2. Background The Names 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 Timers is a sole proprietorship created in February 2011
Proprietor: Walter Morgan
Engineer: Sandy Bumgarner

4. Printed Circuit Board Evolution
Version – 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

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

9. The front panel for IOTA-VTI is unchanged.
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 v3 now 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 format for IOTA-VTI v3
In “Transient” mode, an error is displayed for only 5 seconds

13. In “Persistent” mode errors 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 v3 production 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
