Transmission range
The maximum transmission range (segment length) is 100 m.
Connectors
The connectors used are 8-pin RJ-45 jacks with securing collars. The securing collar in
conjunction with the cover ensures a flush fit and the locking mechanism with the
PROFINET-compliant male connectors IE FC RJ-45 Plug 180 and IE FC_RJ-45 Plug 145
provides a rugged node attachment suitable for an industrial environment that provides strain
and bending relief for the RJ-45 jack.

Transmission rate
The transmission rate of the electrical gigabit ports is 1 Gbps.
Transmission mode
The transmission mode for 1000Base-T is specified in the IEEE 802.3ab standard.
At 1 Gbps, autonegotiation is optional.
Two communication modes are possible:
●
Half duplex
●
Full duplex

Data is transmitted over an eight-wire twisted pair cable.
Note
For data transmission at 1 Gbps, at least a Cat 5e twisted-pair cable with 4 x 2 wires is
necessary. With a four-wire cable (2 x 2 wires), a maximum data transmission rate of 100
Mbps is possible.
Transmission range
The maximum transmission range (segment length) is 100 m.
