  1. IOTA-VTI Status Report - 2015 Walter V Morgan Video Timers Presented October 16, 2015 at the 2015 IOTA Annual Meeting University of Southern Nevada Cheyenne campus, North Las Vegas, NV

  2. Background • IOTA owns the rights to IOTA-VTI • Video Timers manufactures and distributes under an exclusive license • Video Timers pays IOTA a royalty The Names Oversight of IOTA’s interests is vested in a Steering Committee consisting of: Originators: Tony Barry & Dave Gault (Australia) IOTA Officers: Steve Preston & Chad Ellington Appointed: Paul Maley

  3. Video Timersis a sole proprietorshipcreated in February 2011 Proprietor: Walter Morgan Engineer: Sandy Bumgarner

  4. Printed Circuit Board Evolution • Version 1.1.9 – July 2011 to Jan 2012 • Version 2.2 – from March 2012 Reduced power requirement; fuse added; video titler to mother board; external GPS added • Versions 2.4, 2.6 –2012 Spare fuse added • Software version 45 – from Jan 2013 Blanks HH:MM:SS for 3 seconds • Version 2.9 – from Sept 2013 • Version 2.10 – from March 2014

  5. Inside the IOTA-VTI ver. 2.10A custom printed circuit board is used for the IOTA-VTI “Arduino” board Internal GPS

  6. A show-stopper, March 2014 • GlobalSat 406A GPS discontinued: - “drop-in replacement” was unsatisfactory - v 2.10 production limited by GPS available • Added complication: - “Arduino board” quality poor, high rejection rate

  7. Resolution of GPS problem • Shift to a new generation GPS: GlobalTop’s PA6H • Re-design printed circuit board • Re-write software The Result:IOTA-VTI v3 Last v 2.10 sales: Oct 2014 First v3 sales: March 2015

  8. Inside the IOTA-VTI v3ver. 3.8 PCB, mounted, with end panels Microprocessor PA6H GPS Li-ion cell

  9. Outside the IOTA-VTI Versions 1 and 2 Version 3 The front panel for IOTA-VTI is unchanged. The back panel: USB port removed; Dark switch added; external antenna and serial dongle connectors added.

  10. Splash Screen for IOTA-VTI v3now shows battery status

  11. Position screen for IOTA-VTI v3 “Persistent” error mode has been selected The alternative error mode is “Transient” (Selection is via an internal DIP switch)

  12. The error notification display formatfor IOTA-VTI v3 In “Transient” mode, an error is displayed for only 5 seconds

  13. In “Persistent” modeerrors will continue to be displayed The errors in this experiment were produced by introducing and removing massive shielding “Persistent” mode allows low error rate to be confirmed. IOTA-VTI v3 is delivered set for “Transient” mode.

  14. IOTA-VTI v3production life expectancy • MAX7456 video titling IC has been in “end-of-life” status for 3 years Opportunity to place a “last order” is expected • PA6H GPS firmware status is not guaranteed Significant software revision might be required
