[time-nuts] KS-24361 Lady Heather problem

Mon Jun 18 19:29:36 UTC 2018

I have two copies running on windows, each with separate config files, each running to separate sub rs422 adapters.  I don’t have them running from separate directories but you might want to try that.  Setup two complete copies with separate directories, config files, etc.
Regards,

Jerry
