A crossed twisted-pair cable (10BASE-T) can be used to make a direct connection between the
S10mini and MELSEC. The maximum permissible cable length for such a connection is 100 m.

When a hub (multiport repeater) is connected to a transceiver via a transceiver cable (AUI cable),
the S10mini connected to the hub is connected to the MELSEC that is connected to the
transceiver.
When connecting a station to the hub, use a straight twisted-pair cable (10BASE-T).

If the distance between the S10mini or S10V and MELSEC is short, the S10mini or S10V and
MELSEC can be connected to a hub with a straight twisted-pair cable (10BASE-T) without
having to use a coaxial cable or transceiver.
