Connections to other switches can use half or full duplex; connections to hubs are possible

only in half duplex mode.

Transmission medium

Data transmission at 10 Mbps and at 100 Mbps is over two wire pairs (pin 1, 2, 3, 6) of the

twisted pair cable. For 10 Mbps, at least a category 3 (Cat 3) and for 100 Mbps, at least a

four-wire (2x2) category 5 (Cat 5) cable is necessary.

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.
