Also you can change Transport stream ID and Original network ID, see Figure 17. Each stream in a network must have
unique ID, called „Transport stream ID“. An Original_Network_ID is defined as the “unique identifier of a network”. It can be
linked to NetworkID, or used value from this location:

In case of transparent mode, Fields in Figure 18 will not be used! These values will be the same as in input transport
stream. Also all services will enabled (Column „Enable“ will be greyed in Figure 13).
NOTE
: If Transport stream ID or Original Network ID is changed (from original ones), the EIT/EPG will not be available,
because EIT is not regenerated!
Very important part in this page is the 2nd table, where other streams in the network can be described (see Figure 18).
Figure 18. Streams in network
Every channel in the network must be described in NIT. Otherwise TV automatic channel tuning function will not find all
channels. So, if there are more modulators in the network, all channels must be included in this table. If there are more
devices manufactured by Terra, which are controlled via Ethernet, all broadcast information can be captured automatically
by adding its IP address and pressing „Load“ button. In case if the frequency was added manually already, that record will
be updated. Otherwise, a new record will be inserted.
7.4. IP settings
This screen (Figure 19) consists of three tables: "Control interface IP parameters", "Time parameters" and "IP status".
The IP parameters tables are used to configure Ethernet connection parameters. In the "Time parameters" table a local time
offset can be set. In the "IP status" table current status of Ethernet interface is displayed.
Figure 19. IP settings screen
The description of the "IP parameters”
"MAC Address" - the physical address of the module's Ethernet network card is displayed automatically.
"IP Address" - enter the IP address that you wish to assign to the module. This address must fall within the range of local
network addresses.
"Subnet mask" - enter the local network mask.
"Gateway" - enter the IP address of this gateway. This information is only required if you want to access the module from
the Internet.
7.5. CAM settings
This screen consists of three tables: "CA module monitor", "CA module information" and "CA module menu". In the "CA
module monitor" table CAM restart function in case of descrambling error can be enabled. It is recommended to turn off this
option if inactivated conditional access card has been inserted.
The content of the remaining tables depends on the inserted CA module.
