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:

System Description, Setup, and Quick Start
• 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.
4-26 SAIC Proprietary 120300 Rev. D
RTR-4 Operator’s Manual System Operation
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.

System Operation RTR-4 Operator’s Manual
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.
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.

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.
4-30
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.
4-48
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
SAIC Proprietary 120300 Rev. D

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

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.
5-2
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
SAIC Proprietary 120300 Rev. D
RTR-4 Operator’s Manual
• 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
Engineering. A strip of velcro is used to attach the receiver unit to the X-ray source unit.
120300 Rev. D SAIC Proprietary 5-3
RTR-4 Operator’s Manual
The Externally Mounted X-ray-Source Receiver unit is powered by a standard 9-volt alkaline battery and has a power switch with an indicating LED.

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.
120300 Rev. D SAIC Proprietary 5-7
RTR-4 Operator’s Manual
• 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 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.

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
• 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.
120300 Rev. D SAIC Proprietary 5-11
RTR-4 Operator’s Manual
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
Introduction
Miscellaneous accessories currently available for use with the
RTR-4 are the:
• Wireless Option Backpack.
• Notebook PC Configuration Accessories
Wireless Option Backpack
The RTR-4 wireless option backpack provides a compact, convenient way of moving and operating the RTR-4 Wireless
Option configuration.
The backpack holds the following items:
• the imager unit
• the X-ray source unit
• the controller unit
• the wireless option equipment (including the power/transceiver unit)
The backpack accessory uses the same imaging procedure as would be used in a standard work space. The case with the components inside can be worn as a backpack to carry the system to another location.
The RTR-4 backpack is used in conjunction with the normal transport cases. The items above are removed from their transport case and put into the RTR-4 backpack. The equipment is placed in the backpack for easy removal of the PC controller and
X-ray source, while the imager is left in the backpack connected
