Chapter 1 Introduction Designed for 50 ohm coaxial transmission lines, the Bird Antenna & Cable Monitor is the solution for monitoring transmission antenna systems. Service providers and end users can rely on it to keep their critical sites up and running. Designed to detect antenna and cable faults that transmitter-internal VSWR monitors may not detect, it also provides accurate in-line power measurement functionality.
Component Description Figure 1 Antenna & Cable Monitor Outline 1 2 3 4 5 RF Input Forward Monitor Port Reflected Monitor Port RF Output Reset Switch 6 7 8 Operation/Test LED Alarm LED Ethernet Port 9 Power/Alarm Parallel Port 2 Connects to the amplifier or combiner Samples the forward travelling wave Samples the reflected wave Connects to the antenna or feeder Resets the alarm.
Chapter 2 Theory of Operation Alarm Response When an alarm is triggered, the Bird Antenna & Cable Monitor turns on the alarm LED and and de-asserts a TTL logic line (pulls low). In addition, depending on configuration settings, one Form C dry contact relay changes state (i.e. activates or de-acitvates) as a result of the VSWR alarm activating. A second Form C dry contact relay changes state as a result of either the low power or high power alarms activating.
No alarm is activated if the VSWR is less than the maximum, or if the VSWR alarm is disabled. If the VSWR is equal to or slightly greater than the maximum, additional measurements are accumulated to determine a trend. If reverse power is increasing, an alarm is triggered. If the reverse power is stable, measurements continue until a trend is established. An alarm will be triggered if the VSWR exceeds the maximum for more than thirty seconds.
Chapter 3 Installation This chapter provides information for preparing the Bird Antenna & Cable Monitor for use. Unpacking and Inspection 1. Carefully inspect the shipping container for signs of damage. 2. Note: If damage is noticed, do not unpack the unit. Immediately notify the shipping carrier and Bird Electronic Corporation. If the shipping container is not damaged, unpack the unit. 3. Note: Save the packing material in case the unit needs to be shipped again.
Connect the amplifier or combiner to the Monitor’s input. Connect the antenna or feeder to the output. WARNING Do not touch the center conductor of the power monitor ports while RF power is being applied. To monitor the RF waveform, connect the forward and reflected power monitor ports to an appropriate power sensor or meter. Note: If a power monitor port is not being used, terminate it with a 50 load.
Power/Alarm Connector Note: The power cable must be <50m in length. Connect the external power supply here. Pin numbers and descriptions are given in Figure 3. CAUTION The input voltage must be clean and stable. Ensure that the input voltage does not surge and does not contain spikes. Failure to comply may result in permanent damage to the instrument. CAUTION The maximum input voltage differential is 72 V for High Voltage models, 36 V for Medium Voltage models, and 18 V for Low Voltage Models.

Ethernet Connector Note: Max. Ethernet cable length must be <50m. The Ethernet connector carries data between the Antenna Monitor and a PC. When connecting to the ACMI using the Ethernet port, you use the WebTool software to setup the ACMI. You do not need to install the WebTool software because it is part of the ACMI firmware. In order to determine the IP address of the ACMI, the BMPE Finder utility will need to be installed.
Figure 5 Ethernet Connection Flowchart Note: The name you enter (at the left of the @ symbol) is also used in the ACMI Finder utility. If you use the email option to notify someone that an alarm has occurred, the name of this ACMI will help identify where the alarm came from.

Note: To use the features of the WebTool software, refer to Chapter 4 Operating Instructions on page 15.
WebTool Software Computer Requirements The WebTool software does not need to be installed because it is part of the ACMI firmware. The WebTool will run on any computer with Windows 98 or greater using a supported web browser with Java runtime installed. In order to locate the IP address of an ACMI, the BPME Finder Utility is used. This is a separate program that is installed on a host machine and is not part of the WebTool software.

