With TreeTech 3.1, the serial connection to a GCM-86000 is not working.

Product Line

TAC I/A Series

Environment

TreeTech 3.1

Cause

Using TreeTech to do GCM backups with the demise of ProBlock

Resolution

On page 25 of the TreeTech Engineering Guide (F-26640), the recommended setting for ODSR (output date set ready) is ON for a GCM-86000.

At times, the age and model of laptop may require that ODSR be set to OFF.  Try it.
