4.7 Connections
4.7.1 Ethernet interfaces (Port1 - Port4)
Every Ethernet interface detects automatically whether the connected counterpart works as
transmission or network termination device. This way both normal and crossover cables can
be used (MDI/MDI-X).
The Ethernet interface can operate at transmission rates of 10 or 100 Mbps, depending on the
connected devices in half duplex or full duplex mode. The operation mode is detected and set
automatically by the EDS500 devices. A manual configuration is possible.
