Preface Preface This manual covers basic configuration and installation of the Access5830 Wireless Broadband System and applies to the following radio part numbers: M900S-AP M900S-SU 900 MHz Access Point 900 MHz Subscriber Unit FCC Information This device complies with Part 15 of FCC Rules and Regulations.
Introduction Section 1 Introduction Your Trango Broadband M900S radio system provides a reliable and robust means to deliver broadband access and wireless Ethernet connectivity to a wide geographic region. This section will familiarize you with basic operational concepts as well as an overview of the hardware and the various components of the M900S system.
Introduction Each of the above parameters are set in the AP by the system administrator and cannot be controlled at the SU. These parameters will be covered in greater detail later in this text. When power is first applied to a properly installed SU, it will scan all available channels, searching for an AP with matching Base ID and MAC in its SU Database. The SU will then stop on that channel and respond to the AP using maximum RF power.
Hardware Overview Section 2 Hardware Overview This section provides detail about each radio in the M900S family. Each radio in the M900S family includes built-in, electronically switchable dual-polarized antennas as well as a reverse polarity SMA connector for the attachment of an external antenna. All units are designed for outdoor installation, powered by Power-over-Ethernet (POE) for ease of installation.

Getting Started AP and SU Switch 5 – In order to utilize the radio’s HTTP Browser interface, switch 5 (SW 5) must be “ON”. Default seting for SW 5 (from factory) is “ON”. SU Switch 6 - TCP/IP access direct to SU from SU side of network requires that switch 6 (SW 6) be “ON”. Default setting for SW 6 (from factory) is “ON”. If SW 6 is off, TCP/IP access to SU from SU the SU side of the network is possible only if SU’s opmode is OFF.
Getting Started Figure 3-3 Web Browser System Information Page Figure 2-3 shows system information for an Access Point. Basic system information for a subscriber unit is similar and is covered in detail later in this text. The following describes the primary features and pages of the HTTP Browser interface: Navigation Column: Each page features a navigation column which runs along the left-hand side of the page. The model number of the radio is listed at the top of the navigation column.
Getting Started Logout: This link will end the current HTTP session with the radio. Help: The Browser Interface features useful Help pages which explain all listed parameters. To access the help pages click on the Help link. For a complete description on use of the Browser Interface, see Appendix A. Command Line Interface Although most radio functions can be managed via the browser interface, the command line interface (CLI) does provide slightly more functionality. The CLI can be accessed through Telnet.
Basic Configuration via Browser Interface Section 4 Basic Configuration via Browser Interface This section describes a few more basic concepts and how to establish a basic wireless link between AP and SU, using the Browser (HTTP) Interface . This section is written to address only the most basic steps in establishing a link in the lab, or a bench-top environment.
Basic Configuration via Browser Interface . To set up an SU in the SU Database, complete the following steps: 1. Connect to the AP (see Getting Started) and open the Subscriber Database page. 2. Enter SU ID 3. Select: either PRIORITY or REGULAR. 4. If SU will be part of an SU to SU group, enter the SU to SU group number. 5. CIR up: (SU to AP Committed Information Rate) – minimum upstream bandwidth for the SU in Kbps. 6.
Basic Configuration via Browser Interface Configure Other Basic AP Parameters In addition to setting up the SU in the SU Database, the following settings from the AP’s Configuration page must be set (or left at default). Base ID: Four character, alphanumeric, user definable base station ID. Input of BASEID shall be in the format of xxxx. Where x is any character from the set : { 0..9; a..z; A..Z; '!@#$%^&*()_+[]\<>,./?' } .
Basic Configuration via Browser Interface 2. Set Base ID (Must match the SU) 3. Set AP ID (used to identify the AP, not essential to establishing a link) 4. Set IP, Subnet, and Gateway (Not essential for a link) 5. Set Default Opmode to "ON" 6. Set Active Channel 7. Set Antenna Polarization (H or V) or choose E for external antenna 8. Save and Activate Settings 9. Reboot System At this point the AP will begin actively searching for any SU in its SU database.
Basic Configuration via Browser Interface Configure Basic SU Parameters In order to establish a working link, the Base ID in the SU must match the Base ID of the AP To set up the SU, complete the following steps: 1. Connect to the SU (see Getting Started) and open the Configuration page. 2. Set Base ID (Must match the AP) 3. Set IP, Subnet, and Gateway (Not essential for a link) 4. Set Default Opmode to "ON" 5. Save and Activate Settings 6.
Basic Configuration via Browser Interface b) ACT LED Red: Link and Activity. Illuminated when a link is established. Will blink when link activity is detected. c) RSSI LEDs (4) In all modes except “Survey”, the unit’s four yellow LEDs shall indicates the level of RF signal being received from a valid AP.
Basic Configuration via Browser Interface SU Ranging / RSSI Test For specified SU reports the distance from AP in miles, SU Tx Power, SU temperature, and the received signal strength for uplink and downlink. Use a link budget calculator to analyze results. Advanced Setup Page The advanced set up page includes several important parameters including RF TX Power, target RSSI from SU (AP only). This screen also includes the radio’s channel table which can be configured by the user.
Basic Configuration via Browser Interface Channel Table: Assigns channel numbers to actual frequencies of operation. Default settings allow the largest number of channels (4) within the band, while still maintaining 6 MHz channel spacing. Other Key Parameters This section describes the remainder of the parameters listed on the System Information page. Most of these parameters are the same for both APs and SUs. Hardware Version: Hardware version is factory-set and can not be changed by user.
Basic Configuration via Browser Interface RFRx Threshold: Sets the receive threshold of the radio. The radio will not process signals received below this level, so it is very useful for interference mitigation. For smaller radius of operation use a higher threshold (-65 is higher than -70). Broadcast Packet: This software switch (0) enables/disables the blocking of Ethernet control packet except ICMP and ARP to reduce the amount of unnecessary overhead introduced to the wireless link.
Basic Configuration via CLI Section 5 Basic Configuration via CLI It is important for users to be familiar with the CLI interface as well as the Browser Interface. This section covers how to utilize the radio’s CLI interface to establish a working wireless link. Much of the information presented here is similar to the information presented in Section 4. In this section, the most common settings are discussed using the CLI.

