4.1.2 Ethernet Link Parameters
Parameter group EN-1# holds information Ethernet Link
information:
Please note the Ethernet Link Parameters are unique per
port.
EN-10 Link Status and EN-11 Link Duration displays
information on the link status, per port.
EN-10 Link Status will display Link or No Link according to
the status of the present port.
EN-11 Link Duration will display the duration of the link on
the present port. If the link is broken the counter will be
reset.
EN-12 Auto Negotiation - is a feature that enables two
connected Ethernet devices to choose common
transmission parameters, such as speed and duplex mode.
In this process, the connected devices first share their
capabilities as for these parameters and then choose the
fastest transmission mode they both support.
Incapability between the connected devices, may lead to
decreased communication performance.
To prevent this, Auto Negotiation can be disabled.
If EN-12 Auto Negotiation is set to OFF, link speed and
duplex mode can be configured manually in EN-13 Link
Speed and EN-12 Auto Negotiation.
EN-13 Link Speed - displays/sets the link speed per port.
“None” is displayed if no link is present.
EN-14 Link Duplex - displays/sets the duplex mode per port.
Half-duplex provides communication in both directions,
but only in one direction at a time (not simultaneously).
Full-duplex allows communication in both directions, and
unlike half-duplex, allows for this to happen simulta-
neously.
