AVT 200HD Tuner • HTML Configuration and Control 78
IP Settings Fields
The IP Settings fields provide a location for viewing and editing settings unique to the
Ethernet interface. After editing any of the settings on this page, click the Submit button at
the bottom of the IP Settings section.
Unit Name field
The Unit Name field contains the name used as the “from” information when the AVT
e-mails notification of its failed or repaired status. You can change this name field to any
valid name, up to 24 alphanumeric characters.
DHCP radio buttons
The DHCP On radio button directs the tuner to ignore any entered IP addresses and to obtain
its IP address from a Dynamic Host Configuration Protocol (DHCP) server (if the network is
DHCP capable).
The DHCP Off radio button turns DHCP off.
Contact your local system administrator for this setting.
IP Address field
The IP Address field contains the IP address of the connected AVT. This address is encoded
in the tuner flash memory.
Valid IP addresses consist of four one-, two-, or three-digit numeric sub-fields separated
by periods. Each field can be numbered from 000 through 255. Leading zeros, up to three
digits total per field, are optional. Values of 256 and above are invalid.
The factory-installed default address is 192.168.254.254, but if this conflicts with other
equipment at your installation, you can change the IP address to any valid value.
NOTE: IP address changes can cause conflicts with other equipment. Only local system
administrators should change IP addresses.
Gateway IP Address field
The Gateway IP Address field identifies the address of the gateway (to the mail server) to
be used if the tuner and the mail server are not on the same subnet.
The gateway IP address has the same validity rules as the system IP address (see “IP Address
field,” above).
Subnet Mask field
The Subnet Mask field is used to determine whether the tuner is on the same subnet as the
mail server when you are using a subnet (see “Subnetting — A Primer” under “Ethernet
Connection” in the “Reference Information” section for more information).
The subnet mask address has the same validity rules as the system IP and gateway IP
addresses.
MAC Address field
The MAC (media access control) address is a unique hardware address by which each
individual AVT can be identified. It consists of six pairs of characters separated by hyphens.
For all Extron products, the first three character pairs are 00-05-A6, followed by three more
pairs unique to the individual device. The MAC address is hard coded in the tuner and
cannot be changed.
