2.4.2 ASI ports

The ASI-IP-GTW provides up to 8 DVB ASI ports. The unit can be delivered with 4 or 8 DVB ASI connectors. For the 4 ASI port version, 1, 2, 3 or all 4 ports can be enabled.
The operator can configure the unit as an IP transmitter, an IP receiver, or to IP bi-directional operation. In the IP transmitter mode, all enabled ASI ports are configured as DVB ASI inputs. In the IP receive mode, the ASI ports are configured as DVB ASI outputs. In IP bi-directional mode, half the DVB ASI ports are used as inputs, the other half as outputs (see
2.2.6)

1.1.1.18 DVB ASI input
Inputs connected to the DVB ASI ports should be on DVB compliant transport streams in asynchronous serial format.
Each DVB ASI connector has two LEDs associated with it; ASI Rx and Active. Both LEDs are lit when the ASI input is enabled and a DVB ASI stream is connected to the port. If the input is enabled, but no valid stream is connected to the port, only the ASI Rx LED is lit. If the ASI input is disabled none of the LEDs are lit.
1.1.1.19 DVB ASI output
When in IP receive mode, the ASI port will provide a DVB compliant transport stream. When no stream is received over the IP network, the output will be idle characters. If a stream is received, the output will be a combination of MPEG-2 transport stream data bytes and idle characters.
The ASI Rx is always unlit when the ASI port is configured as an ASI output. The LED, designated Active, is lit when the output is enabled and unlit when the output is disabled.

2.4.3 Ethernet data port

The Ethernet port provides an electrical Ethernet data port. The default interface is 100Base-T. As an option, the port can be operated as 1000Base-T. In this case the port can auto sense between 100 and 1000 Mbits/s. The operator is able to force the interface speed to fixed 100Mbit/s or fixed 1000Mbit/s. This is useful to minimize the synchronization time when reconnecting signal cables.

Type 10/100/1000Base-T Connector type RJ45
Two LEDs are associated with the Ethernet data port.
For flexibility, the ASI-IP-GTW provides an optional Small Form-Factor Pluggable (SFP) slot to carry a copper or optical SFP, allowing customers to use different SFPs for special distance, cost, existing infrastructure, and future expansion requirements. The ASI-IP-GTW is prepared for electrical (1000Base-T) or optical 1000BASE-SX and 1000BASE-LX SFP transceivers.

3 Op erating the Equipment

3.1 Introduction

The ASI-IP-GTW is configured and controlled locally and remotely through a flash-based WEB interface. The only application required on the computer to use this interface is a WEB browser (Internet Explorer, Mozilla or Opera) and FLASH player 7.0. In order to connect to the user interface of the ASI-IP-GTW only enter the IP address of the management data port. The default IP address of the management port is 10.0.0.10. Please refer to Section change the IP address of the management port using the RS232 connection.
Note: FLASH player 7.0 or newer is required to use the WEB interface
of the ASI-IP-GTW.
If you don’t have FLASH player 7.0 or newer installed on your computer, this will be detected and you will be informed to install this prior to configuring the ASI-IP-GTW.
3.2 for information about how to
Note: It is recommended to use Internet Explorer 6.0 or newer.
he ASI-IP-GTW can be configured to transmit MPEG2 transport stream data over an Ethernet link or receive data from an Ethernet interface. In IP transmit mode (IP TX), up to 8 DVB ASI inputs are provided. In IP receive mode (IP RX), up to 8 DVB ASI output streams are provided. An optional mode for bi-directional operation (IP-TXRX) is available, where half the DVB ASI ports are used as inputs, and the other half as outputs.

3.2 Changing the IP address of the unit

The ASI-IP-GTW is configured with IP address 10.0.0.10 for the management port. There are two ways to change the IP address of the management port:
1. Connect from a WEB browser and use WEB-interface to set IP address of management port (See section
2. Connect via RS232 via HyperTerminal (115200kb/s, 8, N, 1, no flow control). Type the following command:
net ipconfig --ip (ip address) --mask (subnet mask) -
-gw (gateway).
3.5.1).
Example:
net ipconfig --ip 10.40.80.100 --mask 255.255.255.0 -
-gw 10.40.80.1
Page 25
This will result in the IP address 10.40.80.100. The subnet mask is set to 255.255.255.0 and the default gateway to 10.40.80.1.
