No. 96-1886-01E Rev. 1.1 GTECH Aircon Radio (Model GWT154) PAGE 4 OF 72 1.0 INTRODUCTION 1.1 Purpose,Overview&ScopeThe purpose of this document is to provide details regarding the use of the GWT154 transceiver module as a cable replacement between GTECH online lottery terminals and associated peripherals. The GWT154 transceiver module is based on the IEEE 802.15.4-2006 standard, this wireless link provides a point to multipoint peripheral bus with low latency and modern security features. The link operates in the 2.4GHz band with low power, making it suitable for license-free worldwide operation. The link will use AES 128 bit authentication and packet encryption available as part of the 802.15.4 standard. It will also use EUI-64 (MAC address) filtering to keep rogue devices off the network. It relies on the GTECH online lottery terminal for initialization and authorization of End Device peripherals. This allows GTECH the ability to integrate the local security measures with field service installations and manufacturing operations, as well as to provide security audit trails, without on-site technical staff. This document describes the electrical and wiring considerations when interfacing the GWT154 module with a GTECH online lottery terminal and a peripheral. Peripheral devices include (but are not limited to) the following:  Ticket Scan  Accutherm Supreme and Accutherm Ultra printers  Customer Display Units  Jackpot Signs. 1.2 Audience This document is intended to be read by engineers and technical management. A general knowledge of common engineering practices is assumed. 1.3 ApplicableDocuments96-1886-00E, GTECH Wireless Peripheral Transceiver, Rev 3.1, June 2, 2010 96-0258-01, Spec Protocol 485 Bus Packet, Rev D 96-0320-01, RS-485 Physical Interface Specification, Rev C, September 2, 2003 33-0154-01E, System Diagram GWT154, Rev 1, June 3, 2011

No. 96-1886-01E Rev. 1.1 GTECH Aircon Radio (Model GWT154) PAGE 17 OF 72 3.9 RFModuleOperation Network is non-beacon enabled 802.15.4 Medium Access Control (MAC).  Security is CCM* with 128-bit encryption keys.  Random network encryption key assigned during initial commissioning.  Peripheral End Devices are at minimum RFD’s with radio always-on.  Data transfers are Direct mode (Indirect not supported).  PAN ID assigned network Coordinator short address. With the exception of a smaller maximum fragment size and longer/variable ACK latency, GTECH’s User Data payloads will pass through the wireless link transparently, with virtually the same GTECH485 protocol presented at both ends. The PAN Coordinator radio will be attached the GTECH Terminal Host CPU, which is responsible for initializing and managing the wireless network. Thus, the Terminal can control the RF channel and other infrastructure parameters, in addition to commissioning peripherals and controlling security. Only one radio may be connected to any single Terminal serial port. In a system where a single Terminal Host CPU is to control multiple Coordinator radios, a dedicated Host serial interface port must be allocated to each Coordinator radio. By operating the serial host interface at a higher data rate than the GTECH485’s original 19.2Kb, the latency introduced by packet buffering within the radio modules can be minimized. The radio module host serial interface will operate at data rates up to 230K BAUD. Due to the packet nature of the network, the typical data flow will proceed as follows: The Host CPU sends a GTECH485 packet to the Coordinator radio via the local wired 485 link. The wired serial stream is buffered by the Coordinator radio until the entire packet is received. The radio then encrypts the buffered payload using the network key (randomly generated during wireless network commissioning). The Coordinator radio then sends the secure packet to the Peripheral connected to the currently selected End Device radio. The Peripheral’s radio receives the packet, authorizes it, decrypts its encapsulated payload and sends the entire payload contents to the Peripheral’s Host CPU over the local 485 wired bus. The End Device radio acts as a local Host CPU proxy to its GTECH485 bus, sending the packet and receiving one of the ACK responses (ACK, NAK, CAN) from a Peripheral on the bus. The End Device radio encrypts and sends this ACK back to the Coordinator radio as a secure packet. The Coordinator receives and decrypts this ACK and, in the role of proxy for the Peripheral,
No. 96-1886-01E Rev. 1.1 GTECH Aircon Radio (Model GWT154) PAGE 18 OF 72 transmits the ACK back to the Coordinator’s Host CPU. Figure 9 - Typical Data Flow 3.9.1 BreakProcessingLegacy GTECH Peripherals recognize a UART Break condition on the GTECH485 bus as a hardware reset. The Coordinator radio hardware does not include dedicated UART Break detect hardware, but the Coordinator radio firmware will monitor the GTECH485 bus for a UART Break condition. In addition, the Host CPU may issue a Break command packet to the Coordinator. In either event, the Coordinator will broadcast a Break command packet to all the currently Associated End Devices in its PAN. The End Device radios will software self-reset which, by virtue of the radio’s power-on initialization sequence, will assert a Break on its wired 485 bus.

