1. SYSTEM OVERVIEW
1.1 Introduction
The WEATHERPAK®EOC measures wind speed, wind direction, air temperature and GPS.
Options for the WEATHERPAK®EOC include relative humidity, barometric pressure, gamma
radiation sensor, radio transmitter, base station, and 3 types of software; INTERCEPT®(single
work station), INTERCEPT®(Network version up to 10 users), and INTERCEPT®(network
version up to 50 users).
WEATHERPAK®EOC was specifically designed for use for emergency management purposes.
The following is a list of some of the features that make the WEATHERPAKTM EOC unique:
•WEATHERPAK®EOC features an advanced electronic interface, which allows the
use of features such as GPS, the EOC’s unique automatic networking capability, as
well as future enhancements as they are needed.
•The wind sensor is an advanced technology, “ultrasonic” style anemometer. The
ultrasonic wind sensor has no moving parts, is very accurate (particularly at very low
wind speeds), and does not require periodic calibration.
In addition to the above features, EOC shares the following with the rest of the WEATHERPAK®
line of products:
•May automatically update CAMEO®/ALOHA®, CHARM®, MIDAS®and other plume
modeling software programs.
•Built-in electronic compass allows the WEATHERPAK®EOC to be set up in any
orientation – will automatically determine True North and give you true wind
direction.
•The electrical connections are designed to be intrinsically safe and the housing and
tower are constructed of 6061-T6 aluminum, a non-corrosive and non-sparking alloy.
•Designed to withstand decontamination procedures. The WEATHERPAK®EOC
housing is double O-ring sealed and dried with a desiccant to protect the electronics
against moisture.
•All electronics are grounded at a single point to protect the WEATHERPAK®EOC
against EMI (electro-magnetic interference) and RFI (radio frequency interference),
thus assuring reliable data and transmission.
•Designed to meet MIL-STD-461E (EMI) and MIL-STD-810F (extreme environments).

WEATHERPAK®EOC
Operations & Maintenance Manual
P/N: 0302-117-004 Rev. 0 2
This manual will familiarize you with the installation, operation, and maintenance of the
WEATHERPAK®EOC. Please read all of the instructions before attempting to operate or
troubleshoot the system.
1.2 Siting Considerations
1.2.1 Compass Accuracy
The WEATHERPAK®EOC contains an electronic compass for automatic alignment to True
North. If placed laterally near a large mass of steel or other magnetic material, an erroneous
compass reading may result. (The top of a van is OK, but next to it is not an ideal location). Try
to place the WEATHERPAK®EOC at least 30 meters laterally from large vans, busses, cranes,
metal buildings, etc.
1.2.2 Proper Wind Measurement
Select a site that is as unobstructed as possible. Structures, trees, terrain, etc. will disrupt the wind
flow for a considerable distance. The WEATHERPAK®EOC should be placed approximately 30
ft (10 meters) above the ground and ten times the height of an obstruction away from that
obstruction (e.g. should be 400 ft from a 40 ft tall building). This is a guideline, not a rule.
1.3 Data Message
The raw data message being transmitted by the WEATHERPAK®EOC will look similar to the
following:
1329,2.19,140,67.7,23.2,2.9,187,73.7,11.9,2018,1008,27,2661,4,1439,4735.705,

2. METHOD OF OPERATION
2.1 Introduction
This section provides detailed information about the system components and their interactions.
2.2 System Power
2.2.1 Power Over Ethernet (POE)
Power is supplied to the WEATHERPAK®EOC via a Power Over Ethernet (POE) Injector. The
POE Injector is an indoor piece of equipment requiring an AC outlet providing 100-240V AC
50/60 Hz (see Figure 2.1). The POE Injector converts AC power to POE DC power and sends the
DC voltage to the POE Splitter (see Figure 2.2) over a standard Ethernet cable. The POE splitter
is housed in the junction box below the WEATHERPAK®EOC.
Figure 2.1 – Power Over Ethernet Injector

2.3 System Signal and Data Flow
Data flow from the WEATHERPAK®EOC is via the same Ethernet cable that provides power to
the WEATHERPAK®EOC. A single Ethernet cable provides power and returns data to the
network.

