Connecting the data lines
You can connect terminal devices and other segments on the ports of the device via
twisted pair cables or F/O cables.
Install the data lines according to your requirements.
10/100 Mbit/s twisted pair connection
10/100 Mbit/s ports (RJ45 socket) enable the connection of terminal devices or
independent network segments according to the IEEE 802.3 100BASE-TX and
10BASE-T standard.
These ports support:
Autonegotiation
Autopolarity
Autocrossing (if autonegotiation is activated)
100 Mbit/s half-duplex mode, 100 Mbit/s full duplex mode
10 Mbit/s half-duplex mode, 10 Mbit/s full duplex mode
Delivery state: autonegotiation activated
The socket housing is electrically connected to the rear panel.
Pin assignment of the RJ45 socket:
One line pair: pin 3 and pin 6
One line pair: pin 1 and pin 2
Remaining pins: not used.
