(2) Connecting to 10BASE-T
The following procedure assumes that UTP cable (10BASE-T twisted-pair cable) is
already setup. In the case of 10BASE-T, note the direction of the UTP cable connector
and insert in the modular connector (10BASE-T).
FL312 is designed exclusively for 10 Mbps Ethernet. Use 10 Mbps HUB if using the 10BASE-T side.
If a 10M/100M switching HUB must be used, use a HUB that can fix the port transmission speed to 10
Mbps.

About the ferrite core of the transmission cable

10BASE-T cable.
