Network Traffic
This can be used to change the network speed for your server. Normally, there is no need to
use anything other than Auto-negotiate, which will automatically select the correct media
type. However, if you are using a switch or similar device on your network and need to
specify the media type, then this can be done by selecting the correct type from the
drop-down list.
SMTP (email) Network Settings
The AXIS 250S can be configured to send event and error email messages to predefined
addresses.
Primary mail server - Enter the name or IP address of the server providing your mail facilities.
Note that to use a host name, a DNS server must be specified in the TCP/IP network
settings.
Secondary mail server - Enter the name or IP address of a secondary mail server. This will be
used if the primary mail server is unavailable.
Send test email to - test the setup by clicking the Send button.
Ports & Devices
IO Ports
This page allows you to enable and configure the four inputs and one output supported by
the server. Ports can be enabled or disabled, given descriptive names, and their Normal
state can be configured.
The normal state describes the inactive state for the port. It is also an indication of the
function of the connected equipment and how it is activated. For example, if the activation
circuit in a door switch connected to an input is normally closed, this means that as long as
the door is closed then the state is also closed (inactive). When the door is opened the door
sensor will be active and the input will no longer be in its normal state. This is how events
based on external equipment are triggered.
Thus, in the I/O port list, if the Normal state for an input is set as Open, but the Current
state is shown as Closed, then the port has been activated, and vice versa.
Important!
Please note that some external devices may behave incorrectly in the event of an error
condition, e.g. a power cut.