Chapter 4 Operating Instructions WebTool Software The ACMI WebTool software is used to monitor the measurement outputs from the ACMI and to set and change alarm and network configurations. This software runs in a web browser (such as Microsoft’s Internet Explorer). To use the tool, open a web browser then in the address field, type the address of the BPM-E you wish to access. The software has five buttons at the left side that open the following screens: Main, Stats, Config, Admin, and Help.
Figure 6 ACMI WebTool Software, Main Screen Figure 7 Alarm Active Message Stats Screen The Stats screen (Figure 12 on page 20) can chart and display historical data stored in the ACMI memory. You can chart forward and reflected power readings and alarm conditions (low power, high power, and VSWR alarm). You can display the data in either a line graph or a bar chart. The ACMI keeps data for a 365 day period. You select the starting day (in the Begin field) and the number of days to view.
Data Log The BPME maintains a 365 day log (data log) of forward and reflected power readings and alarm conditions (low power, high power, and VSWR alarm). For each new day, the BPME will automatically take a power reading every minute and average it with the previous minute. This averaged value is temporarily stored every hour and then a new average is started.
Example - Comparing data from days 3-6 to days 203-206 on the same chart. You can view the days you've selected by scrolling the list to the right of the Add >> button under Day Selection. 2. 3. Note: The more days you view, the longer it will take to chart them. Include Alarm Data a. Check the Include Alarm Data check box. Note: This will retrieve alarm data for each selected day and generate a new alarm chart. The chart will be shown under the "Alarms" tab.
Get Data 1. 2. Click the Get Data button. Note: This will display the data for the current chart in a new window in a tab-delimited text format. Copy the text and paste it into a file on your computer or directly into a Microsoft Excel workbook. Note: In MS Windows, hold the Ctrl button and press A to select all the data, hold Ctrl and press C to copy, select your destination (e.g. Excel), and hold Ctrl and press V to paste. See the figure below for an example. Figure 10 Get Data Screen Day Detail 1.
Figure 12 Web Tool Stats Screen Config Screen The Config (Configure) screen has sets alarm configuration and analog output gain. The administrator of the WebTool can set an optional password requirement to control who can make changes to the Config screen (refer to Admin Screen for password control). Alarm Tab In the Alarms tab (Figure 13, page 22), you specify ACMI alarm settings. To return to the factory default alarm settings, click on the Factory Default button.
Checking the Alarm at Pwr Up box will cause the units alarm indicators and alarm relays to remain in an alarm condition from the time power is applied until the unit begins making measurements. At that time, the relays and indicators will return to their no-alarm condition until an event activates them.
Factory Defaults - Use the Factory Defaults button to clear all alarm settings and return the alarm configuration to factory default conditions (Latch Alarms and VSWR Alarm Enable checked, VSWR Trip Point =1.8). Figure 13 WebTool Config Screen, Alarms Admin Screen The Admin screen has four tabs, Network, Email Alerts, SNMP, and Passwords. After making changes in one or all of the tabs, click the Apply All Changes button to record your settings in memory.
Figure 14 WebTool Admin Screen, Network Setup Email Alerts Tab In the Email Alerts tab (Figure 15 on page 23), you can specify the following information: the SMTP server IP, the SMTP port, whether or not to use the email alerts, the email address of the ACMI, and the email addresses of two people to notify when an alarm occurs (optional). You can have the WebTool software contact two specified recipients via email if an alarm occurs.
SNMP Tab In the SNMP tab (Figure 16 on page 24), you can specify setup for the SNMP feature if you have chosen to use it. Contact your IT professional for assistance. You can obtain the latest MIB file from the Bird Technologies web site. Figure 16 WebTool Admin Screen, Set SNMP Email Address Password Tab In the Password tab (Figure 17 on page 25), you can set the administrator password and the optional configuration access password.
Figure 17 Web Tool Admin Screen, Passwords Help Screen While you are using the WebTool software, you can get on-line help about the screens and features by clicking on the Help button at the left side of the screen.
Push-to-Talk When enabled, the Push-to-Talk (PTT) feature monitors the PTT logic input on the DB-15 connector. When the PPT input is not asserted (low or open), the lowpower and VSWR alarms will not be monitored. When the PTT logic input is asserted (i.e. when the transmitter is keyed) the PTT delay timer will begin to countdown. During this PTT Delay, the low-power and VSWR alarms will continue not to be monitored.
Analog Output Gain This setting controls the sensitivity of the two analog outputs on the ACMI. The output level for the two channels are proportional to the measured power in the forward and reflected directions. The output range is 0 to 5.0 V with 10 bits of resolution. The gain settings allow the adjustment of the range at the cost of resolution. Example - At a gain of 1, the resolution is approximately 0.12% of full scale. At a gain of 8 it is approx 0.015% of full scale.
