RTR-4 Standard Wireless Configuration
Wireless Option
The RTR-4 Wireless Option is an alternative to connecting the
controller, X-Ray imager, and XR200 X-ray source with cables.
Wireless operation simplifies system setup and use by
eliminating the signal cables and provides greater controller to
target distances. The Wireless systems adhere to the frequencies
and protocols of the WiFi, IEEE-802.11b standard.
Radio-frequency energy between the imager and the controller
combined with the radio-frequency energy to the X-ray receiver is
at a very low intensity. When the Integrated Imager is more than
50cm (1.5ft) away from a target device, the RTR-4 Wireless
operation complies with the Hazards of Electromagnetic
Radiation to Ordnance (HERO) specifications. This consideration
is only relevant if the RTR-4 is being used with potentially
explosive devices.
The data transmission frequency of the Imager radio module and
the controller is between 2.4000 and 2.4835GHz, and is
spread-spectrum and frequency-hopping, according to the
IEEE-802.11b-1999 standard, and is further encrypted to
minimize snooping or spoofing. The frequency used when
transmitting to the X-ray source receiver is about 418MHz for US
usage and about 433MHz for European usage, which is very low
power. The frequency is coded with a sequencing 64-bit security
code to minimize the possibility of unintended source firing.
The wireless option adds the following components to the RTR-4
standard configuration:
• WiFi NIC.
• Imager transceiver.

• 2.4GHz screw-on transceiver antenna (ANT 1) for the imager
transceiver provides signals for communication with the
controller.
• 418MHz or 433MHz screw-on transmitter antenna (ANT 2)
for the imager transceiver provides signals to the X-ray
Receiver.
• Optional source transceiver with short antenna and connector
cable for alternate X-Ray sources.
WiFi NIC
The Wifi NIC is a PC interface transceiver card that fits into the
notebook Personal Computer Memory Card International
Association (PCMCIA) slot. This card transmits and receives data
to the Imager Transceiver radio module attached to the RTR-4
Imager.
Imager Transceiver Radio Module
The Image Transceiver radio module is affixed to the RTR-4
Imager with quarter turn clamps.This module transmits and
receives data to the controller PC and transmits a trigger signal
to the X-Ray receiver unit. A 3m (10ft) cable is available to permit
placement of the Imager Transceiver radio module remotely from
the imager to remove radio frequency energy from the immediate
area of the suspect package. This cable connects from the radio
module connector to the Imager at the receptacle located to the
left of the radio module bulkhead connector.
Internal Source Receiver
A receiver within the X-ray source receives the trigger signal from
the Imager radio module to fire the X-ray pulses. A label on the
XR200 source indicates that the source is equipped with an
internal receiver. All other sources use the externally mounted
source receiver.
Optional Source Receiver (Externally Mounted)
An optional source receiver is affixed to the X-ray source by a
velcro strip and connected to the source by a short cable. The
externally mounted source receiver is not used on the current
model XR200 source equipped with the internal receiver. All other
sources require the external receiver to be used in the wireless
configuration. The X-ray receiver unit receives a signal from the
Image Transceiver radio module and fires the X-ray source. It has
three components, the body, antenna, and connecting cable.
Cables are available that can accommodate any of the four X-ray
sources manufactured by Golden Engineering. The externally
mounted X-ray receiver unit is powered by a standard 9-volt
alkaline battery and has a power switch with an indicating LED.
System Description, Setup, and Quick Start RTR-4 Operator’s Manual

