Auto MDI/MDI-X Connection 

The Auto MDI/MDI-X function allows users to connect EDS-208’s 
10/100BaseTX ports to any kind of Ethernet device, regardless of how the 
Ethernet cable is wired. This means that you can use either a

 straight-through

 

cable or 

cross-over

 cable to connect EDS-208 to Ethernet devices. 

 

Dual Speed Functionality and 
Switching 

EDS208’s 10/100 Mbps switched RJ45 port auto negotiates with the connected 
device for the fastest data transmission rate supported by both devices. All 
models of EDS-208 are plug-and-play devices, so that software configuration 
is not required at installation, or during maintenance. The half/full duplex 
mode for the switched RJ45 ports is user dependent and changes (by 
auto-negotiation) to full or half duplex, depending on which transmission speed 
is supported by the attached device.
