Larry,
Thanks for you suggestions. While the sequence looks like the power up
sequence is it slower by about 2x. Also it doesn't start until I select
"Connect" in otwincfg. I've also verified that the power is good. In otwincfg
when I check "Erase device and load new firmware" and then select "Connect"
nothing other than the periodic LED sequence I've already described occurs, so
no success trying to load new firmware.
Thanks again

see that option on the Tracker Connection window. Just check the box and follow
the instructions after selecting 'Connect".