Setting up the RTR-4
There are two setup configurations for the standard RTR-4, the
wired configuration and the wireless configuration. There are
some positioning related issues that apply to all setups that the
operator must be aware of during the setup process.
Distance Adjustments
The distance between the source and the imager determines the
target X-ray illumination. Although a distance of approximately
50-100cm (20in-40in) between the X-ray source and imager is
recommended to provide a flat field image without sacrificing
penetrating power. This separation distance can be decreased to
penetrate thicker or denser materials, or increased to provide a
flatter field for very thin objects. Regardless of the distance
between the X-ray source and imager, it is usually better to place
the suspect object as close to the center of the imager as possible
to make the edges of objects sharper.
The further the suspect object is away from the imager and the
closer to the source, the larger its projected image, and the larger
its features appear in the acquired image. This can be used to
magnify small features, but will result in fuzzier edges. Objects
that are closer to the imager more closely reflect their true
dimensions.
Position Adjustments
The imager’s active area, denoted by the white rectangular
outline on the flat side of the imager (the face), should be
positioned as close as possible to the target object. The X-ray
source should be positioned approximately 50cm-100cm
(20in-40in) from the imager with its beam centered on and
perpendicular to the imager face. The imager is oriented so that it
is located as close to the ground as possible. The X-ray source is
set on the ground or in a slightly elevated position so the source’s
beam is centered on the imager’s face.
If needed, the imager can be used in an inverted position, such as
suspended from a rope or wire, placed on a tripod, or on its side
for imaging tall, narrow objects. An Image Orientation Indicator
in the marked corner of the image shows the orientation of the
object when the image was acquired. Regardless of the
orientation, the image appears on the controller screen as though
the imager was positioned with the handle on top. The image can
be rotated to the actual orientation using the RTR-4 software.

Software Description
The RTR-4 imaging software has many unique operating features
differing from the MS Windows® OS installed on the controller
notebooks. RTR-4 operators must be familiar with the Windows®
OS. This manual does not cover Windows® operation.
Information and training on Windows® may be located at
http://www.microsoft.com. RTR-4 application-specific features
and commands are listed and described in the following
paragraphs.
RTR-4 Functions
In most cases the RTR-4 commands can be accessed by:
• The pull-down menus listed in the Main Menu bar at the top
of the screen.
• A button on the toolbar displayed under the Main Menu bar.
• The Function Keys (F1-F12) located at the top row of the
keyboard.
• Various keys or key combinations (refer to the Key Map
selection under the Help pull-down menu for more
information).
• The RTR-4 application may be operated using the keyboard in
the advent of a mouse or pointing device failure.
Once the RTR-4 is set up and configured, the operator shall
launch the imaging software and verify that it is running
normally and properly configured.

Images are acquired with the RTR-4 using an imaging and
modification software program installed on the RTR-4 system.
The RTR-4 Main Menu screen is a standard Windows-based
Graphical User Interface (GUI) activated through onscreen
pull-down menus and toolbar buttons as well as keyboard
commands.
The RTR-4 software includes a database feature that lets the user
record information about an image such as operator name, date of
acquisition, location, project, type of image, X-Ray source and
serial number, and any comments about the image. This
information can then be retrieved, viewed, sorted by category, and
changed as needed to provide an accurate record of acquisitions
and modifications, and assist the user in locating and organizing
images. The database function is enabled in the Preferences
menu, and accessed through the File menu.
The operator must be familiar with the RTR-4 software pull-down
menus, dialog boxes, and toolbar buttons. The figure below shows
the Main Menu screen as it appears at startup.

During image acquisition, a progress bar is displayed, showing
progress as the image is transferred the Original buffer. When
finished, the system returns to the main screen and the image is
displayed.
An Acquire request can be canceled at any point by selecting
Cancel or pressing Esc twice. The Cancel or Esc commands
return the user to the Main Menu.
COMMAND DESCRIPTION
Acquire... (F1) When selected, the system waits the
number of seconds specified in the Delay
Timer field, then the X-Ray source fires
for the specified number of pulses and an
image is acquired.
Sum... Used to collect an initial image, then
subsequent acquired images are added
to the existing image. This operation
may be repeated as often as the operator
desires. This command is useful when
the target object is thick or made of a
dense material.
Enable Acquire When enabled (checkmark present), the
Acquire command is enabled and the
source can fire. When disabled (no
checkmark), the Acquire command is
disabled and the source will not fire. A
password will be required to re-enable
this function.

Fire and Sum X-Ray Dialog Box
Selecting Fire and Sum X-Ray command captures the first
image. The Acquire dialog box appears again automatically. If the
first image is adequate, select Cancel. If not, set the option
values and select Fire and Sum X-Ray again. This adds the
newly-acquired image to the sum of the previous images.
Using the Sum command can help produce images with superior
signal-to-noise ratios (SNR), by adding multiple acquisitions,
thus achieving higher grayscale values in the resulting image. Be
sure the Contrast Stretch is set to Default before starting so the
image does not wash out prematurely.
Disable Acquire
The Disable Acquire command is depicted by button at
the end of the toolbar. This button is only visible on those systems
which do not have the optional Interlock Safety Key. When the
button is depressed (the default state) Acquire is enabled and the
system responds as normal. When this icon is enabled, the user is
prompted to enter a password. This password will be required to
re-enable the Acquire command. The password is not retained
for future use; a new password is requested each time the function
is activated. This function acts as a software safety interlock, and
can be used to prevent another user from accidentally firing the
X-Ray source.

