTION statement in OEM product manuals.) WARNING: This equipment is approved only for mobile and base station transmitting devices. Antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. To fulfill FCC Certification requirements: 1. Integrator must ensure required text [Figure 1] is clearly placed on the outside of the final product. 2. AW900m Module may be used only with Approved Antennas that have been tested with this module.

Certified Antennae Antenna Warning WARNING: This device has been tested with Reverse Polarity SMA connectors with the antennas listed in Table 1 Appendix A. When integrated into OEM products, fixed antennas require installation preventing end-users from replacing them with non-approved antennas. Antennas not listed in the tables must be tested to comply with FCC Section 15.203 (unique antenna connectors) and Section 15.247 (emissions). IC (Industry Canada) Certification Labeling requirements for Industry Canada are similar to those of the FCC. A clearly visible label on the outside of the final product enclosure must display the following text: Contains Model AW900 Radio, IC: 5303A-AW900M Integrator is responsible for its product to comply with IC ICES-003 & FCC Part 15, Sub. B - Unintentional Radiators. ICES-003 is the same as FCC Part 15 Sub. B and Industry Canada accepts FCC test report or CISPR 22 test report for compliance with ICES-003.