The Host CPU configures the radio with the required network parameters such as Channel and PAN before initiating network startup. 3.9.3 EndDeviceAssociationDevices previously joined to a PAN automatically attempt to associate with their joined network as soon as they are powered up. The TIMAC will issue an 802.15.4 Beacon Request on every channel enabled and wait to see if it receives a response from its PAN Coordinator. If an association attempts fail on all channels, there is a random 10-15 second wait time before the next attempt is made. 3.9.4 802.15.4MACAcknowledgeTransactionAt a low level, each unicast 802.15.4 data transmission is actually a transaction with acknowledgement. This low-level acknowledgement and retry mechanism serves to increase the reliability of the wireless link enormously. This functionality is hidden from the application layer and the user. The GTECH485 protocol ACK is actually a separate transaction. At the low level it looks exactly the same as any other data transaction. 3.9.5 TransmitPowerLevelThe TIMAC Application Programming Interface allow setting of the radio’s with a 1dB resolution

Either the Host can force it to use a particular channel, or the radio module can do an energy scan of all available channels. The Host CPU can also pre-set the PAN-ID or it can automatically select an unused PAN-ID during network commissioning. The GTECH 802.14.5 wireless network will be implemented as a non-beacon-enabled network. Often in beacon-less systems, an End Devices may still expect to periodically receive communication from its Coordinator, often referred to as a heartbeat. In the event an End Device does not receive a heartbeat within a reasonable period, the End Device may attempt to recover by scanning all channels and requesting to rejoin its coordinator if found. This feature is not implemented in this design. 4.2 DeviceJoiningOnce a wireless network PAN Coordinator radio has been configured and started, the peripheral radios may be joined to the PAN. End Device joining will be implemented in accordance to the 802.15.4 standard. Upon pairing activation by the End Device radio’s User Interface, the MAC will scan all 802.15.4 (mapped) RF channels by broadcasting a Beacon Request and registering any successful responses in a PAN Descriptor list. Once all enabled channels have been scanned, or the PAN Descriptor list is at maximum, the End Device will sequentially unicast an Associate Request to each of the PAN Coordinators found in the Descriptor list, and wait for a response. If it does not receive a response in a random amount of time (between TBD seconds) it will try the next PAN in the Descriptor list, or if only one PAN, retry. This time delay will keep the network from being overloaded with requests and reduce the chance of RF collisions with other End Device radios. When the Coordinator receives an Associate Request and successfully decrypts using the default factory key, it saves the End Device’s 64-bit EUI address in a list for later processing by the Host CPU. Subsequently, the End Device will issue a Data Request to the Coordinator, if the previous Associate Request was accepted, the Coordinator will reply with an Associate Response. The End Device has temporarily been joined to the PAN and will remain so until it is later permanently joined to the PAN, or it times-out. A failsafe timeout should be employed in the End Device radios during joining to ensure that if the sequence fails to end in success, the radio discards any joining parameters obtained, and return the radio to its inactive state. The Host CPU will determine the length of time the Coordinator will accept Association Requests; multiple End Devices may be associated during any given joining session. After terminating the association period, the Host CPU gets the EUI-64 address list from the Coordinator. Based upon each End Device’s EUI-64, the Host CPU will decide whether that device is allowed on the PAN. The Host CPU instructs the Coordinator to enter an End Device into the Access Control List
No. 96-1886-01E Rev. 1.1 GTECH Aircon Radio (Model GWT154) PAGE 22 OF 72 (ACL) by sending a configuration packet containing the device’s EUI-64. The Coordinator will create a unique 16-bit short address for the End Device to use in the Coordinator’s PAN and will verify that it has a non-zero network key from a previous join session, generating a random network key as required. A radio configuration packet is unicast to the End Device secured using the factory default key. If an End Device radio receives a Join PAN configuration packet from the Coordinator, it extracts its Short address and the network key. The End Device then sends a response packet back to the Coordinator secured using the new network key. The Short address and network key are saved in non-volatile memory when the MAC-layer Acknowledge is received. Upon receiving the Join PAN response configuration packet from the End Device, the Coordinator will also store the new End Device’s EUI-64 and Short addresses to the ACL in its non-volatile memory. Once the joining session has successfully completed, the Host CPU should initiate a communication test either automatically, or from a User Interface request. 4.3 DeviceSecurityThe “CCM*” security protocol within 802.15.4 will be used to encrypt data and authorize End Devices. The Coordinator generates a random network key at the time of commissioning. The random nature of the key is ensured by dedicated hardware in the CC2530 that samples bits in the I and Q data streams in the radio receiver

