The HCS300 combines a 32-bit hopping code generated by a non-linear encryption algorithm, with a 28-bit serial number and six status bits to create a 66- bit transmission stream. The length of the transmission eliminates the threat of code scanning and the code hopping mechanism makes each transmission unique, thus rendering code capture and resend (code grab- bing) schemes useless. The encryption key, serial number, and configuration data are stored in EEPROM, which is not accessible via any external connection. This makes the HCS300 a very secure unit. The HCS300 provides an easy to use serial interface for programming the necessary security keys, system parameters, and configuration data. The encyrption keys and code combinations are pro- grammable but read-protected. The keys can only be verified after an automatic erase and programming operation. This protects against attempts to gain access to keys and manipulate synchronization values. The HCS300 operates over a wide voltage range of 2.0V to 6.3V and has four button inputs in an 8-pin configuration. This allows the system designer the freedom to utilize up to 15 functions. The only components required for device operation are the but- tons and RF circuitry, allowing for a very low system cost. 1.0SYSTEM OVERVIEW Key Terms • Manufacturer’s code - a 64-bit word, unique to each manufacturer, used to produce a unique encryption key in each transmitter (encoder). • Encryption Key - a unique 64-bit key generated and programmed into the encoder during the manufacturing process. The encryption key controls the encryption algorithm and is stored in EEPROM on the encoder device. 1.1Learn The HCS product family facilitates several learn strate- gies to be implemented on the decoder. The following are examples of what can be done. It must be pointed out that there exists some third-party patents on learn- ing strategies and implementation. 1.1.1NORMAL LEARN The receiver uses the same information that is trans- mitted during normal operation to derive the transmit- ter’s secret key, decrypt the discrimination value and the synchronization counter. 1.1.2SECURE LEARN* The transmitter is activated through a special button combination to transmit a stored 48-bit value (random seed) that can be used for key generation or be part of the key. Transmission of the random seed can be dis- abled after learning is completed. The HCS300 is a code hopping encoder device that is designed specifically for keyless entry systems, primarily for vehicles and home garage door openers. It is meant to be a cost-effective, yet secure solution to such systems. The encoder portion of a keyless entry system is meant to be held by the user and operated to gain access to a vehicle or restricted area. The HCS300 requires very few external components (Figure 2-1). Most keyless entry systems transmit the same code from a transmitter every time a button is pushed. The relative number of code combinations for a low end system is also a relatively small number. These shortcomings provide the means for a sophisticated thief to create a device that ‘grabs’ a transmission and re-transmits it later or a device that scans all possible combinations until the correct one is found. The HCS300 employs the code hopping technology and an encryption algorithm to achieve a high level of security. Code hopping is a method by which the code transmitted from the transmitter to the receiver is different every time a button is pushed. This method, coupled with a transmission length of 66 bits, virtually eliminates the use of code ‘grabbing’ or code ‘scanning’. As indicated in the block diagram on page one, the HCS300 has a small EEPROM array which must be loaded with several parameters before use. The most important of these values are: • A 28-bit serial number which is me…

RTR-4 Portable Digital X-Ray Imaging System--Operator’s Manual Supplement 3-2SAIC Proprietary306847 Rev A Figure 3-1: RTR-4 Wireless Option Items Figure 3-2: Power/Transceiver Unit 1 2 3 4 5 67 8 9 RTR-4 Portable Digital X-Ray Imaging System--Operator’s Manual Supplement 306847 Rev ASAIC Proprietary3-3 The Power/Transceiver unit (Figure 3-2) 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, transceiving antenna) •Antenna 2 (short, transmitting antenna) •The blue Power/Transceiver-to-Imager cable for controller-and-imager communications •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 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 rovided 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 3-2. 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 Receiver are very low intensity. When the Power/Transceiver is more than 50 cm (1.5 feet) away from a target device, then the RTR-4 Wireless Option complies with the HERO specifications. (If the RTR-4 is not being used with potentially-explosive devices, then this specification is irrelevant.) RTR-4 Portable Digital X-Ray Imaging System--Operator’s Manual Supplement 3-4SAIC Proprietary306847 Rev A The transmission frequency of the Power/Transceiver when communicating with the imager is near 2.4 GHz. This communication is done between 2.4000 and 2.4835 GHz, 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 418 MHz, is very low power and is coded with a sequencing 64-bit security code to minimize the possibility of unintended source firing. Battery replacement procedures are described in Chapter 6. X-ray Receiver Unit The X-ray Receiver unit (Figure 3-3) receives a signal from the Power/Transceiver and fires the x-ray source. It has two components, the body and the cable. The detachable cable can accommodate any of the four x-ray sources manufactured by Golden Engineering. They are listed below in order of their appearance from top to bottom in Figure 3-4: • Inspector Model 200 (special cable) • XR-150 (special cable) • XRS-3 (standard cable) • XR-200 (standard cable) The Inspector Model 200 was discontinued by Golden Engineering in 1998, but the RTR-4 Wireless Option still supports it. The X-ray Receiver unit is powered by a standard 9-volt alkaline battery and has a power switch with an indicating LED. Battery replacement procedures are described in Chapter 6.
