Ethernet connection (rear of device)
The Ethernet interface can be used to integrate the device via a hub or switch into a PC
network (TCP/ IP Ethernet). A standard patch cable (e.g. CAT5E) can be used for the
connection. Using DHCP, the device can be fully integrated into an existing network
without the need for additional configuration. The device can be accessed from every PC in
the network.
• Standard: 10/100 Base T/TX (IEEE 802.3)
• Socket: RJ-45
• Max. cable length: 100 m
• Galvanic isolation; testing voltage: 500 V
