2.2 Cabling
ET-adapter is connected to the network adapter with a direct Ethernet cable.
The maximum length of a category 5 cable is 100m. If the ET-adapter is
connected to the Ethernet hub or switch then use a cross-connected Ethernet
cable.
Figure 11. Direct cabling
Ensure that the Ethernet port that is connected to ET-adapter has the same
configuration as the ET-adapter. Port speed and duplex status have to be the
same at both Ethernet ports. It is not recommended to use auto-negotiation
option. Port configuration should always be fixed.