The Database Function
Enable Database Description
The RTR-4 software contains a database function that can be used
to collect, track, analyze, import and export images and related
information conveniently and efficiently. Use of the database
functions is optional and is enabled by checking Enable
Database on the Preferences menu.
When the Enable Database option is unchecked, the software
operates without the ability to append related data to displayed
images. When the Enable Database option is checked, the
operator has the opportunity to enter various details about an
image, to append related data to the image, and to append several
X-ray images to the active incident.
Database Structure
The database organizes and collects data related to an “Incident.”
An identified incident can have many X-Ray images, digital
RTR-4 Operator’s Manual System Operation
120300 Rev. D SAIC Proprietary 4-49
photos, audio, video, and other files appended to it. The general
relation ship is:
A more specific example shows one possible arrangement of files
that can be appended to an incident. In this case, the incident has
some notes, a digital photo and four X-ray images appended to it.
The X-ray images have from zero to four files appended to them
which include notes, digital photos, and in one case an audio file.
The database function allows for many incidents to be recorded.
Each incident can have many associated files and images
appended to it. Each image appended to an incident can
additionally have many associated files appended to the image.
Incidents and their associated files can be exported to archive the
data outside of the RTR-4 system. Pre-existing incident files can
be imported to add to data and images in an existing database.
This facilitates backup and data management.
All data related to an incident can be imported and exported to a
central point or database allowing the collection of incident data
for legal use, statistic trending, and intelligence analysis. An
entire incident, along with the associated RTR-4 images and all
appended files may be saved to disk or CD by selecting

display may be wiped off using a damp, lint-free cloth while the
power is off.
Disk Space
Hard disk drive and floppy disk file space can be recovered by
deleting old images that are no longer needed, or those that have
been backed up to an external hard drive, ZIP disk or CD-R. Use
the Delete option in Windows Explorer for this purpose.
Charging Batteries
It is recommended that unused and spare batteries be recharged
every month while in storage. The Imager and controller batteries
can be recharged by connecting the external power adapters when
they are not in use. There are two different battery chargers for
the DeWalt XR200 battery. One will only work on 110 Vac, 60 Hz,
and the other will only work on 220 Vac/50 Hz. Attempting to use
the battery charger with the wrong AC supply is very likely to
damage the battery charger and possibly the battery. Please
verify compatibility before connecting the charger to a power
source. Batteries should be disconnected from the charging once
they are fully charged.
Charging the Source Battery
The source battery is charged on an external battery charger.
Remove the battery from the source and plug it into the charger
to charge. A fully discharged battery can be charged in
approximately one hour. However, observe the LED indicator on
the charger to monitor battery charging progress. Be sure to
remove the battery when it is fully charged.
Charging the Imager Battery
The battery in the imager can be charged while it is in the imager
unit. Connecting the external power adapter to the Imager,
whether in use or not, will charge the battery. Observe the LED
indicator to monitor battery charging progress.
Imager batteries may also be charged using the external
imager-battery charger provided. The red and green LEDs on the
charger unit will indicate the condition and charge of the battery.
Replacement Integrated Imager batteries must meet or exceed
the specifications for a DR-35S 10.8Vdc 3800 mA/hr battery.
Nickel metal-hydrate (NiMH) is the only acceptable battery type.
Charging the Notebook Controller Battery
The RTR-4 Controller internal battery must remain charged to
ensure that the set is always ready for deployment. Connecting
RTR-4 Operator’s Manual System Operation
120300 Rev. D SAIC Proprietary 4-59
the supplied external power adapter to the notebook while it is not
in use will recharge a discharged battery. Using the external
power adapter while the notebook is in use will also charge a
discharged battery, but at a slower rate. Check with appropriate
notebook manufacturer documentation for recharge times.

