RJ45 interfaces ("Ethernet") 6- ETH_RJ45-Schnittstellen ("Ethernet")_Switch
Two free switch ports are provided as Ethernet interfaces via an internal
autosensing switch. The autosensing switch automatically detects
whether data transfer is occurring at 10 Mbit/s or 100 Mbit/s.
The switch's automatic crossover function means there is no need to
distinguish on the connection cable between patch cable (uncrossed
data line connection) and crossover cable (crossover data line connec-
tion). The switch automatically creates the correct data line connection
internally. It is therefore possible to use patch cable as the connection
cable for both end devices and cascading.
Both Ethernet interfaces use RJ45 technology.
6.3.2 Requirements of the connection cable and connector
Requirements of the connection cable and connector 6- ETH_Anforderungen an das Verbindungskabel und den Stecker
The following minimum requirements must be met:
` Ethernet standards (min. Category 5) 10BaseT or 100BaseTX
` Double-shielded twisted pair cable for industrial Ethernet use
` Shielded RJ45 connectors (industrial connectors)
