7. Operating

7.1 Initial conguration

All modules leave the factory with this control Ethernet interface IP address: 192.168.1.10. In order to avoid conicts with
other IP addresses, it is necessary to perform an initial conguration in local mode. Subsequently, it will be possible to access
the modules via the local area network (LAN), either to re-programme it or to check is operating status.

The modules leave the factory with the following Control Ethernet interface TCP/IP conguration:

IP address of the module: 192.168.1.10

Subnet mask: 255.255.255.0

Default Gateway: 192.168.1.1

To access each module, use a PC or MAC personal computer equipped with an Ethernet

card and RJ-45 cable (CAT-5E or CAT-6). The IP address of the PC/MAC must be congured
within the following range: 192.168.1.2 - 192.168.1.254 (do not use 192.168.1.10, since this is
the IP address of the module to be congured). To start the conguration of the module, open

your web browser and type in the following direction: http://192.168.1.10. The login prompt
will appear on the screen (see Figure 6.). Module can be controlled using any web browser.
The exception is Internet Explorer, which must be 10.0 version or higher.

7.4. Output settings

Figure 11. "Output settings "

This screen consists of two tables: "Streaming settings" and "SAP/SDP settings". The "Streaming settings" table is

used specify common streaming parameters to all output streams. The "SAP/SDP settings" table is used to congure the

announcement and service description SAP/SDP channel.

7.4.1. Streaming settings table

This table is used specify common streaming parameters to all output streams.
This table consists of following lines:
"Protocol" - the drop down menu offers two options: UDP and RTP/UDP. UDP is a transport protocol which is not connection

oriented and is particularly useful for streaming. RTP/UDP adds extra data elds so that the data ow is served at the correct

speed for its projection in real time.

"TS packet count" - count of the MPEG2 TS packets in the UDP packet. Can be selected from one to seven. It is

recommended to select the value of seven packets.

"Time To Live" - a parameter used to restrict the stream multicasting range. A number between 1 and 255 is entered in

this box. Each time that an IP stream passes through a router, the TTL is reduced by one unit. The stream will be rejected
by any router when the TTL value is reduced to zero.

"QoS" - quality of Service. The drop down list offers ve differentiated service options or Diffserv. These options relate

to the priority that you wish to assign to the streaming packets on their routes through switches or routers that are QoS

management capable.

QoS values:
1 - Top priority

2 - High priority video

3 - Low priority video

4 - Video and voice

5 - Best effort (best effort made to correctly deliver the video data and the associated audio data)
"Count of output streams" - count of output streams, displayed in the "Output streams" table bellow. Can be selected

from one to twenty ve. After updating ot the FR input parameters this count is automatically set to input stream count value.

"Send IGMP query messages" - enable of the IGMP query messages transmitting. Enable this function when the streaming
output of module is connected to the manageable Ethernet switch with IGMP snooping support. In order for IGMP snooping to
function, a multicast router must exist on the network and generate IGMP queries. The tables created for snooping are associated
with the querier. Without a querier the tables are not created and snooping will not work. When the IGMP query messages send

enabled, the module acts as the multicast router. It is sufcient to enable the IGMP query in one module per one Ethernet switch.

Once the different data values have been entered, click on "Update" to conclude the streaming settings.

7.4.2. SAP/SDP settings table

This table is used to congure the announcement and service description SAP/SDP channel. SAP and SDP are two

protocols for creating an EPG type program guide.

"Enable" - check the box if you wish to transmit the service information by SAP/SDP protocol.

"Sending period" - introduce the time interval, in seconds, at which the transmitted information will refresh.

"Username" - the name entered will be transmitted on the SAP/SDP channel.

"IP address" - multicast address of SAP/SDP messages. It is need to be changed only when your IP receiving equipment
use different address.

7.5. IP parameters

This screen (Figure 12) consists of four tables: "Control interface IP parameters", "Streaming interface IP parameters", “SNMP
settings”, “E-mail settings”. The IP parameters tables are used to congure Ethernet connection parameters of both interfaces.

Figure 12. IP settings screen

7.5.1. Control and streaming interfaces IP parameters

The description of the "IP parameters" tables rows.

"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
