11.1 Ethernet
All device versions are Ethernet-capable via an RJ45 interface. The devices support
10/100 Mbit full/half duplex. It is recommended to use at least Cat.5 cables (EIA/TIA-568)
for installation.
11.1.1 IP addressing
The EMpro devices can be assigned both a static and a dynamic IP configuration.
Current devices support IPv4.
In the delivery state, the devices use a static IP configuration with the following parameters:
The entry IP 0.0.0.0, e.g., for the default gateway, indicates that no default gateway has
been configured.
When the dynamic IP assignment is used, the device receives its IP configuration via the
DHCP protocol from another DHCP server in the same network.
