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.
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.
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).

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.
