Safety Precautions
The following are general safety precautions that are not necessarily related to
any specific part or procedure, and do not necessarily appear elsewhere in this
publication. These precautions must be thoroughly understood and apply to all
phases of operation and maintenance.
WARNING
Keep Away From Live Circuits
Oper
ating Personnel must at all times observe general safety precautions. Do
not replace components or make adjustments to the inside of the test
equipment with the high voltage supply turned on. To avoid casualties,
always remove power.
WARNING
Shock Hazard
Do not attempt to remove the RF transmission line while RF power is present.
WARNING
Do Not Service Or Adjust Alone
Under no circumstances should any person reach into an enclosure for the
purpose of service or adjustment of equipment except in the presence of
someone who is capable of rendering aid.
WARNING
Safety Earth Ground
An uniterruptible earth safety ground must be supplied from the main power
source to test instruments. Grounding one conductor of a two conductor
power cable is not sufficient protection. Serious injury or death can occur if
this grounding is not properly supplied.
WARNING
Resuscitation
Personnel working with or near high voltages should be familiar with modern
methods of resuscitation.
WARNING
Remove Power
Observe general safety precautions. Do not open the instrument with the
power on.

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.
Features
Measures forward and reflected power as well as VSWR and Return Loss.
Measures true average power of pulses with high peak-to-average
ratios - works with any modulation.
When monitoring transmitter output power, alarms available for low
or high power.
Accurately monitors antenna and cable system VSWR. Alarm triggered
if antenna or cable fails.
Integral coupler measures small changes in VSWR through high feeder
and interface losses.
Note: High directivity maximizes measurement accuracy.
Sampling ports allow signal measurements without requiring system
downtime.
Excellent passive intermod allows the unit to be inserted into multi-
channel systems with a single Tx/Rx antenna with no desensing or deg-
radation of receiver performance.
Can be rack mounted at the output of transmitter combiner or linear
power amplifier.
Setup and operation via built-in PCTool software.

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. Refer to the Power/Alarm Connector pins for proper
connection and Alarm configuration for set-up.
The LED activates the TTL logic line de-asserts as a result any of the three alarm
conditions (VSWR, low or high power).
If power to the unit is lost, both relays default to their de-energized condition.
The PCTool software can configure whether the relays energize or de-energize
during initialization or in response to an alarm when the unit is operating. Refer
to the section on Alarms for instructions on setting alarm response behavior.
Alarm Reset
Alarms can be reset locally with the reset switch.
Alarms are reset when the reset pin on the Power/Alarm port is acti-
vated by a TTL compatible logic low signal (0 to 0.8 VDC).
The PCTool can reset the unit through the Ethernet port by sending a
“Reset Alarm” command.
Reset events clear all three alarms (VSWR, High Power, Low Power)
and reset both relays.
Alarm Latching
The alarm defaults to latching operation. In this mode, the alarm will stay active
until reset. In non-latching mode, the VSWR alarm will reset automatically about
forty seconds after the trigger condition is corrected, power alarms will reset in
about one-and-half seconds after the power condition is corrected.
VSWR Alarm
The ACM continuously monitors forward and reflected power. From the power
measurements, the VSWR is calculated and compared to the allowed maximum
(default of 1.5 to 1). Based on the results of the comparison, possible actions
include:
3
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.
If the VSWR is much greater than the maximum then an alarm condi-
tion is triggered immediately.
Alarm on Zero Power
When the forward power is very small (< 2.5% of full scale), the measured VSWR
becomes large due to the noise floor of the sensor. Under these conditions, the
VSWR level is meaningless. When the zero power alarm is disabled, the VSWR will
not be monitored at these low powers.
High Power Alarm
When the high power alarm is enabled, the forward power is continuously monitored. The alarm trigger is a percentage of the Monitor’s full scale power, from 0 –
125%. If the forward power is greater than the trigger level, an alarm is triggered.
Low Power Alarm
When the low power alarm is enabled, the forward power is continuously monitored. The alarm trigger is a percentage of the Monitor’s full scale power, from
0 – 125%. If the forward power is less than the trigger level, an alarm is triggered.
Push-to-Talk
The low power alarm and the VSWR alarm can falsely trigger when the transmitter is not keyed. The Push-to-Talk feature disables alarm checking for a predetermined period after the Push-to-Talk logic line is asserted. In order to prevent false
alarms while monitoring for low power and high VSWR, the Push-to-Talk feature
must be enabled.