2.4 Sensors
The system uses COTS (commercial off the shelf) sensors. A brief description of each sensor,
including sensor specifications, is provided in the following sections.
2.4.1 Wind Sensor
The wind sensor measures both horizontal wind speed and wind direction. The wind sensor is
mounted at the top of the WEATHERPAK®EOC so that disturbance from ground objects is
minimized. The wind sensor has an array of four equally spaced transducers in a horizontal plane
used to determine horizontal wind speed and direction. The measurement principle is based on
transit time, the time it takes for the ultrasound to travel from one transducer to another. Transit
time is affected by wind speed along the ultrasonic path. The transit time is measured in both
directions. For zero wind speeds, both the forward and reverse transit times are equal.

2.4.2 Ambient Temperature / Optional Relative Humidity (AT/RH) Sensor
The AT/RH sensor is housed inside the sealed WEATHERPAK®EOC. The output voltage of the
probe ranges from 0 to 1 VDC. Output voltages from the sensor are sent to the ZENO®in the
WEATHERPAK®EOC for processing via an integral cable.
The radiation shield protects the sensor from incoming short wave solar radiation as well as
outgoing long wave radiation and provides excellent sensor contact with the incoming ambient air.

2.4.3 Barometer (Optional)
The Barometer is housed in the WEATHERPAK®EOC. The data is sent to the ZENO®where it
is processed. The system uses atmospheric pressure and site-specific constants to compute
altimeter setting. The sensor is a versatile electronic barometer featuring high accuracy, low
power, wide operating temperature range with RS-232 serial data I/O. An accuracy of ±0.3 hPa
rms is maintained over the entire specified operating pressure and temperature range.

2.5 WEATHERPAK®EOC
The WEATHERPAK®EOC consists of a ZENO®Datalogger, optional barometer, temperature
sensor, optional relative humidity sensor, compass, communications link, and power supply
circuitry in a sealed weatherproof enclosure. The WEATHERPAK®EOC sends control and
polling signals to the sensors and receives data signals from the sensors.
The compass automatically aligns to magnetic north. If placed laterally near a large mass of steel
or other magnetic material, an erroneous compass reading may result. (The top of a van is OK,
but next to it is not an ideal location). Try to place the WEATHERPAK®EOC at least 30 meters
laterally from large vans, busses, cranes, etc.
2.5.1 ZENO®
The ZENO®accepts and stores sensor data from the AT/RH sensor, barometer and wind sensor. It
also checks alarms and control functions (diagnostic inputs) including ZENO®Datalogger power
monitor. Analog data are converted to serial digital data with low (12 bit, 10,000 samples/s, 2
channels maximum), high (15 bit, 10 samples/s), or ultra-high (18 bit, 2 samples/s) resolution.
The ZENO®Datalogger processes the sensor data in a 32-bit microcontroller and then sends the
processed sensor and other data in RS-232 serial format. The microcontroller allows extremely

WEATHERPAK®EOC
Operations & Maintenance Manual
P/N: 0302-117-004 Rev. 0 8
fast and powerful computing of multiple routines and uses advanced power management for very
low power consumption. A true real-time executive is used to achieve multi-tasking which
samples and communicates simultaneously. The ZENO®Datalogger operates using embedded
firmware. The SRAM stores all sensor and program settings. Functions include analog signal
conversion, digital input/output, serial communication, programming, and data memory. A real-
time clock is also provided.
2.6 Software
The system software consists of firmware running in the WEATHERPAK®EOC and application
software typically loaded on a PC or server. The software includes a data recorder, database,
algorithms, graphical user interface and a communication module for sending messages.
Software running on the computer is divided into two major categories: communications and
processing and storage. The communications software can be run on the same CPU as the other
applications or can be partitioned off on another CPU if the communications requirements
warrant it.
