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
Operating 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 uninterruptible 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 applied.

Chapter 1 Introduction
Purpose and Function
The Bird 4043 Series Directional Power Sensors are digital power sensors. The
4043 Series power sensors are typically used to measure forward and reflected
average power on a 50 ohm RF transmission line with a maximum 500 watt
forward and maximum 50 watt reflected power levels in a frequency band with
an overall range of 144 to 940 MHz. See "Model Identification" on page 12 for
specific frequency ranges and model features. The 4043 sensor also provides a
VSWR reading.
Figure 1 4043 Power Sensor
The model 4043 power sensor is available with two different types of
communication interface:
RS-485 Serial Communication - designed for use with the Bird Channel
Power Monitor (CPM) in rack mounted communications systems.
See "Serial Communication Model" on page 2 .
Bluetooth Communication - designed for use with vehicle mounted
communications systems, or as portable test equipment.
See "Bluetooth Communication Model" on page 5

Chapter 2 Serial Communication Model
The 4043 Sensors with an RS-485 serial bus are designed to transfer data to and
from a CPM. The serial bus also serves as the power sensor’s power supply.
Each sensor is equipped with two RJ-25 jacks for serial communications, RF
input and output connectors, and a status indicator. See Figure 2 .

Each sensor is equipped with two RJ-25 jacks, either jack may be connected to a
CPM. The second RJ-25 jack may be used to extend the RS-485 bus to another
digital sensor. See Figure 3 on page 3 . Multiple digital sensors may be serially
connected in this fashion, allowing as many as 16 sensors to be connected to a
CPM.
If multiple 4043 sensors are to be connected serially, each one is assigned a
unique address via the CPM. When each 4043 is connected to the CPM, prior to
connecting any additional 4043 sensors, they must be assigned an address by
the CPM, only then may an additional sensor be connected serially.
A termination plug must be used in the open RJ-25 jack on the rear panel of the
CPM or the open RJ-25 jack of the final digital sensor in the chain.

available, see
"Model Identification" on page 12
RF Output N-Type (female) connector (shown), other connector types

"Model Identification" on page 12
Data Connectors
RJ-25 connector provides power and data connection. Only
one connector is required, second connector may be used to
extend RS-485 bus to additional digital sensors.
RJ-25 termination plug must be installed in unused jack or in
the Open port on the CPM.
Status LED Solid green: Power applied.

Serial Communication Power Sensor Installation
The Bird 4043 Series Directional Power Sensors are designed to be used for
continuous power monitoring of Land Mobile Radio (LMR) systems. The 4043
can provide real-time RF forward and reflected power and VSWR
measurements.
This procedure is an example of one possible cable configuration, based on the
connection diagram in Figure 3 .
1. Disable RF power for transmission lines to be disconnected.
2. Connect combiner's RF output cable to the 4043 RF input.

3. Connect 4043's RF output connector to the antenna cable.
4. Repeat step 1 through 3 for any additional 4043 power sensors.
5. Install RJ-25 termination plug in unused digital sensor RJ-25 port on the rear
panel of the CPM (if available), or in the last sensor installed in the digital
sensor chain.
6. Connect a data/power cable from the CPM to 4043 power sensor.
WARNING
Leaking RF energy is a potential health hazard. Never attempt to connect or
disconnect equipment from the transmission line while RF power is being
applied. Severe burns, electrical shock, or death can occur.

Note: Each digital sensor must have a unique RS-485 Bus address
when connected serially to the CPM. Connect the digital sensors
one at a time, enroll the sensor using the CPM front panel to
provide a unique address, prior to connecting additional sensors.
7. Configure the sensor via CPM front panel. Refer to the CPM Operation
Manual.
8. If additional 4043 power sensors will be connected, connect a data/power
cable to the open RJ-25 jack, connect remaining end of cable to additional
4043 sensor.
9. Repeat step 7 and 8 for any additional 4043 power sensors serially
connected to the CPM.
Note: Digital sensors require a terminator plug be installed in the
open Digital Sensor RJ-25 port on the rear panel of the CPM (if
available), or in the last sensor installed in the digital sensor chain.
10. If required, install RJ-25 termination plug in unused RJ-25 Jack of last digital
sensor in the chain.

Bluetooth Communication Model Installation
A connection may be established to a 4043 Sensor using the Bird RF Meter App.
See "Bluetooth Communication Model" on page 5 for additional information about
the Bluetooth operation.
1. If not previously connected to the RF Source, perform steps a thorough c .
a. Disable RF power for transmission lines to be disconnected.
b. Connect RF output cable to the 4043 RF input.
c. Connect 4043's RF output connector to the antenna cable.
2. Connect the 4043 sensor to a DC power source (Internal batteries, or a
suitable power supply. See "Bluetooth Power Sources" on page 8 ).
3. Press the pair button on the 4043 sensor.
Note: Perform the following steps within one minute.
4. Open the Bird RF Meter App.
5. Tap the menu icon at the top right of the screen.
6. Tap Network Scan.
The 4043 sensor will appear under the Found Devices heading.
7. Tap the 4043 sensor listed under Found Devices.
The App should connect to the device and display the sensor current
measurement readings.
Note: Use the RF Meter App’s Help content for instructions on
how to configure the App and sensor.
Pairing the 4043 Bluetooth Sensor with the Bird RF Meter App
First time pairing of a 4043 Sensor and a device running the Bird RF Meter App is
accomplished by pressing the Pair button on the 4043 Sensor, then initiating the
Bluetooth connection from within the RF Meter App.
Note: It is NOT necessary to pair with the 4043 Sensor through
the devices operating system.
After a device running the Bird RF Meter App has been paired with a 4043
Sensor it will no longer be necessary to press the pair button on the sensor for
future connections. The 4043 Sensor “remembers” the device to allow faster
connections via Bluetooth.
WARNING
Leaking RF energy is a potential health hazard. Never attempt to connect or
disconnect equipment from the transmission line while RF power is being
applied. Severe burns, electrical shock, or death can occur.
