CU Link connection:
Up to 3 CUs can be cascaded (cascade CUs using the CU LINK
A/B terminals as shown below). Set one of the CUs as the primary
unit.
Since up to 100 DUs/INTs can be connected to each CU, if you
use 3 CUs, up to 300 DUs/INTs can be connected in total.
Follow the procedure below to cascade CUs.
①
Connect the CU LINK A terminal on the 1st extension CU to
the CU LINK B terminal on the primary CU.
②
When cascading 2 extension CUs, connect the CU LINK A
terminal on the 2nd extension CU to the CU LINK B terminal on
the 1st extension CU.

NOTICE
• When using only one CU without a CU Link connection,
be sure to set [CU Link Setting] to [Primary]. If [CU
Link Setting] is set to [Extension], we do not assume
responsibility for any unexpected consequences that may
occur.
• Up to 6 INTs can be connected to the primary CU. They
cannot be connected to extension CUs.

Attach the bottom cover to the DU/INT.
After connecting the Ethernet cables to the DUs/INTs, attach the
bottom cover to each DU/INT.
• The Ethernet cable is fixed securely between the DU/INT and
the bottom cover. This helps reduce the load that the DU/INT
places on the Ethernet cables.
• To lead the cable out to the rear side, use the through hole

Attach the optional bottom weight to the DUs/INTs.
• When using DUs/INTs that are not secured to desktops
or tabletops, it is recommended to use the optional
bottom weight (330g) for secure placement.

team.