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.
Note: You must have Java runtime installed before you can use the
WebTool software.
Network connections require specific address and protocol information. Have a
qualified IT or network professional perform the ACMI ethernet setup. Failure to
comply may result in loss of network communication or the inability to
communicate with the ACMI.
The setup in this section should be performed only by a person who thoroughly
understands IP and network setup protocols.
Note: If you are connecting to a network, before you begin, do the
following:
CAUTION
Contact your IT professional to get the subnet mask values for
your network and to determine whether or not your network
has a DHCP server.
Inform your network administrator that the ACMI will use port
10001. The network administrator might need to open this
port before you can set up the ACMI.
1. Install the Java runtime environment.
Note: Perform this step if it is not already done.
Note: To use the WebTool software, your PC must have the Java run-
time environment (java virtual machine v1.4.2 or later) installed prior to
connecting the ACMI to an ethernet device. If you do not have the runtime environment, you can download it from the web at www.java.com
or from the Bird Technology web site (www.bird-electronic.com). For
information about downloading the Java 2 Runtime Environment, refer
to the readme.txt file that was provided with your unit.
Dangerous RF voltage. Do not connect or apply an RF signal to the ACMI during
WARNING
equipment setup. Failure to comply may result in severe burns, loss of use of
limbs, or death.
WARNING
Do not connect RF power to the unit.
2. Apply operating power to the ACMI.
3. Follow the ethernet setup flowchart (Figure 5, page 10) to complete the
installation.

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.
To install and run the program, your computer system must meet or exceed the
requirements listed below:
486 or better CPU (66 MHz or better recommended)
1 MB of free memory
Hard Disk Drive
CD-ROM Drive
Note: Follow the instructions on the CD provided to install the software.
Web browser that supports Java Virtual Machine v1.4.2 or later such as
Microsoft Internet Explorer or Google Chrome Browser

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. You can
access information about the WebTool software by click on the Help button.
Main Screen
The Main screen is the default screen you see when you open the WebTool software (Figure 6, page 16). The Main screen identifies the ACMI at the top of the
window. The center of the screen displays measurement data that is being
received from the ACMI. You can set the refresh rate from 1 second to 60 seconds (how frequently the software updates the data from the ACMI). At the bottom of the window, the status bar displays various information about the
software and uses three alert colors, red - a fatal error (cannot establish connection, connection lost), yellow - a warning (cannot complete a user request, user
does not have access permission), gray - normal operation.
For more information about the Main screen features, refer to the help section
in the software (click on the Help button).
The alarm condition area (Figure 7, page 16) will display three conditions
No alarm (green text) - no alarm condition exists
Latched (red text) - an alarm condition did occur but its cause has been
fixed or the cause no longer exists.
Alarm (red text) - an alarm condition that has occurred and has not
gone away or been reset is identified by text (VSWR, High Pwr, Low
Pwr, or any combination of these if more than one alarm exists).
You can reset the alarm at the ACMI by pressing the reset button or by clicking
on the Reset Alarm button on the Web Tool Main screen. If the cause of the
alarm is still present, the message cannot be reset.
15

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. Day 0 is today, day 1 is yesterday,
and so on to day 364. Click the Add >> button to add the days to the list to view.
When you click the Chart It button, the WebTool retrieves the data and generates a new chart. Click the Clear button to clear your day selection.
The Stats View is not password protected. It is used to retrieve and plot historical data stored on the BPME. You can use the controls provided on this view to
generate charts and save the data for your records.
16
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. If an alarm occurred over
the course of an hour, then a value of '1' is logged for the specific condition that
triggered the alarm: low power, high power, and/or VSWR. At the end of a 24
hour period, the hourly power reading data is averaged and the percentage of
time that a specific alarm was on is written to non-volatile storage. Each individual hour’s data (both powers and alarms) is also written to non-volatile storage
at the end of the day. If the power is lost, you will loose only historical data
obtained for the current day after the log started and before the power went
out. All other data will remain intact.
Figure 8 Data Log
Day Selection
The steps to create and display information from the data log are: select the
days to view, choose to include or exclude alarm data, select chart type, chart
the data.
1. Select Days
a. Decide which days to view.
Note: Day 0 is today, day 1 is yesterday, and so on up to day 364.
b. Enter the day number of the log you wish to view in the Begin field
under Day Selection.

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.
Note: The more days you view, the longer it will take to chart them.
2. 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. See the figure below for an example of an alarms bar chart.
3. Choose Chart Type
a. Select the chart type: Line or Bar.
Note: A line chart will plot the data as a simple connected line graph
with data values on the y-axis and the time units (days or hours) on the
x-axis. The line chart has no day limit and can also be used to plot
hourly data.
Note: A bar chart will plot the data as vertical bars - one for each day
- with the days on the x-axis and the data values on the y-axis. You can
use the bar chart to plot up to only 12 days at once.
Note: Hourly data is logged with hour 0 as the first hour of the day
and hour 23 as the last hour of the day.
4. Chart the Selection
a. Click the Chart It button to retrieve the data and generate a new
chart.
b. Click Clear to clear your day selections.
Note: Once the chart has been displayed you can browse the various
graphs for each power scale and alarms by clicking on the appropriate
tab at the top of the chart. Each chart is plotted in a similar fashion from the least-recent to the most-recent data value aquired - when
reading from left to right along the x-axis.

