FDX Flow Ctrl 
This setting enables or disables flow control for the port when the port’s Speed is set to Auto. The 
final result will be determined by the Auto process between the Weidmüller switch and connected 
devices. 
Setting 
Description 
Factory 
Default 
Enable 
Enables flow control for this port when the 
port’s Speed is set to Auto. 
Disabled 
Disable 
Disables flow control for this port when the 
port’s Speed is set to Auto. 
MDI/MDIX 
Setting 
Description 
Factory 
Default 
Auto 
Allows the port to auto-detect the port type of 
the connected Ethernet device and change the 
port type accordingly. 
Auto 
MDI 
Choose MDI or MDIX if the connected Ethernet 
device has trouble auto-negotiating for port 
type. 
MDIX 
Note about Auto-Negotiation (possible lost of data packages in case of “Duplex 
mismatching”) 
If an active AutoNeg-Port of the Switch is connected to a non-negotiating device, then the 
Switch will set its port transmission speed same as the connected device but is unable to 
correctly detect the duplex mode. As result the AutoNeg-port is set to the correct speed 
but is using always the half duplex mode as required by the IEEE 802.3u standard in such 
cases. For correct transmission between an AutoNeg-Port and a non-negotiating port the 
port with fixed values has to be set to half-duplex mode (speed either 10 or 100 Mbit/s). 
3.1.5 Network Parameters 
Network configuration allows users to configure both IPv4 and IPv6 parameters for management 
access over the network. The Weidmüller switch supports both IPv4 and IPv6, and can be managed 
through either of these address types.
