2 Installation 2.1 Unpacking The FT-512 Trailblazer radio will arrive in one box approximately 19 x 15x 13 inches (47 x 37 x 32 cm). Small amounts of feed cable and/or power supplies may also be included in this box if ordered. ! Caution! Observe static precautions when wiring or handling circuit boards. There are nylon standoffs holding the antenna element to the reflector plate. These are fragile and can easily be over-tightened. They are set to a specific torque and if over-tightened may fail. 2.
2.3.2 Fresnel Zone, What is it, in plain English? In plotting terrain profiles for microwave frequencies, there are both direct and deflected waves that converge upon the receiving point. The direct path has a predictable behavior. Calculating losses from indirect or “deflected” signals however requires a different approach. To calculate the losses of the indirect signals, let us look at what occurs.
antennas so that the first Fresnel zone signal path is clear and the second is obstructed. 2.3.3 Radio Path Losses After confirming not only line of sight and adequate Fresnel zone clearance, it is then time to look at the Free Space Loss of the radio signal, RF cable losses, and antenna gains to determine how much is left over. The remaining signal is called the “Fade Margin”. Distance in miles 1.5 2.0 5.0 8.0 10.0 12.0 14.0 20.0 35.0 50.0 Distance in km 2.4 3.2 8.0 12.9 16.1 19.3 22.5 32.2 56.3 80.
These devices use analog radios which are usually fixed in frequency, 6 to 10 MHz bandwidth, low power with an ERP* of less then +10dBm. Cordless phones These devices are narrow band and fixed in frequency (during each use), a 1 to 2 MHz bandwidth, low power with an ERP of less then +10dBm. It is strongly recommended to avoid the use of 2.4GHz cordless phones in the vicinity of Trailblazer products.

3 Operation 3.1 Configuration with the Graphic User Interface 3.1.1 Overview The FT-512 GUI Optimizer software allows you to configure, test and monitor Trailblazer products easily through familiar setup screens. There are several screens that serve as input/output graphical representations of a more complicated Command Line script language. Operating parameters of the FT-512 boards are stored in Flash EEPROM onboard, simplifying manufacturing and field configuration. 3.1.
3.1.4 Running the FT-512 GUI CD in a computer Please have the COM cable connected before starting the GUI program. After a brief CWT splash screen with the GUI version number you will get a Select Port choice window. Figure 10: COM Port Selection Use this to select which COM port you have the SC cable connected to. Typically this is COM1 or COM2. Ignore the statement that “the configured serial port is not valid”.
The rotary switch position onboard the FT-512 is also shown here. Note at the bottom of the screen is a progress bar.

This is set to “Yes” if the system is designed for “always up” data use. If the system is used for POTS telephone service and should be off air when idle, then the switched position of “No” would apply. CDMA Code. We allow 4 non orthogonal codes to be used. This can be beneficial for reusing frequencies within a given area.
3.1.7 Choosing Channel Configurations The channel center frequencies are mapped to a number in the following charts. They can be configured and downloaded using the FT-512 GUI application running on a PC, or by using the manual selector switch as described in the following section.
Figure 14: Selecting the Operating Channel As a default we have selected 2.424, 2.448 and 2.460 GHz. 3.1.9 POTS Lines and Onboard V.35 Port Setup Figure 15: GUI - POTS lines and onboard V.35 port This screen allows one to implement a mixture of POTS and V.35 synchronous serial data services. At the bottom of the screen calculations show original, used and remaining bandwidth capacity. You can select a mix of services until the unused is zero.
4 Test & Maintenance 4.1 Diagnostics 4.1.1 Description of Diagnostic Functions The configuration GUI can be very useful at setup time. The disadvantage is that it requires a PC (laptop). 4.1.2 GUI Signal Strength and Packet Error Testing This screen is used for testing the radio path performance in the field. It shows in large letters the Current frequency, Signal strength and Packet errors.
Reset causes are broken down as such: Power – number of times the supply voltage failed. External – number of times the manual pushbutton has been depressed. Brownout – number of times the supply voltage went below the minimum of 10 volts but did not fail completely. Watchdog – number of times the watchdog initiated a reset. D4 - Link Connected?

5 Product Accessories / Options 5.1 External Antenna - Professional Installers Only Detached antennas, whether installed indoors or out, should be installed ONLY by experienced antenna installation professionals who are familiar with local building and safety codes and, wherever applicable, are licensed by the appropriate government regulatory authorities. Failure to do so may void the CWT product warranty and may expose the end user to legal and financial liabilities.
Upon opening the box one will find an N-female to N-male 36 inch long cable taped to the grid reflectors which are face down with corners padded. After removing the reflectors there will be a remaining box taped to the bottom. Inside this box will be the mounting bracket, clamp and hardware, extension tube, and dipole. 5.1.4 Product Overview The 24 dBi Parabolic Grid Antenna is welded galvanized steel with gray epoxy powder coat paint. Because of the design and color, it blends well with any background.
The total torque at the pole is the sum of the dipole and reflector torque: Ttotal = Tdp +Tref = Fdp x 9.5" + Fref x 5.5" = 39.9 + 94.6 = 134.5 in-lbs or 11.2 ft-lbs at the pole. Measurements show the bracket holding torque to be 26 ft-lbs with the bracket nut tightened to 30 in-lbs (hand tight on a wing nut), 50 ft-lbs with a nut torque of 55 inlbs and 70 ft-lbs with a nut torque of 75 in-lbs.
5.1.5 Installation The use of an external antenna with Model FT-512 Trailblazer Pro system mandates professionally trained personnel to ensure compliance with FCC rules and regulations. Specifically the installer must ensure that the EIRP of the transmitting antenna does not exceed the requirements of the Code of Federal Regulations, Title 47, paragraph 15.247. Calculating the EIRP of an External antenna The output of the FT-512 Trailblazer radio is calibrated at the factory to +16 dBm +/- 2dB.
Marketing and sales channels CWT DOES NOT sell the Trailblazer PRO direct to end users. i WLL Trailblazer PRO System will be sold only to CWT's Authorized Resellers. Those authorized resellers are technically trained by CWT's Engineers periodically and must follow the rules set by CWT. The Trailblazer PRO system is designed for Long Range (15-35 miles) applications and it involves a complicated mandatory site survey, roof top mast installation, high gain antennas, accurate antenna alignment, etc.
Final alignment is performed by connecting a standard telephone directly to the subscriber (FXS) wide and listening to the dial tone. As the antenna (device housing) is moved to the left the signal will degrade, the bit error LED will flash, and eventually the link will be lost. Noting where the antenna is aimed when the link is lost the antenna is then rotated to the right until the same dropout is experienced. The antenna is then located in a final position which is midway between these points.
