3. Connect the RS-485 terminal block port on the first
VS-4x4YCxl
unit to
the RS-485 port on the second
VS-4x4YCxl
unit and so on, connecting
all the RS-485 ports.
4. Set the dipswitches, as section 5.5 describes. In particular:
Set the first
VS-4x4YCxl

15
VS-4x4YCxl
units as MACHINE # 2 to MACHINE # 16,
according to Table 4.
