Chapter 1 Introduction
Purpose and Function
The Bird 4043E Directional Power Sensors are digital power sensors. The 4043E
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 118 to 940 MHz. See
"Model Identification" on page 19 for specific
frequency ranges and model features. The 4043E sensor also provides a VSWR
reading.
Figure 1 4043E Power Sensor
The 4043E Power Sensor uses Ethernet communications for sensor control and
measurement data.
See
"Sensor Operation" on page 8 .
The 4043E Sensor is designed to transfer data over an Ethernet connection. The
power sensor requires an external power supply.
Each sensor is equipped with RF input and output connectors, one RJ-45
connector for Ethernet communications, a PTT connector, and a status indicator.
See
Figure 2 .

Chapter 2 Power Sensor Installation
The Bird 4043E Directional Power Sensors are designed to be used for
continuous RF power monitoring. The 4043E can provide real-time RF forward
and reflected power and VSWR measurements.
Ethernet Connection
The Ethernet connector is used to connect the 4043E to a PC or a network
router/switch. Measurement data is transported over the Ethernet connection
so the data can be viewed in a web browser. The configuration depicted in
Figure 4 is an example of one possible installation.
Since the 4043E is shipped with a static IP address, before more than one unit
can be added to a LAN, the IP address must be changed to a unique static IP
address or set to DHCP.
Direct PC Connection — A direct PC connection is a connection between a
PC and a single 4043E. This connection can be used to view the sensor’s
measurement data, however, if the sensor will be used with a LAN connection,
this type of connection must be used to change the IP address of the 4043E. See
"Direct PC Ethernet Connection" on page 5 .
LAN Connection — The 4043E may be connected to a router or switch so it
can provide measurement information through a LAN. A LAN connection can
provide the ability to monitor several 4043E sensors from a single PC.
Additionally, SNMP management software can be used to aggregate multiple
sensors and monitor their outputs. See
"LAN Connection" on page 5 .

RF Measurement Alarms
The 4043E power sensor can be set to display an alarm, and send SNMP
messages, for exceeding forward power and VSWR limits set by the user.
Alarms are controlled on the settings page, a threshold can be set for minimum
and maximum forward RF power in watts and minimum and maximum VSWR.
See
Figure 8 .
Figure 8 Alarm Settings
The alarm function may be enabled or disabled.
when enabled, a measurement exceeding a threshold will display an alarm
message in the Table View, see
Figure 9 .
When disabled, alarms are not displayed and no SNMP traps will be generated.
The alarms can be set to latched or unlatched.
When set to latched, alarm messages remain on the display until the Reset
Alarm button is clicked on the settings page.
When set to unlatched, alarm messages are only displayed while the threshold is
exceeded.

PTT Settings
PTT is used to prevent spurious alarms during periods when the transmitter is
not transmitting because alarm functions for that channel will only be possible
when the transmit button is engaged.
PTT is controlled on the settings page, PTT may be set to normally open or
normally closed logic, or disabled, see
Figure 10 .
The PTT terminals on the 4043E must be connected to the transmitter in the
correct logic state for PTT to operate correctly.
Figure 10 PTT Options
Zero Sensor
Zero Sensor is used if the 4043E sensor’s readings are not zero when the RF
transmitter connected to the sensor is off.
The Zero Sensor option merely applies a negative offset to the power reading
based on the value the sensor displays when RF is off.

Implement SNMP
The Simple Network Management Protocol (SNMP) feature is designed to
provide reliable Internet notification of an alarm occurrence. SNMP is an
Internet standard protocol for managing devices on IP networks.
SNMP network management software is required to implement SNMP. It is the
customers responsibility to ensure the destination computer is running suitable
SNMP management software.
Bird provides MIB files for use with the customers SNMP management software.
These MIB files allow the trap messages to be properly decoded. The MIB files
can be downloaded from the product page on the Bird website at;
“www.birdrf.com”.
The 4043E supports SNMP GET and SET commands, and can be configured to
send SNMP Trap messages. All of the 4043E’s SNMP commands can be found in
the MIB file.
GET and SET Commands
The SNMP manager can issue a GET request to read settings and power
measurements, and the SNMP manager can issue a SET request to change
settings.
GET
The SNMP GET operation is used by the SNMP manager applications to retrieve
one or more values from the 4043E.
The SNMP GET operation is used to query the scalar variables in a MIB. Each
variable is identified by its OID. The 4043E will respond with a return value or
with an error.
Sets
The SNMP SET operation is used by the SNMP manager to modify settings in the
4043E.
Perform an SNMP SET operation by providing the host name of the 4043E, one
or more OIDs along with its instance, and the new value. The 4043E processes
the request and assigns the new value to the MIB variable. If an error occurs, the
new value is not assigned.

Sensor Operation
12
SNMP Traps
Traps are messages sent to the SNMP manager by the 4043E when events occur.
To enable SNMP Trap functionality, connect to the 4043E User Interface, enable
Traps, and enter the SNMP Manager’s IP address. See
Figure 12 .
A trap message will be sent to designated host computers whenever the sensor
detects an alarm condition. See
Table 1 on page 13 .