Mounting Hardware Figure 6-3 Articulation for M900S with Mono Pod Mount (not supplied) Standard Mounting Alternative Mounting Cabling and Grounding Considerations Figure 6-4 Grounding Example Proper mounting of the radio includes consideration for grounding. Please note that if the radio is attached to a metal pole which is earth-grounded, no other grounding is necessary.
Mounting Hardware ? Note: Access to the radio RJ-45 Port and LED status lights are purposely located at the bottom of the radio to minimize the risk of water intrusion. Do not mount the radio upside down. ? Note: The J-Box is not a weatherized device and must be located either indoors or in a weather-protected cabinet. Shielded twisted pair Cat-5 cable is recommended for all installations. The shield within the Cat-5 cable does not need to be grounded if the radio itself is grounded.
Deployment Section 7 Deployment Once you are familiar with the basic operation of the radios you are ready for deployment in the field. The deployment process consists of the following steps: ?? Site Selection ?? Site Survey ?? Channel Planning ?? SU Antenna Alignment ?? Link Management Commands Site Selection Proper site selection for your AP will help ensure a successful deployment.
Deployment Freq Freq Freq Freq Freq Freq Freq Freq Freq Freq Freq Freq Freq Freq 902 904 906 908 910 912 914 916 918 920 922 924 926 928 MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz Ch 1 Ch 2 Ch 3 Ch 4 peak peak peak peak peak peak peak peak peak peak peak peak peak peak -73 -83 -90 -82 -84 -83 -90 -83 -90 -83 -83 -51 -60 –55 dBm dBm dBm dBm dBm dBm dBm dBm dBm dBm dBm dBm dBm dBm max max max max max max max max max max max max max max avg avg avg avg avg avg avg avg avg avg avg avg a
Deployment Step 2 The telnet session screen will begin a continuous readout of the received signal strength. As you read the RSSI reading, move the antenna in the horizontal and vertical planes until the maximum RSSI reading is achieved. For short links you can expect an RSSI of –60 dBm or better. For longer links and RSSI of –80 dBm is acceptable. Any RSSI of less than –85 dBm may be too weak for the radios to reliably associate and pass data.
Deployment In establishing and diagnosing the quality of the link between AP and SU(s), there are a few commands which are especially useful. All of these commands are performed at the AP. A summary of these commands follows: su Displays the status of all SUs in the AP’s database. SUs in the SU database will appear by SU ID, classified into one of the following status categories: Associated, Associating, and OFF. su live Displays a list of SU’s that are currently associating with the AP (by SU ID).
Deployment rssi This command can only be executed on the SU while in Opmode "SU" #> rssi [ [ [ [ [ [ 1] 2] 3] 4] 5] 6] peak peak peak peak peak peak -44 -44 -44 -44 -44 -44 dBm dBm dBm dBm dBm dBm avg avg avg avg avg avg -45 -45 -45 -45 -44 -50 dBm dBm dBm dBm dBm dBm **** **** **** **** **** **** linktest This command checks the integrity of the wireless link from the standpoint of performance. AP will send 500 large packets to the SU and the SU will return what it receives to the AP.

For thorough results it is recommended you run the command repeatedly for at least 1 minute or more to determine if packets are passing without error consistently over time.
Management Section 8 Management In this section the following topics will be discussed: ?? SU Management from AP ?? TCP/IP SU Management ?? Security ?? SNMP SU Management from AP Network management can be performed by the following methods ?? HTTP Interface ?? CLI See Appendix on Command Set Reference ?? SNMP Manager Discussed in this section, below The AP provides functionality and several commands which permit the management of associated SUs.
Management Loading Multiple SUs into SUDB using DLOAD Command To load a full database of SU entries into the AP database, you need to create a subscriber database in ASCII text file format. As shown below, each row represents all information for one SU. Each column is an information field, which includes: SU ID, SU to SU group, service level, CIR, MIR, and MAC address.
Management AP Bandwidth Monitoring ?? aptrafficEthRxAvgThroughputLog – Average payload data throughput (in Kbits/sec) received on the Ethernet port over the period of 1 minute. ?? aptrafficEthTxAvgThroughputLog – Average payload data throughput (in Kbits/sec) transmitted on the Ethernet port over a period of 1 minute. ?? aptrafficRfRxAvgThroughputLog – Average payload data throughput (in Kbits/sec) received on the RF link over a period of 1 minute.