3. X-ray Receiver unit and Receiver-to-Source cable.
4. Power Transceiver unit.
5. Adapter cable for optional medium-range antenna unit.
6. Tall screw-on transceiver antenna.
7. Short screw-on transmitter antenna.
8. Two Power Transceiver-to-Imager cables.
9. Orinoco WiFi NIC PCMCIA card.
Power Transceiver
The Power Transceiver unit has three functions:
• Provides power to the imager previously supplied by the
controller (in the CU-4 case) or the external power supply (in
the notebook case).
• Facilitates wireless communication between the controller
and the imager.
• Sends the wireless signal from the imager to the x-ray source
for firing x-rays.
The Power Transceiver unit has five assemblies:
• The black chassis
• Antenna 1 (tall, transceiver antenna)
• Antenna 2 (short, transmitting antenna)
• The blue Power Transceiver-to-Imager cable for
controller-and-imager communications
RTR-4 Operator’s Manual
120300 Rev. D SAIC Proprietary 5-3
• The gray Power Transceiver-to-Imager cable for
imager-to-x-ray-source communications
The chassis houses all the active components, the battery, the
imager-to-controller transceiver, and the x-ray transmitter.
Antenna 1 provides signals for communication with the
controller; Antenna 2 provides signals to the X-ray Source
Receiver. The blue cable provides communication to the imager,
and the gray cable (with one red strain relief and one yellow)
provides communication from the imager for x-ray firing
purposes.
The Power Transceiver has a convenient briefcase-style handle
and contains a 10.8-Volt smart battery that is the same type as
provided with the CU-4 controllers. This battery can be recharged
using either the single-slot or the dual-slot charger sometimes
provided with the RTR-4 controllers, or in the RTR-4 CU-4
controller's battery compartment. The Power Transceiver also
has a power switch and a power-indication LED as shown in
Figure 5-2. The battery is in use whenever the power switch is on
and the LED is illuminated. (Early versions have a red LED; later
versions have a green LED.)
Radio-frequency communications between the Imager and the
Controller combined with the radio-frequency communications
with the X-ray Source Receiver are very low intensity. When the
Power Transceiver is more than 50cm (1.5 feet) away from a
target device, then the RTR-4 Wireless Option complies with
HERO specifications. (If the RTR-4 is not being used with
potentially-explosive devices, then this specification is
irrelevant.)
The transmission frequency of the Power Transceiver when
communicating with the imager is near 2.4GHz. This
communication is done between 2.4000 and 2.4835GHz, is
spread-spectrum and frequency-hopping, according to the
IEEE-802.11b-1999 standard, and is further encrypted to
minimize snooping or spoofing. The frequency used when
transmitting to the X-ray Receiver is about 418MHz, is very low
power and is coded with a sequencing 64-bit security code to
minimize the possibility of unintended source firing.
Externally Mounted X-ray Source Receiver Unit
The X-ray Source Receiver unit receives a signal from the Power
Transceiver and fires the x-ray source. A detachable cable can
connect to any of the four x-ray sources manufactured by Golden

