Preface Preface This manual covers basic configuration and installation of the M2400S Wireless Broadband System and applies to the following radio part numbers: M2400S-AP M2400S-SU 2.4 GHz Access Point 2.4 GHz Subscriber Unit FCC Information This device complies with Part 15 of FCC Rules and Regulations.
Introduction Section 1 Introduction Your Trango Broadband M2400S radio system provides a reliable and robust means to deliver broadband access to a wide geographic region through wireless Ethernet connectivity. This section will familiarize you with basic operational concepts, as well as an overview of the various components and hardware of the M2400S system.
Introduction Both APs and SUs feature a handy "site survey" tool to check for interference, as well as RSSI tools for optimizing antenna positioning. The M2400S also features variable receiver threshold, full power control, dual polarized antennas, and various link diagnostic tools. SmartPolling™ & Bandwidth Throttling One of the major advantages of the M2400S system is the ability of the AP to handle multiple SU connections and share the 5 Mbps data throughput efficiently.
Hardware Overview Section 2 Hardware Overview This section provides detail about each radio in the M2400S family. Each radio in the M2400S family includes a built-in, electronically switchable, dual-polarized antenna, as well as a reverse polarity SMA connector for the attachment of an external antenna. For ease of installation all units are designed for outdoor installation and powered by power-over-Ethernet (POE).
Getting Started The radio’s model number, FCC ID, MAC ID, and Serial # are located on the backside of the radio. Trango Broadband Wireless M24000S-AP Rev. A S/N: 00000XXXX MAC: 00 01 DE 00 02 F3 FCC ID: NCYM2400S Canada: XXXXXXXXXX This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are Figure 4: Back of Radio .600 6.
Getting Started • • • • • Connect a Cat-5 (straight through) Ethernet cable (we recommend shielded twisted pair) between the Radio port of the J-box and the RJ-45 connector on the radio. Note: this cable will carry power-overEthernet (PoE). NETWORK port connection is as follows: If connecting to a COMPUTER, use a Cross-Over Ethernet cable from the NETWORK port of the J-box to the computer’s Ethernet port. If connecting to a HUB, SWITCH, or ROUTER, use a Straight-Thru cable.
Getting Started Opmode To fully understand radio management for the M2400S system, it is important to be familiar with the concept of operation mode or “Opmode.” APs and SUs can be in one of two Opmodes (“ON” or “OFF”). When in Opmode “OFF”, the AP is not transmitting and is not attempting to associate with any SUs. Alternatively, when in Opmode “ON,” the radio is transmitting and attempting to become associated.
Getting Started In order to use the browser interface, simply connect the radio to a PC and type the radio’s IP address (default IP address=192.168.100.100) into the web browser (i.e. Microsoft Internet Explorer). This will bring up the Login page. NOTE: Login pages for AP and SU are similar. Browser Interface Login Page Type the password (default trango) and continue. This will bring up the radio’s system information page. Trango Broadband Wireless — User Manual M2400S Rev.
Getting Started Web Browser System Information Page ! Note: System Information screen for the Subscriber Unit is similar and is covered in detail later in this text. Primary Features and Pages of the 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 Link Control: This page shows which SUs are associated. This page also provides several tools for evaluating the quality of the wireless link. Command Console: From this page, the user can run any console command that is not interactive (i.e. ipconfig) or time sensitive (su linktest). For a complete list of console commands, type help or ? in the entry field. Logout: This link will end the current browser session with the radio.
Getting Started #> ! NOTE: The majority of the CLI commands will be covered throughout this text as well as in Appendix A − Command Set Reference. Troubleshooting If you cannot telnet into the radio or open a browser session, check cable connections, ensure proper use of crossover vs. straight-through cable, and ensure PC’s subnet is routable to radio’s IP address. If you still cannot access the radio’s management interfaces, consult the troubleshooting guide, which is available at www.trangobroadband.
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 CIR DOWN: Committed Information Rate from AP to SU. Minimum downstream rate (measured in Kbps) at which the AP will attempt to deliver bandwidth to that SU. Maximum setting is 5200. MIR UP: Maximum Information Rate from SU to AP. Maximum upstream rate (measured in Kbps) at which the SU will attempt to deliver bandwidth to the AP. Maximum setting is 5200. MIR DOWN: Maximum Information Rate from AP to SU.
Basic Configuration via Browser Interface 9. Enter the Device ID (MAC Address of the SU). 10. Save and Activate changes. ! ! Important! Always remember to Save and Activate changes, otherwise the SUDB will revert back to its previous state after a power cycle or reboot. Important! SUs using SU to SU communication must be on the same subnet.
Basic Configuration via Browser Interface 2. Set Base ID, or choose default base ID of 0000 (must match the SU). 3. Set AP ID (00-FF HEX). 4. Set IP, Subnet, and Gateway, or leave at default settings. Keep in mind if you change the IP Settings of the radio you will loose your HTTP session when you save and activate. 5. Choose Active Channel (1-8). 6. Choose Antenna Polarization (H or V) or choose E for an external antenna. 7. Ensure default Opmode is "ON." 8. Save and Activate Settings. 9.
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. SU Basic Setup: 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, or leave at default settings. Keep in mind if you change the IP Settings of the radio you will loose your HTTP session when you save and activate. 4.
Basic Configuration via Browser Interface LED Summary At this point it is useful to learn about the various LEDs that can be found on the bottom of the radio. These LEDs can assist the user in determining radio and link status. RSSI LEDs (YELLOW) - In all modes except "Survey," the unit's four yellow LEDs indicate the level of RF signal being received from a valid AP. ASSOCIATION LED (GREEN) Blinking once every second in Opmode "OFF" (AP and SU).