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.
After you have set the alarm preferences, click the Apply Changes button to
record your settings in memory.
You can select or deselect the following alarm conditions:
Latch Alarms - Sets whether the alarm will reset automatically in the absence
of an alarm condition. When this checkbox is unchecked, if an alarm trigger is
corrected, the VSWR alarm will reset after a forty-five second delay and the
power alarms after a one and a half second delay. When the box is checked, the
alarms must be manually reset.
Alarm at Power (Pwr) Up - At power up, before the instrument is ready to
take measurements, the unit performs initialization tasks. During this period,
the units alarm indicators (LED & TTL output) will activate for ~2ms and the
alarm relays will toggle to there alarm-active state for ~2ms (i.e. change from
activated to deactivated or visa-versa depending on the Relay Energized on
Alarm configuration)
20
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.
VSWR Alarm Enable - Check the VSWR Alarm Enable box to monitor the
VSWR reading and activate the alarm if the VSWR exceeds the Trip Point for
more than thirty seconds, is equal to or slightly greater than the Trip Point and
reverse power is increasing or immediatly if the VSWR is much greater than the
Trip Point.
VSWR Relay Energized on Alarm - Checking this box will cause the VSWR
alarm relay to energize if the VSWR alarm is active and de-energize when the
alarm is not active. Un-checking this box will cause the VSWR alarm relay to deenergize when the alarm is active and energize when it is not active. Unchecking
this box ensures a fail-safe alarm configuration.
This setting will determine which relay contact will be open and which will be
closed in the event of an alarm condition and influence the hard-wiring of the
VSWR relay contacts. Refer to the power/alarm connection instructions.
VSWR trip point - Specify the VSWR value that will cause a VSWR alarm
(select values from the drop-down list). This value is adjustable from 1.3 to 2.5
by increments of 0.1. Check the VSWR Alarm Enabled on Zero Power checkbox
to allow the VSWR alarm to trigger at very low forward power (< 2.5% of full
scale power).
High Power Alarm (forward power only) - Check the Enable box and spec-
ify the percentage of full scale at which an alarm will occur. The high power
value must be greater than the low power value. The maximum value is 125% of
full scale power. The alarm setpoint is entered as a percent of full scale. For
example, if you have a 500W full scale unit and would like an alarm when the
forward power exceeds 375 W, the alarm setpoint would be 375 / 500 x 100 or
75%. Enter 75 in the field and check the Enable High Power Alarm checkbox.
Low Power Alarm (forward power only) - Check the Enable box and spec-
ify the percentage of full scale at which an alarm will occur. The low power value
must be less than the high power value. The minimum is 0%.
Power Relay Energized on Alarm - Checking this box will cause the Power
alarm relay to energize if the Power alarm is active and de-energize when the
alarm is not active. Un-checking this box will cause the Power alarm relay to
de-energize when the alarm is active and energize when it is not active.
Unchecking this box ensures a fail-safe alarm configuration.
This setting will determine which relay contact will be open and which will be
closed in the event of an alarm condition and influence the hard-wiring of the
Power relay contacts. Refer to the power/alarm connection instructions.
Trigger Alarm Button - After you have set or made changes to alarm settings,
you can use the Trigger Alarm button to test the alarms (messages, relay, TTL outputs). If the Config password is enabled, you will be required to enter the password
before you can test the alarm settings.
21
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).

Network Tab
In the Networking tab (Figure 14 on page 23), you can specify the following information about the address of the ACMI: IP address, subnet mask, gateway IP,
DHCP host name, and whether or not DHCP is used.
An IP address is required even if you connect the BPM-E directly to a computer
that is not on a network. Contact your IT professional for assistance in determining the IP address, subnet mask, and information about DHCP use and name.
22
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. The ACMI needs to be connected to a computer or server that
has email capabilities. Contact your IT professional for assistance in determining
the SMTP server IP and port. The text you enter at the left of the @ symbol in
the From email address will uniquely identify this ACMI in all sent emails. Use
text that will identify the ACMI and its location. The text at the right of the @
symbol is the email domain information for your server.

screens and features by clicking on the Help button at the left side of the screen.
25
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. The alarms will be monitored only when the end of
the PPT Delay is reached and the PTT logic input is still asserted. This prevents
false alarms while monitoring for low power and high VSWR.
Note: The VSWR Alarm Enable and/or Low Power Alarm Enable
must be enabled (checked) in order for these alarms to activate after a
PTT logic event and delay.
Setting Push-to-Talk
1. Open the Power Monitor Options dialog.
2. Do one of the following:
Check the Enable checkbox to turn the Push-to-Talk feature on.
Uncheck the Enable checkbox to turn the Push-to-Talk feature off.
3. Enter any value for the time up to 14 sec.
Note: The time actually programmed on the ACM will be a multiple
of 156.25 ms. For this reason, the time displayed will be slightly different from the time set. The actual delay from the PTT signal is uncertain
because the PTT signal is asynchronous to the internal measurement
samples. The uncertainty is +/- 156.25 ms.
Figure 18 Push-to-Talk
26
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.
The tables below show the forward and reflected range and resolution for the
100 W and 500 W ACMs for the various gain settings:
