1INTRODUCTION
The RSDetection is the latest in the GE Reuter-Stokes line of Gamma Radiation Monitors. It
measures gamma radiation dose rates up to 100 R/h (1 SV/hr) and supports a wide range of
communication interfaces. This manual applies to all versions of the RSDetection, whose part
numbers are RS-S131-200-ERxxxx.
All references to RSDetection in this manual apply to all part numbers above unless otherwise
specified.
1.1 HARDWARE OVERVIEW
The RSDetection is a self-contained gamma monitor which consists of three major components.
1.1.1 High-Pressure Ion Chamber
The high-pressure ion chamber (HPIC) is a highly sensitive and stable detector for gamma
radiation. Gamma rays enter the argon gas, ionizing the gas and generating current.
1.1.2 Electrometer
The electrometer converts the ion chamber current to a value that can be read by the DAQ
board. The electrometer mounts directly to the ion chamber. It connects to the DAQ board
by a cable that supplies power to the electrometer and provides a communication
interface.
1.1.3 DAQ Board
The DAQ board gathers data from several internal inputs and supported external sensors.
A processor is used to gather sensor data and perform calculations. The data is stored in a
database for later retrieval.
The application firmware is stored in flash memory. It can be updated over the Ethernet
connection via the supplied configuration utility. This allows new features and program
updates to be installed without returning the product to the factory.
The DAQ board hosts an industrial grade SD card that contains the operating system, the
application and the database. This card is required to run the unit and should not be
removed.
The DAQ board implements a number of external connections:
Ethernet
Dedicated RS-232 serial
USBB connection that mounts as a serial port on the host computer
USBA to serial converters that communicate via RS-232 (maximum of 2
supported)
Users can request data and configure the system through these ports. These connections
are standard on all units.

1.2 OPERATIONAL CONCEPTS
1.2.1 Configurations
The unit behavior is driven by configurations that are associated with events and
measurements, as well as miscellaneous features such as serial ports, system operation,
and various other system entities. The configuration utility provides customization of all
the configurable parameters. A complete list is provided in the Configurations Tab section
in this manual.
1.2.2 Events
Events are data entities that are associated with sensors and have a fixed number of
states. For example, external power can be off or on, or a measurement can be above or
below its alarm limit. When an event changes state, there are two actions that may take
place depending on the configuration for that event:
1.2.2.1 Log to the Event Log
The prior and current states are recorded along with date/time and optional comments
concerning the event.
1.2.2.2 Notification
The unit can be configured to send the event state when the state changes. The actual
output is an XML event command containing the same properties that are logged. See the
Notifications section of this manual for further details.
1.2.3 Scalar Measurements
Actual data values are represented by measurements. Most measurements fall into the
category of Scalar Measurements. A scalar is expressed as a numerical value. Each
measurement has a unit type, such as volts or dose rate, and formatting information
defined by its associated configuration. See the Software Configuration Utility section of
this manual for complete descriptions.
1.2.4 Composite Measurements
There are some measurements whose data does not fit into a numerical quantity.
Currently there are two measurements in this category, the battery charger data and the
optional meteorological sensor. In these cases, a block of data is provided by the device.
There are scalar measurements which are derived from the composite data. For example,
the scalar measurement BatteryCurrent is taken from the composite measurement. A
consequence of deriving scalars from the composite is that the sampling interval of
battery current cannot be independently configured, since it is tied to the update interval.
In this example, to change the Battery Current’s UpdateIntervalSpan the composite
measurement Battery Status has to be changed and not the scalar measurement’s
UpdateIntervalSpan. The table below shows which scalar measurements role up to which
composite measurements. When changing the UpdateIntervalSpan for the parent
composite measurement subsequently all child scalar measurements also change.

1.2.5 Legacy Commands
These commands support a simple ASCII command set that is compatible with prior
generations of gamma monitoring products. Although most are supported, some are not
due to architectural differences. These commands are only supported on serial
communication channels via direct RS-232 or a USB connection (not supported on
Ethernet). A list of the supported and unsupported commands is described in the Appendix.
1.2.6 XML Commands
XML commands are new to the RSDetection unit and support all of the configurable
capability, measurements, and events. These commands and responses conform to the
XML standard widely used in internet data transfer. All of these make use of XML elements,
which typically have a start-tag and an end-tag with the content between them.
A description of these commands, which is beyond the scope of the user manual, is located
in a separate manual titled RSDetection Communication Manual, S131-200-COMM.
1.2.7 Notifications
Most of the communication between a connected computer and the RSDetection unit can
be accomplished by sending commands and receiving responses. Notifications can be
used to send information from the unit to the computer without a command. In the case of
events, these are generally sent when there is a change of state. For measurements a
notification is sent when a new sample is made, even if the value does not change as a
result of the update.
The three levels of control for sending notifications are described below.

RSDetection
User’s Manual
March 2016 S131-200-UM Rev A

g
RSDetection Level - In the RSDetection system configuration a NotifyEnable
property is available. If false then no notifications are sent even for those
individual notifications that are enabled.
Measurement/Event Configuration - Each event and measurement has its own
notification enable that inhibits or allows notifications for that one item.
Communication Channel - When a host computer establishes a connection
(Ethernet or serial), notifications are disabled by default. In order to start
notifications, a NotifyEnable command must be sent with the enable property
set to true. Reference the RSDetection Communication Manual for details of
this command.

Figure 1 Database Tables
Each sensor, if enabled, will record data to this database. Data for each sensor is recorded
based on the customer-specified logging interval. All data is an average value calculated
over the logging interval.
Sensors can be sampled every 5 seconds, but may be sampled less frequently if desired.
The electrometer is the lone exception. It is always sampled every 5 seconds and cannot be
changed.
