Connect the SX-2000CI and SX-2000CO to the SX-2000AO or SX-2100AO in cascade as shown below. The
connection order of the SX-2000CI and SX-2000CO can be changed.
Set the CI/CO link through switch of the device directly connected to the SX-2000AO or SX-2100AO to ON, and
that of the second cascade-connected device to OFF.
Notes
• Total cable length connecting CI/CO link terminals within the system must be kept shorter than 800 m.
• The figure shows an example when the SX-2000CI is directly connected to the SX-2100AO.