Power Supply Options
The CU-4 controller has a power-saving feature that darkens the
computer screen if not used for two to four minutes. Pressing the
shift key or moving the mouse reactivates the screen from the
power-saver mode. Do not press any other key as it may perform
an undesirable function.
The CU-4 controller automatically switches between internal
battery, US standard 110Vac, and international standard 220Vac
line power. The system is frequency-insensitive between 45 and
65Hz. The controller also powers the RTR-4 imager, so no special
power consideration is required for the imager.
The list below shows the power options for the Controllers for the
CU-4 and Notebook systems. Appropriate cables are provided for
each option.
RTR-4 Operator’s Manual
5-8 SAIC Proprietary 120300 Rev. D
• 110-220Vac 50-60Hz connection to local power grid (standard
operation).
• External DC power from an automobile cigarette lighter
receptacle (option)
• External battery power (option).
Battery Power
A 10.8Vdc rechargeable battery is located in the hinged
compartment below the keyboard of the controller. A fully
charged battery allows about 60 minutes of continuous operation.
The battery in the controller automatically begins recharging as
soon as the unit is plugged into a line power outlet, and takes
approximately eight hours to completely recharge. The controller
does not need to be powered up for recharge, but it does need to be
connected to a standard line power source.
An optional external battery charger can charge optional spare
batteries. Fully recharging a discharged battery with an external
charger takes about three hours.
A red LED on the CU-4 controller display panel will begin to flash
when battery power is low. When this occurs, images should be
saved and the system should be shut down as soon as possible, or
the controller should be connected to a standard line power
source.
Notebook Controller with Battery Box
The Notebook configuration uses a standard notebook PC as the
Control Unit. The Notebook Controller has the following
components:
• Pentium-series processor.
• Color flat panel display of at least a 12.1in (31cm) viewing
area, internal hard disk drive.
• 1.44 MB floppy disk drive.
• CD-ROM drive.
• Modem.
• Communications port.
The communications port provides connection between the
controller and the X-ray Imager. This port includes an internal
RTR-4 Operator’s Manual
120300 Rev. D SAIC Proprietary 5-9
rechargeable battery and an external power supply which can be
used to power the unit and also to recharge the internal battery.
Note that the adapter cable connects between the
communications port of the Notebook and the 50m reel cable.
Notebook Battery Box
The notebook controller has a Battery Box that is necessary to
power the Standard-View Imager and also routes communication
and image data signals between the Imager and the Notebook
Control Unit. This unit houses a rechargeable battery, which
provides several hours of operation for the Imager.
A green light indicates when the power is being supplied, this
requires that the Battery Box switch be in the ON position and
that the communications cable is properly plugged in. An external

battery-charging unit is provided, and the battery is easily
removed and replaced in the unit.
Optional Safety Interlock Key Box
The RTR-4 Notebook system offers an optional Interlock Key Box
which enhances the operators control of x-ray firing. This safety
feature is connected between the Control Unit pigtail cable and
the main 50-m signal wire, and makes use of the existing
connectors on these cables.
A serial communications cable is also required for this
configuration. This extra cable is a standard RS-232 cable
terminated with 9-pin plugs on either end. One side connects to
the Interlock Key Box, and the other is plugged into the COM port
on the rear panel of the Notebook Controller. This connection is
required so that the RTR-4 software can detect the orientation of
the key.
Previous Model Imagers
Introduction
This chapter describes the Standard-View Imager available for
use with the RTR-4 system.
Standard-View Imager
Description
The standard-view imager uses a compact solid-state camera.
Electro-optical signal processing circuitry records images
captured by the Imager unit's X-ray signal acquisition screen and
transmits the acquired images to the Controller (CU-4 or
Notebook.)
• Dimensions: 30cm x 34cm x 18cm (11.75in W x 13.25in H x
7.0in D)
• Field of View: 20 x 27cm (8in x 10.7in)
• Weight: 4.5kg (10lb)
RTR-4 Operator’s Manual
120300 Rev. D SAIC Proprietary 5-11
• Power: 12Vdc (supplied by CU-4 Controller’s Control Unit or
the Notebook Controller’s Battery Box.)
X-Ray Source & Imager Relationship
When acquiring an image, the target object must be positioned so
that it is as close as possible to the Imager’s signal acquisition
screen (face) which is denoted by the white rectangular outline on
the flat side of the Imager unit.
The X-ray source unit should be positioned approximately
60-90cm (24-35in) from the Imager with its beam centered on and
perpendicular to the Imager face.
The two large knobs on the side of the Imager unit must be
loosened prior to adjusting the imager’s handle. If the knobs are
not sufficiently loosened before adjusting or moving the handle,
the Imager may be damaged.
When scanning objects on the ground that cannot or shouldn’t be
moved, the Imager is oriented so that its face is as close to the
ground or working surface as possible.
RTR-4 Operator’s Manual
5-12 SAIC Proprietary 120300 Rev. D
The Imager handle is used to support the Imager so that its face
is nearly vertical. The X-ray Source is level with the Imager (or
slightly elevated) so that the X-ray Source’s beam is centered on
the Imager’s signal acquisition screen. The object being imaged
may need to be elevated and the X-ray source must be elevated for
the X-ray Source unit’s beam to be properly centered on the screen

Over Pulse Protection
Each Golden Engineering source has a duty cycle that sets the
maximum number of pulses that can be produced in a given time.
This is to prevent overheating in the source and stressing the
battery. The RTR-4 software will prompt the operator should a
selection be made that would overpulse the selected X-ray source.
Miscellaneous Accessories
