2.2. RJ45 connector pin layout
The EtherCAT
®
unit is equipped with two shielded RJ45 connectors. When you use
VF-MB1, the shielding is connected to the drive ground. When you use VF-S15, the
shielding is connected to the grounding terminal of option adapter.
Use an STP (shielded twisted pair) Ethernet cable.
The transmission speed is detected automatically by the card (10 Mbps or 100 Mbps).
The card can operate in half duplex or full duplex mode, whether connected to a hub or a
switch and regardless of the transmission speed (10 Mbps or 100 Mbps).
