  1. RTDL System Heather Hartmann (BNL) SNS Global Controls SNS Software Final Design Review

  2. Features • Provides access to Machine Parameters • Central Location • Contained in one Chassis • Broadcast to all locations • 10MHz serial differential PECL SNS Software Final Design Review

  3. V105S • Inputs: • Transmit Trigger • Single ended TTL - 50 ohm • Outputs: • 10MHz encoded clock transformer coupled • Differential PECL SNS Software Final Design Review

  4. Features • VMEbus based • A16, D16, D08(OE) • Address jumper selectable on 512 byte boundary • Interrupts supported • Level and Vector configurable • NOREPLY Interrupt • Time division multiplexes machine parameters onto the link • Supports up to 16 V206 modules (128 parameters) SNS Software Final Design Review

  5. V105S Registers • Command (16 bit) • Reset • External Trigger ON/OFF • Go (Init Done) • Interrupt Enable • Interrupt Level • Default Configuration • Not Reset, External Trigger OFF, Init Not done, Interrupts DISABLED, Interrupt Level 0. SNS Software Final Design Review

  6. V105S Registers (con’t) • Status (16 bit) • No Reply Error • Init Done Error • RTDL ACTive • No Reply ID Code • Parameter ID Code Scan List • Lists Input Modules’ Codes • Terminates with Code 00 SNS Software Final Design Review

  7. V105S - Encoder Block Diagram Parameter Data (24 bits) Local Bus Interface RTDL Encoder Parameter Data (24 bits) RTDL Link Data Ack Strobe Input Module Interface Parameter ID (8 bits) Parameter ID Strobe Load Data Encode Trigger VMEbus Interface and Control Parameter ID (8 bits) Scan List RAM VMEbus Parameter ID Address (8 bits) External Trigger Event SNS Software Final Design Review

  8. V206 • Inputs: • External Data (8) • 5Mbit bi-phase mark encoded clock • Differential Transformer coupled TTL • Outputs: • to V105S via P2 connector (local bus) SNS Software Final Design Review

  9. Features • VMEbus based • A16, D16, D08(OE) • Address jumper selectable on 512 byte boundary • Interrupts supported • Level and Vector configurable • Link Interrupts only • 8 identical input channels • Loaded from VMEbus • Loaded from external source SNS Software Final Design Review

  10. V206 Registers: Module Configuration • Command • Module Enable • Interrupt Level • Interrupt Enable • 1 bit per channel • Interrupt Status • 1 bit per channel - pending interrupt • Interrupt Vector SNS Software Final Design Review

  11. V206 Registers: Channel Configuration • Command • 8 bit Parameter ID • Channel Enable • Halt/Load VME Data • Required due to 16 bit VME Data • Internal/External Mode • Reset SNS Software Final Design Review

  12. V206 Registers: Channel Status • Status • 8 bit Serial link ID Code • Frame Error • CRC Error • Link Status • Interrupt Source • Interrupt Status SNS Software Final Design Review

  13. V206 Registers: Channel Data • Internal Data Register (VME - 24 bit) • 1 per channel • External Data Register (24 bit) • 1 per channel SNS Software Final Design Review