Basic Configuration via Browser Interface On this page the user can immediately see which SUs are currently associated. In the page shown, SU ID# 1 is associated, and SU ID# 17 is not. Consider "Power Off" status synonymous with "not associated." RF Link Loopback Test The RF Link Loopback Test is one of the built-in tools for evaluating the quality of the wireless link. Specify an SU ID and time in minutes to conduct the test. The test is prioritized, so it will take precedence over all other traffic.
Basic Configuration via Browser Interface SU Ranging Test This test reports the SUs distance from AP in miles, received signal strength for uplink and downlink, and SU TX Power. Use a link budget calculator to analyze results. Significant differences between calculated and actual values could indicate alignment or LOS issues! Advanced Setup Page The advanced set up page includes several important parameters including RF TX Power, RF RX Threshold, target RSSI from SU (AP only), and Channel Table.
Basic Configuration via Browser Interface Channel Table: Assigns channel numbers to actual frequencies of operation. Default settings allow the largest number of channels (8) within the band, while still maintaining a 10 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 the user.
Basic Configuration via Browser Interface Active Channel: The channel currently being used by the radio. 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 a smaller radius of operation use a higher threshold (-65 is higher than -70).
Basic Configuration via CLI Section 5 Basic Configuration via CLI This section covers how to utilize the radio’s CLI interface to establish a working wireless link. In this section, the most common settings using the CLI are discussed. Topics include: • Access Point Basic Settings • Subscriber Unit Database Settings • Subscriber Unit Basic Settings See Appendix A − Command Set Reference, for a complete listing of CLI commands.
Basic Configuration via CLI AP Parameter AP ID Opmode Default Opmode Opmode Start IP Subnet Gateway AP SYSTEM INFORMATION PARAMETERS AND RELATED COMMANDS Description Related CLI Command This parameter provides a set apid (00-FF in HEX) unique number for each AP. If Target AP is specified on SU, Example: #>set apid 33 the SU can only authenticate with the specified AP. The default AP ID is the last two bytes of the MAC address. Current Opmode of the radio.
Basic Configuration via CLI AP SYSTEM INFORMATION PARAMETERS AND RELATED COMMANDS AP Parameter Description Related CLI Command MIR Threshold (Kbps) User specified MIR Threshold. mirth [<0..3, Mbps>] To specify total throughput level that the AP will serve only Example: #>mirth 2 CIR (committed information rate) to associated SUs. When MIR Threshold is disabled, the AP will serve MIR for all its SUs.

Mounting Hardware Cabling and Grounding Considerations Grounding Example Proper mounting of the radio includes consideration for grounding. Please note that if the radio is attached to a metal pole that is earth-grounded, no other grounding is necessary. If the radio is not earth-grounded via the mounting bracket, you must attach a grounding wire to the grounding stud on the back of the radio as in the adjacent diagram.
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 Site Survey Example: #> survey 2 v Press [space] then [enter] to stop 2350 MHz peak -94 dBm avg -99 dBm 2355 MHz peak -94 dBm avg -99 dBm 2360 MHz peak -94 dBm avg -99 dBm 2365 MHz peak -94 dBm avg -99 dBm 2370 MHz peak -94 dBm avg -99 dBm 2375 MHz peak -94 dBm avg -99 dBm 2380 MHz peak -94 dBm avg -99 dBm 2385 MHz peak -94 dBm avg -99 dBm 2390 MHz peak -94 dBm avg -99 dBm 2395 MHz peak -94 dBm avg -99 dBm 2400 MHz peak -94 dBm avg -99 dBm 2405 MHz Ch 1 peak -91 dBm avg -92 dBm 2410 MHz peak -69
Deployment Once the SU is installed and aimed in the general direction of the AP it is time to perform an RSSI (relative signal strength indicator) test to determine the signal strength from the AP. Now you can precisely align the SU antenna for maximum signal strength. Although it is possible to rely upon the Subscriber Unit’s LEDs for alignment, more precise RSSI readings are available from the command rssi. In conjunction with the rssi command, it is also useful to perform the apsearch command.
Deployment SU Alignment Using LEDs The LED RSSI indicators on the bottom of the radio provide a handy alignment tool. If all four LEDs are lit, the unit is receiving –64 dBm or stronger. If no LEDs are lit, there is not sufficient signal strength to establish a wireless link. Lit LEDs Signal Strength 0 LED -86 dBm or weaker 1 LED -76 to -85 dBm 2 LED -69 to -75 dBm 3 LED -66 to -70 dBm 4 LED -65 dBm and stronger Note: RSSI tool (telnet or LEDs) will show all RF energy on a given freq. i.e.

Management ARQ with Selected Repeat and Multirate Feature The M2400S features ARQ, or “Automatic Repeat Request,” which provides the ability to correct for missing or erred packets of data by asking the sender to re-transmit the data. Both the AP and SU units implement a form of ARQ known as Selective Repeat. The units make a first attempt at transmitting a data frame using the 5.5 Mbps rate. Then, if a re-try is required, the 2nd attempt will be at 5.5 Mbps as well.
Management You can remotely change the SUs password for a single SU or all SUs in a sector using the syntax below: su password Example: su password all rw hello hello To remotely change the read write password on all SUs to “hello.” You can change the SUs IP, subnet, and gateway using the syntax below: su ipconfig Example: su ipconfig 7 192.168.10.10 255.255.255.0 192.168.10.
Management 2. 3. 4. 5. Tftp the file to the AP from your DOS prompt (example: tftp put mySUs.txt). From the AP telnet session run command sudb dload to load and activate the database. Run command sudb view to verify the database entries. Run the command save sudb to write the database to non-volatile memory.
