Filter valid settings are 1 to 8. The filter settings are used to help prevent dirty track from affecting
loco operation by rejecting commands that do not repeat for the selected count within a short
period of time. For example, if the loco is on speed step 20 and the user sets speed step 30, the
default filter setting of 2 requires 2 speed step 30 commands to change to speed step 30. Normally
commands are repeated often enough in DCC controllers to pass the default filter settings select-
ed. For example: If your loco stops occasionally, increase the filter setting for CV59 and CV60; if
the loco does not respond to all speed commands, decrease the filter setting for CV59 and CV60.