No. 96-1886-01E Rev. 1.1 GTECH Aircon Radio (Model GWT154) PAGE 24 OF 72 4.4 NonVolatileSettingsBoth the Coordinator and End Device radios must retain the PAN, EUI-64, Short Address, encryption key, etc., after a successful joining sequence. In addition, certain system configuration parameters like BAUD rate, transmit power, etc. may also be saved in non-volatile memory. The CC2530 may reserve sectors in its on-chip Flash memory to store non-volatile data. Once a CC2530 has been factory programmed with the executable code binary image, factory default key, EUI-64 and PIN, a Debug Lock bit is permanently set in Flash that prevents further access to the Flash memory image via the In-System-Programming (ISP) interface. Only the CHIP_ERASE command may be executed by the ISP after a CC2530 has been Debug Locked, allowing only the full erasure of the embedded Flash memory. It is important to note that after network commissioning; only the radios know the randomly generated network key. The Host CPU only knows of the End Devices by their Short Address and EUI-64. In addition, no ability to access the network key value stored in the radio’s non-volatile memory will be provided by the Host CPU’s serial interface protocol. The Host CPU will have no knowledge, nor access to, a radio network’s unique encryption key.

When the Coordinator intercepts the GTECH485 SYN protocol character it is to broadcast that packet to all radios in the PAN, to place any currently connected Peripherals in the OFF-line state. The Coordinator radio will inhibit any further communication with End Device radios by setting its connected radio address to NULL. The End Device radio’s Peripheral addressed by the broadcast SYN address packet will reply with the appropriate response packet. The Coordinator radio upon receiving a SYN response packet from an End Device radio will save that radio’s address as the new connected End Device radio address. The response packet from the addressed Peripheral is relayed back to the Host CPU. The End Device radio remains selected until another SYN protocol character is detected. All GTECH485 data packets seen by the Coordinator are relayed to the selected End Device radio and to the Peripherals on its local 485 bus. In the event the Coordinator is selected by the SYN address packet as the Peripheral, the Coordinator will broadcast the SYN Unlisten address to set all peripherals OFF-line.

The Texas Instruments stack TIMAC version 1.3.0 does not currently support security per the 802.15.4-2006 standard; however TI is promising to add this functionality to the stack in a future release.

This feature will not be supported by the radio firmware at this time. The entire GTECH485 data packet will be encrypted and encapsulated into the data payload section of the secure 802.15.4 packet. Using CCM* security and AES-128 bit key, the maximum safe data length for a single 802.15.4 packet ~80 bytes. The entire packet up to 80 bytes is encrypted/decrypted using the 802.15.4 standard security functions. Using the 802.15.4 Short Addressing option, additional bytes may become available for user data. TIMAC and the 802.15.4 standard do not directly support fragmentation of message streams of more than 80-bytes (secure packet). A higher-level network layer is required to fragment/defragment large messages. This may be performed by the Host CPU or the radio’s application layer. Fragmentation requires additional overhead with each 802.15.4 packet that will reduce the maximum packet payload length. 1234567 7+n+1 7+n+2Flags Seq. ShortDest. Addr. ShortSrc. Addr.

The currently selected End Device address in the Access Control List is the packet’s destination. Figure 14 - Single MAC Packet Exchange 5.5 FragmentedPacketsHost CPU packets greater than the maximum 802.15.4 payload capacity, it must be subdivided into smaller fragments. Fragmentation may be performed by either the Host CPU or the Radio module. The following fragmentation is for the proposed Radio module method. Serial data from the Host CPU to the Coordinator radio is buffered until the entire packet (up to 544-bytes) is received, before beginning the RF transfer. The radio does not begin the RF transfer as soon after 80 (or more) bytes have been received via the serial port as this would add complexity to the sequence if the transfer were to be truncated, or in error. By increasing the Host interface serial data rate to 230.4Kbps results in the serial latency being a relatively small percentage of the over-all packet transmission time. The End Device radio reassembles fragments into a buffer until the entire packet has been received, before sending it to the peripheral. Fragments must be sent and received in sequence; a fragment received out of sequence implies a lost
No. 96-1886-01E Rev. 1.1 GTECH Aircon Radio (Model GWT154) PAGE 29 OF 72 fragment, and the entire packet is discarded. To minimize the radio’s overhead, it does not issue a Negative Acknowledge (NAK) to the Host CPU, nor does it perform any clean-up of the un-sent packet fragments. The Host CPU needs to implement a failsafe timeout. After a packet timeout, the Host CPU may send a new packet to the Coordinator radio, overwriting the serial buffer and triggering a new RF transmission.

