Par. 12-03,
Default Gateway
is optional and only used in routed networks.
Par. 12-06,
Name Servers
Par. 12-07,
Domain Name
Par. 12-08,
Host Name
Are used with Domain Name Server systems and are all optional. If DHCP or BOOTP is selected as IP address assignment, these parameters are read
only.
NB!
It is only possible to assign valid class A, B and C IP address to the option. The valid ranges are shown in the below table:
Class A
1.0.0.1 - 126.255.255.254
Class B
128.1.0.1 - 191.255.255.254
Class C
192.0.1.1 - 223.255.254.254
4.1.2 Ethernet Link Parameters
Parameter group 12-1* holds information Ethernet Link information:
12-10
Link Status
12-11
Link Duration
12-12
Auto Negotiation
12-13
Link Speed
12-14
Link Duplex
Please note the Ethernet Link Parameters are unique per port.
Par. 12-10,
Link Status
and par. 12-11,
Link Duration
displays information on the link status, per port.
Par. 12-10,
Link Status
will display Link or No Link according to the status of the present port.
Par. 12-11,
Link Duration
will display the duration of the link on the present port. If the link is broken the counter will be reset.
Par. 12-12,
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.
By default this function is enabled.
Incapability between the connected devices, may lead to decreased communication performance.
To prevent this, Auto Negotiation can be disabled.
If par. 12-12 is set to OFF, link speed and duplex mode can be configured manually in par. 12-13 and 12-14.
Par. 12-13,
Link Speed
– displays/sets the link speed per port. “None” is displayed if no link is present.
Par. 12-14,
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 simultaneously.
