ARCXtend manual, August 2003 ii FCC Requirements for Operation in the Unites States Radio Frequency Interference Warnings & Instructions 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 designed to provide reasonable protection against harmful interference in a residential installation. This equipment uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following methods: • Reorient or relocate the receiving antenna • Increase the separation between the equipment and the receiver • Connect the equipment into an electrical outlet on a circuit different from that which the radio receiver is connected • Consult the dealer or an experienced radio/TV technician for help Modifications made to the product, unless expressly approved by Arcwave, Inc. could void the user’s right to operate the equipment. RF Exposure CAUTION: To ensure compliance with FCC RF exposure requirements, the antenna used for this device must be installed to provide a separation distance of at least 20 cm from all persons and must not be located or operated in conjunction with any other antenna or radio tran…

Figure 3-10: Pole Mount with temporary pivot bracket detail. It is often convenient to temporarily mount a spare pair of brackets below where the Access Point will be placed. This serves as a pivot point, as well as stopping slippage during installation, as in Figure 3-10. While downtilt is normally not needed, the nuts on either side of the Access Point’s “ears” also serve to establish downtilt. The following Figures 3-11 & 3-12 show the measurement, and the difference in the top and bottom measurements creates the downtilt. ARCXtend manual, August 2003 3-16 Figure 3-11: Measuring bottom spacing. Figure 3-12: Measuring top spacing. ARCXtend manual, August 2003 3-17 3.8.1 Bracket Mount There is a wide range of hardware vendors and approaches to mounting a pipe on a utility pole. For example, Valmont or RFS Celwave (Figures 3-13 & 3-14) will mount on the common wooden utility pole and any pipe of the proper OD can be clamped to it. Arcwave makes a bracket with the pipe welded to the bracket, which is simpler and lighter than the general purpose mounting kits. This was shown in the previous photographs. The industry has many variations on utility pole materials, e.g., metal & cement, and there are many solutions to mounting a pipe on those poles. The Vertical-Mount Access Point mounts on the pipe. Figure 3-13: Valmont Chain-Mount Pipe-Mount Kit combination. ARCXtend manual, August 2003 3-18 Figure 3-14: RFS Celwave Pole Brackets. 3.9 Strand Mount The majority of Access Points are expected to be mounted on the wire strand that supports the coaxial cable system. The strand-mount kit is designed to support a Horizontal-Mount Access Point. There is an arm at each end of the Horizontal Access Point. The top of the arm is clamped to the strand, as in Figure 3-15. The top of the arm is designed to slip in between the strand and the coaxial cable, which is usually spiral wrapped to the strand. ARCXtend manual, August 2003 3-19 Figure 3-15: Strand-mounted Access Point. In high-wind installations, the Access Point can be stabilized by clamping the bottom of the arm to a second strand. ARCXtend manual, August 2003 3-20 Figure 3-16: Strand Mount bracket detail. Figure 3-16 shows the detail of the strand mount bracket. ARCXtend manual, August 2003 3-21 Figure 3-17: Strand-mounted Access Point with dual clamping. 3.10 Verify Service Area When the Access Point is installed, its coverage should be verified by a sampling of building locations. ARCXtend manual, August 2003 3-22 4 Command Line Interface The ARCXtend has a Command Line Interface (CLI) function. The commands will be used by a technician in preparing an Access Point for service and field installation. Some technicians like to “burn-in” a unit prior to field deployment, and this burn-in period is a practical time to also pre-configure a unit via CLI for the parameters used in the network. 4.1 Physical Interface The physical interface is a four-wire EIA/TIA-485, which is a buss interface. The EIA/TIA-485 interface parameter settings are: 9600 baud, 8 bit, 1 stop bit, no parity, no flow control, local echo OFF. NOTE: Most PCs will require an RS-232 to EIA-485 converter. 4.2 Command Line Characteristics All valid commands are automatically saved as soon as they are accepted. Saved commands are not changed by power cycling (ON/OFF). All valid commands are echoed by the Module being addressed, so a technician can visually verify that the correct action has been taken. Commands or parameter values that are not used by the Module are refused (no change in settings) and echoed with the message: “Invalid Command/Parameter”, or a similar response, and a list of the acceptable input options. The “invalid” message is followed by the login response. Commands and parameters are NOT case sensitive. Commands have no spaces. Characters are 8-bit ASCII visible characters. Backspace is the only permitted invisible ASCII character. Login addresses for the Modules inside the Access Point are: 1. 01 = AR250 DX Module 2. 02 = AR150 TX Module 3. 03 = AR105 RX Module Commands that are common to all three modules are: 4. Login 5. Help 6. Quit 7. Banner ARCXtend manual, August 2003 4-1 8. Title 9. Initialize The system response and output is slightly different for each module, as will be explained. From/to tap (RF + Vac) V Power Pickoff Power Supply TXRXDX DX AR250 RX AR105 Receive Module TX AR150 Transmit Module RX & TX Antennas AC RF Control RS485 > Figure 4-1: Block Diagram AX1255 Access Point. 4.3 TX Command Line Interface The commands unique to the TX Module are: 1. Downstream Air Frequency 2. Downstream Enable These will be explained here. 4.3.1 TX Login The LOG Login command is required to establish one-to-one communications with a particular Module. Because this is a bussed system, one and only one Module can be active at any one time. Prior to the complete Login command, no responses or echo backs will occur. Once logged into one Module, one-to-one communications can occur. It is only necessary to log into a Module once to establish communications. *LOG<nnmm>, where nn = mm = {01, 02, ... 7F} is the hexadecimal address of the Module within the ARCell Transceiver/Antenna unit and is entered twice, i.e., nn and mm are identical. ARCXtend manual, August 2003 4-2 Note that the Login command begins with an asterisk (*), and the Module’s address is repeated twice. Prior to Login, no Module is active, and no character echo back will be received on the PC. Example, to log into the Transmit Module (AR150): Type: *log0202 (all of which is hidden because it is not echoed) AR150TX [02] (this is what the Module sends to indicate successful login) The information above echoed by the addressed Module is: the Module type (AR150), the function (TX = Transmitter), and the hex address (02). The LOG command will automatically make any other active Module Quit (logout) if it was previously enabled. 4.3.2 TX Downstream Air Frequency The Downstream Air center Frequency is set within th…