The Length/Index field in the fragmentation header has two functions depending on the state of the fragmentation flag bit. Host CPU serial packets requiring just one RF packet clear the fragmentation flag and the remaining 7-bit files is the absolute byte-count of the payload up to the maximum safe 802.15.4 encrypted packets payload size.
No. 96-1886-01E Rev. 1.1 GTECH Aircon Radio (Model GWT154) PAGE 30 OF 72 Fragmented packets have the fragmentation flag set and are sequenced using a range of index values above the maximum byte count of the secure 802.15.4 packet. An indexed fragment is assumed to hold the maximum number of payload bytes. The exception being the end packet in a fragment sequence where the fragmentation flag is set, but the Index/Length field contains a valid byte count for the remaining bytes of the packet. The maximum safe payload is derived from packets using extended addresses and PANs. Networks using short addressing have the option of reallocating the unused extended address bytes to the payload field. The fragmentation process described here uses the maximum safe payload length for its calculations. If a larger encrypted payload length is employed, the calculations need to be adjusted accordingly.

A reserved protocol character in the range between 0x0F and 0x1B could be used to indicate the start of a dedicated radio command packet. This protocol character would need to be reserved for radio configuration packets in all future versions of the GTECH485 protocol. A more transparent method is to exploit the zero-length fragment shown in Table 12 - Fragmentation Codes above. By definition, all radio configuration packets include a byte length as part of the header. A radio configuration packet’s checksum may be calculated and verified without knowing the received 802.14.5 packet’s absolute payload length.

The Terminal issues a specific address command to select the active Peripheral, all other Peripherals are to un-assert themselves from the bus. A reserved SYN (0x16) protocol character is used to identify an address command packet. Peripheral addresses are limited to a range between 0x21 and 0xFF. By default, if a peripheral receives an address packet with an address other than its own, it is to un-assert itself from the bus.

A special Un-Listen address (0x16) in the restricted range may be issued by the Host CPU to force all peripherals off-line. It is assumed the Un-Listen address does not receive an Address Response from any peripheral. The radio module should interpret Un-Listen as any address other than its own and forward it to the End Device radios. Packets receive from the Host CPU, after the Un-Listen address has been issued, should be discarded until another valid Peripheral address packet is received from the Host CPU and acknowledged by an End Device. The End Device radio will be required to act as a Terminal proxy whenever it receives a SYN address packet from the Coordinator. The End Device radio outputs the SYN packet on its local wired 485 bus, and then triggers a response acceptance period timer. Typically, a two-byte packet should be received by the End Device radio’s 485 bus with the first byte equaling the prior SYN packet’s address value. A successful response message is encapsulated in an RF packet and returned to the Coordinator radio. In the event of a timeout, or invalid response message, no RF response is issued. The Terminal Host CPU is expected to provide its own failsafe timeout.

The peripheral may detect the EOT to determine when it has received a complete message from the Host CPU, but will be required to implement a secondary failsafe timeout in the event the termination character is missed or corrupted. An idle period of more than 3.5 characters, since receiving the last character, will be inferred by the radio module to also indicate termination of a Host packet. The maximum payload length specified for a single GTECH485 Data Packet is 544 characters. This does not include header bytes, but includes any exception character insertions that have taken place.

The control character ESC (0x1B) is used as an escape prefix to signal that the following byte was in the range of the control characters and has been modified (1’s complemented) to place it outside the reserved range. All characters following the ESC are expected be in the range of 0x21 to 0xFF. In the event an ESC is followed by a reserved protocol character, special exception handling is required. The following example illustrates ESC insertion on a data packet with the string “Hello” as its payload. Process-ID, Carriage-Return, Line-Feed and Checksum characters all fall in the reserved range; they are 1’s complemented and prefixed with ESC before being transmitted. Other than being complemented as necessary, the Checksum is unchanged from the value calculated on the raw data. Figure 18 - Escape Character Insertion Referring to Error! Reference source not found., the UART receive process is reset to the idle state. The protocol characters ACK, NAK, CAN and SI are encapsulated and unicast to the currently connected radio. The protocol character SYN must be intercepted by the Coordinator radio to initiate a new peripheral address selection sequence. The Coordinator radio will clear any current connection’s address and broadcast the SYN address packet to all radios. Anytime the ESC protocol character is received on the 485 bus, the exception state is entered. Generally, the byte following ESC only needs to be inverted to restore it to its original value. It is documented in [2], the GTECH485 Bus Packet Protocol Specification, how a peripheral receiver is to respond in the event a protocol character does follow the ESC. ACK, NAC, CAN and SI are to be processes as if the ESC had not occurred, though the byte immediately following is to be inverted. A SYN address change will be processed normally, but any data received and buffered prior to that is discarded. Start of a new data packet ENQ discards any previously buffered data and starts over. The end of data packet EOT forwards the data packet to the connected radio, or processes locally if this radio is the selected peripheral.

