7 GENERAL DESCRIPTION The 429 series tower top amplifier system provides front panel Ethernet connectivity that allows access to a web-based interface for controlling and monitoring of amplifier currents, alarms, and attenuators. If you have not already done so, refer to Appendix A in your TTA s installation and operations manual for instructions on how to properly connect your computer to the TTA s front panel LAN port. Once you are properly connected to the TTA the web-based interface screen will appear in your web-browser s window. Figure 1 shows the interface screen as it appears after you first connect. The current Ethernet software version that is loaded into your TTA is displayed in the uppermost left corner while the model number of your system appears in the uppermost right corner. The rest of the display screen is divided into four functional areas including; Amplifier Status - provides continuously updated status information on the two tower top amplifiers. Amplifier Control - allows the user to interact with the two tower top amplifiers by selecting which is the active amp, terminating the amplifier inputs, and turning on/off the power supply feed to the amplifier. Attenuator Status - displays the current setting of both the TTA Net gain and distribution gain attenuators. Also allows the attenuator values to be either manually entered by the user or automatically calculated. Settings - the two uppermost registers are used to manually adjust attenuator values. The next two lowermost boxes are used when automatically calculating the TTA Net gain attenuator value. The last four lowermost registers use to store values of measured or estimated parameters.

8 Figure 2: Command Interface Button. Command Interface Button The lower left hand corner of the screen is the command interface button which allows changes you make on the web page interface screen to be downloaded to the TTA, see Figure 2. The command interface button acts as a trigger sending any changes you have made to the screen on to the TTA only after the button is pressed. To the right of the button are two status messages, one for the base connection and one for the tower connection. The command interface button is also used to display status information. The status messages include the following; DOWNLOAD COMMAND (black) - means there are currently no changes to transmit to the TTA. DOWNLOAD COMMAND (red) - means changes have been made and will be transmitted to the TTA once the button is pressed. After a download command is executed the button should turn black. NO CONNECTION - indicates that communications have been interrupted between your computer and the TTA. WAITING FOR UPDATE - This is a brief message that appears after you send a download command to the TTA. Once the new information is loaded into the TTA s memory this message will disappear. NON-FUNCTIONAL OVERIDE - This message appears whenever the TTA system is performing a task that interrupts the normal flow of RF signals through the system. An example would be if you asked the system to terminate the active amplifier. Refer to your TTA installation and operation manual under the section describing the TEST MODE for a further discussion of non-functional modes. BASE OVERRIDE - This message appears when commands are loaded into the TTA at the front panel that override commands being sent via the web page interface. Commands entered into the front panel have the priority. Amplifier Status This portion of the display shows the status of the two tower top amplifiers A and B, refer to Figure 3. The AMP A and AMP B column headings will be displayed as either Green, Yellow, or Red. Green These two column headings change color to indicate amplifier status Figure 3: Amplifier Status Area. TX RX Systems Inc. Manual /17/08 Page 2

9 indicates the amplifier is functioning normally, Yellow indicates it s in a warning state, and Red an alarm state. The rightmost column heading indicates which amplifier is currently active (amplifier A in the example shown in figure 3). In the six rows under the headings there are current values displayed for each amplifier including; CURRENT (ma) - this is the real-time current draw of each amplifier and the same value that is displayed on the front panel display screen. This value will update as required in real-time as long as the webpage interface is active. SHUTDOWN CURRENT (ma) - if the current draw of the associated amplifier reaches this shutdown point the supply current to the amplifier will be turned off. This protects the tower top box circuitry from excessive current draw. FAULT CURRENT UPPER/LOWER (ma) - These values are the alarm trip points for the respective amplifier. If the amplifier current draw reaches this point an alarm condition will be triggered. WARNING CURRENT UPPER/LOWER (ma) - These values are the warning trip points for the respective amplifier. If the amplifier current draw reaches this point a warning condition will be triggered. The values for the shutdown, fault, and warning trip points are calculated at the factory based on the normal current draw for your tower top amplifiers. The normal current draw may vary slightly between different tower top boxes because of slight variations in manufacturing tolerances. Amplifier Control This portion of the display allows the user to manipulate the operation of the tower top amplifiers. Figure 4 shows the amplifier control section of the screen. Remember to press the command interface button to transmit your selection to the TTA. Amplifier control choices include; ACTIVE - this selection allows the user to determine which of the two tower top amplifiers will be the active amp. The other amp will become inactive by default. TERMINATED - checking this box allows you to terminate the input of that particular amplifier. POWER SUPPLY ON - when checked the supply current to the amplifier is on and when unchecked it s off. Attenuator Status This area displays the current settings for both the TTA Net Gain attenuator and the Distribution gain attenuator. The TTA Net Gain attenuation can be derived as a manual input or it can be calculated automatically. To use the automatic mode click the circle next to the automatic label. Unclicking the circle will return you to the manual mode. Remember to press the command interface button to transmit any changes you make to the TTA. Figure 5 shows the Attenuator Status area of the screen. When automatic has been selected the message AUTO MODE will be shown on the MCU front panel display when you scroll down the menu choices to view the TTA Net Gain value. Refer to manual Installation and Operation manual for the 429 Series Tower Top Amplifier System. Any changes that are made manually to the attenuator value from the TTA front panel will not be allowed when the system is in the automatic mode. Settings The SETTINGS area of the interface screen allows attenuator settings, desired TTA Net Gain, and main transmission line loss values to be entered Figure 4: Amplifier Control. TX RX Systems Inc. Manual /17/08 Page 3

10 and saved. Figure 6 shows the SETTINGS area of the screen. The first value, TTA Net Gain, allows you to select the TTA Net Gain attenuation value. This box will be active whenever the attenuator status area is set to manual and will be inactive when the attenuator status area is set to automatic. In the automatic mode the TTA Net Gain attenuation value is computed automatically for you using the values you have entered for Desired TTA Net Gain and Main Transmission Line Loss as shown in figure 6. Remember to press the command interface button to transmit your selection to the TTA. The box for Test Transmission Line Loss provides a place to store the loss value of your test transmission line. The box for Distribution Transmission Loss provides a place to store the loss value of your distribution transmission line. The second value, Distribution Gain Attenuator allows you to program the distribution gain attenuation value into the TTA. Remember to press the command interface button to transmit any changes you make to the TTA. The next two values, Desired TTA Net Gain and Main Transmission Line Loss allow for automatic calculation of the TTA Net Gain attenuator. These boxes are active when the attenuator status area is set to automatic and they are inactive when attenuator status is set to manual. Remember to press the command interface button to transmit your selection to the TTA. The Static Sensitivity box provides a place to store your measured sensitivity value and the frequency you made the measurement at. Figure 6: Settings. The Dynamic Sensitivity Frequency box allows the selection of Low, Medium, or High. In order to check for sensitivity degradation, especially over wide frequency ranges in combined 700/800 Mhz systems, measurements at the lowest, midrange, and highest frequencies are recommended.
