When connecting more than one
VS-44HC
unit, set a different machine # on
each unit. You do not have to number the units in the sequence order as they
connect to the PC, but it is essential that each unit is assigned a unique
machine number.
1 Do not set both DIP 6 and DIP 7 ON
2 When using a single unit, set the unit to MACHINE # 1