The Radio should reply to all Host CPU data packets when it is the addressed peripheral. By definition, all Host CPU configuration packets requesting Parameters from the Radio are assigned even Command Code values (the Least Significant Bit (LSB) is cleared). Host CPU configuration packets writing Parameters to the Radio all have odd values (the LSB is set). Host CPU write configuration packets should receive a reply packet from the Radio with the same Command Code, zero Length and the Acknowledge bit set to one(1) if the Parameters were set as instructed, or zero(0) if something failed. Host CPU’s read configuration packets are sent to the Radio with zero Length. The Radio is to reply with the same Command Code, the correct Parameter Length and the Acknowledge bit set to one(1) if the requested parameters are in the Parameter field. If the requested parameters are not available, the Radio should reply with the same Command Code with the Acknowledge bit set to zero(0) and zero Length. Command packets with failed checksums, unknown Command codes, or of incorrect Length, will be ignored. The radio will not respond to failed command packets.

The following radio modes are initiated and indicated by the following: 8.1 UninstalledRadioAn un-commissioned radio from the factory defaults as an End Device that has not been joined to a PAN Coordinator. When initially powered the indicator LED may flash Red, then it will be extinguished. 8.2 EndDeviceJoiningPressing and holding the pushbutton switch on the radio for more than 3-seconds, but not more than 10-seconds will place the End Device radio into the network join mode. The radio will attempt to Associate with any nearby PAN Coordinators and indicates this by flashing the LED at a 500ms ON and 500ms OFF cadence. If and when, while attempting to Associate, the radio receives a beacon from a Coordinator in response to its beacon request, the LED will be steady ON indicating it has found a PAN Coordinator. If, after 30-seconds, the End Device radio does not successfully negotiate joining a network, the radio will abort the joining mode and turn the LED OFF. 8.3 RadioProgrammingThe GWT154 Wireless Transceiver is programmed using Texas Instruments’ CC-Debugger in-system-debugger/programmer for CC2530 and an adapter cable. Figure 20 – Custom Adapter Cable 8.4 AlternateConfigurationandSetupToolThe GTECH485 Test Tool is a PC application developed for a Windows platform. This tool can be used in manufacturing, compliance testing and by GTECH field engineers to configure and setup the radios. Specific information can be found in GTECH’s Field Service Training manuals.

Though not necessary for configuration, initialling requesting the radio’s status verifies communication has been successfully established and if the radio is factory-new or has been previously configured.  Select Coordinator Radio as the current 485 Peripheral  Get Status  Perform RSSI energy scan Once the RSSI scan has been initiated, the Terminal/Host must periodically poll the Coordinator for the scan results. Note: unless the Terminal/Host addresses another Peripheral on its wired 485 bus, the Coordinator’s Peripheral address only needs to be sent at the beginning of a configuration sequence.  Get RSSI results After the Terminal/User has selected a suitable channel, the radio may be configured.  Set Mode to Coordinator  Set Channel Mask and Default Channel  Set Mode to Start Network  Set Mode to Enable Joining Once the network has been started and is ready to accept new End Devices the Coordinator must be periodically polled to detect End Device associations.  Get ACL The Coordinator returns the entire contents of its Access Control List (ACL); this includes both new association requests and previously joined devices. New requests will have their security Key Index set to 1 (Factory Key used). The Terminal/Host may join a new End Device by responding to its associate request.  Join PAN The Coordinator radio will continue to accept new associated requests until the Terminal/Host disables it. If new devices have been accepted to the PAN the Terminal/Host should also instruct the Coordinator radio to save the updated ACL to persistent memory.  Set Stop Joining Mode  Set Mode to NV Save Optionally, the Terminal/Host may obtain the radio’s firmware version.
