2Purpose Purpose Target Usage Technical Advantage Uniqueness A gateway between a products data bus and a PC.Target UsageProduct developmentProduct testingManufacturing testingTechnical AdvantageAssists in data bus developmentProduct diagnosticsAutomated testingNode (peripheral) emulationAssembly line testingNon-standard messaging (intentional errors)UniquenessHigh speed processor (can emulate hardware peripherals in software)Flash programmable firmware (allows user to easily update/change firmware)Very low cost
3Overview DEMON Gateway Replacement Utilizes Ubicom (Scenix) 52-pin uP running at 50MHzRS232 & USB InterfacesHardware capable of monitoring:CAN (High Speed & Low Speed 2-Wire)GMLAN (Single-Wire CAN)J1850 (Class 2)Keyword 71 and 82High Speed IICIDB-C (Connect as Node or Monitor)SPI (Connect as Controller or Monitor)Ford ACP (requires additional hardware)J1708 (requires additional hardware)BEAN (requires additional hardware)Other buses with help of stackable daughter boardFlash ProgrammableUses SX Blitz (future through USB)Firmware updates are available on the WEB (internal and external)
4Hardware Board size 5.175” by 3.0” Onboard bus support for Class2, CAN, and KeywordCapable of handling custom daughter boards for additional communication busesAssembled and packaged by CSI Electronics in Kokomo
6Software Firmware Bus Monitor SAINT Monitor Plugins Palm Applications Unlimited Firmware updates available on the webFlash Firmware using the SX Blitz via the serial portBus MonitorEasy to use Windows interfaceSupports decode, short, and raw data message displaysAbility to send group and periodic message filesUtilizes data filtering and emulationSAINT Monitor PluginsIntegrates custom programs into the SAINT MonitorReduces the need for an additional com portExample Plugins include C2 Memory Editor and Arbitrary Text CreatorPalm ApplicationsCompatible with Palm OS Version 3.5 and higherExample applications include C2 Memory Editor, DTC reader, and Palm SAINT Monitor
12Future Direction USB Daughter Boards Hardware Revision 2.0 Integration of a USB daughter board is in progress. This will prevent having 2 different version of the SAINT board (serial and USB) along with keeping the cost low.Daughter BoardsThere are currently 2 daughter boards developed. One board supports 2 BEAN communication buses and the other supports J1708/ACP and E&C (still under software development) communication protocols.Hardware Revision 2.0Enhancements to Rev 2.0 will include the addition of a new Ubicom (formerly Scenix) processor. This new processor will have a much larger memory size, USB capabilities, operate up to 100MHz, and much more. Plans also include have 2 CAN controllers with 2 transceivers for each type of CAN bus. This will require the implementation of a MUX to switch various I/O lines via software.Known ConcernsOur biggest concern is the 9-pin power connector which limits the amount of busses brought out via banana plugs.Class 2 FlashHardware Revision 1.2 added an 8K FRAM IC that will allow the support of up to 8K block transfers. The firmware and SAINT Monitor Plugin are currently being developed to support this feature.
