E125 Auto Pilot Controls do not work after upgrade to 15.59

[lwitty]

Chuck -

I left a number through PM as requested, would like to discuss this issue.

As an update, I was able to acquire another SeaTalk converter with 1.21 software and have installed it. The pilot controls are now working as they did prior to the LH & converter software upgrade.

Couple of questions:
1) Will running latest version of LH and older version of SeaTalk converter software create any other issues I should be aware of? Also, will future LH upgrades attempt to update the converter as well?
2) I can make the upgraded converter available to Raymarine to investigate further if this will help in a longer-term resolution.

Thanks - Larry
