This section gives you the ability to customize select features of the COM51 cards to better suit your
application.
Change IP settings the card
Control and configure Syslog server
Enter IP address of NTSC-8 and Tuner Count
Following is a brief explanation of each field shown above:
This field allows for one of 3 methods of IP address assignments to be chosen.
0 = Default - In this mode the IP address is assigned to the card based on the chassis ID and slot the
card is currently in. The formula for this address is 192.168.3.[1 + (chassis ID X 16) + slot number].
In the default IP mode, the Base_IP and the Gateway fields are ignored. The Subnet field is also
ignored but the Subnet mask is set to 255.255.0.0 and is applied.
1 = DHCP_Persistent - In this mode all IP address information Base_IP, Subnet and Gateway are
taken from the DHCP lease that the DHCP server issues to the card and is stored in non-volatile
memory.
4 = Fixed - In this mode the user sets the Base_IP, Subnet and Gateway fields. All fields MUST be set.
A Gateway MUST be defined regardless of it being there or not for this mode. Once you set the card
IP you must reboot the card.
8 = No Change - This setting does not actually represent a separate mode, but rather acts to tell the
COM51 card to continue whatever mode it is currently using.
In the Default mode this field will display the IP address of the card. In the DHCP_Persistent mode
this field will display the last address stored in non-volatile memory. In the Fixed mode this field is
where you would enter the IP address you wish to assign to that card.
This field allows you to give a subnet mask of your choosing to the COM51 card.
This field is only applied in the Fixed mode.
This field allows you to set a default gateway of your choosing for the COM51 card.
This field is only applied in the Fixed mode and must be set when using that mode.
Time to Live field in IP protocol header.
This field allows you to direct the COM51 card to send its log files to an external destination
automatically. (See section 18 Syslog Server Setup)
This is especially useful for monitoring the health of the system over an extended period.
After entering the IP address of the destination, the log files will start being forwarded to this
address after a short delay.
You may then run a system-logging utility like TFTP32 on the destination computer to capture this
information. Once the Log IP is set you must reboot the card.
This field allows you to define the level of detail that will be captured in the resulting log files.
Due to the complexity of this setting, it is strongly advised that it be left blank unless someone from
support has asked to change the value.
