Page 9: The Streaming Ports
Please DO NOT attempt to connect RAVENNA interfaces using an unqualifying IP network, as correct streaming operation cannot be guaranteed. You can find more details about the data network requirements in the Lawo IP Networking Guide. Network Cables & Connectors... - Page 10 To configure SMPTE 2022-7 within a RAVENNA streaming network, will need to create the two separate paths for each data stream. This means doubling the network's infrastructure and then connecting each sending and receiving device to both paths. Within Lawo systems, the two paths are usually known as the primary (red) and secondary (blue) networks.
- Page 11 5. The Streaming Ports Port Labeling On the rear connector panel, the two streaming ports are labeled as ETHERNET A and ETHERNET B. However, on the front panel display and within the RAVENNA Web UI, they appear as ra0 and ra1.

- Page 45 11. The RAVENNA Web UI 11.13 Creating SMPTE 2022-7 Compatible Streams To support SMPTE 2022-7 (streaming redundancy), a stream must be transmitted and received via two separate network paths. For an A__line device, the TX or RX interfaces are ETHERNET A (ra0) + ETHERNET B (ra1). TX Stream Properties First, open a RAVENNA Web UI connection to the sending device and make sure that the 'TX Stream Properties' are configured to use both RAVENNA interfaces.
- Page 46 11. The RAVENNA Web UI RX Stream Properties: Pre-configured Now open a RAVENNA Web UI connection to the receiving device and, if possible, select the TX stream from the Connect menu - the 'RX Stream Properties' window opens. The Stream Source will be completed automatically from the stream's SDP information, and the Receiver Settings will be pre-configured according to the default settings.
- Page 47 11. The RAVENNA Web UI RX Stream Properties: Using a Custom URL If the TX stream does not appear in the Connect menu, then you will need to select Using a Custom URL define the Stream Source fields manually. As before, the simplest way to do this is to copy and paste the SDP or RTSP URLs from the sending device.
- Page 48 11. The RAVENNA Web UI 11.14 The Routing Matrix The Routing Matrix maps the device's local audio signals to and from the RAVENNA media. Together with the Recording track assignments (for TX streams) and Play track assignments (for RX streams), this determines the audio path to and from the network.
- Page 49 11. The RAVENNA Web UI 11.15 Batch Create The Batch Create function can be used to quickly create a series of similarly-configured TX or RX streams. For example: Use the Create button to open the 'TX Stream Properties' window and enter the parameters required for the first stream.
- Page 50 11. The RAVENNA Web UI 11.16 Selecting Streams You will need to select a stream to delete it or make it active or inactive via the Toggle button. In each case, the following methods can be applied to either TX or RX streams: Click on an individual entry to select (or deselect) the stream - the complete line is highlighted whenever a stream is selected.

13. Software Tools & Diagnostics Software Tools & Diagnostics 13.1 Configuration Backup & Restore This tool will backup and restore the complete RAVENNA configuration. It is ideal if you need to exchange a device. Note that this function is identical to the Backup and restore config function available from the Expert Settings menu of the RAVENNA Web UI. - Page 58 13. Software Tools & Diagnostics Ø To restore a configuration file: Open the Configuration backup & restore home page as before, but this time on the replacement unit. When you restore a configuration, you will override all of the device's RAVENNA settings. Therefore, make sure that you are connected to the correct unit before performing a restore! Click on the Browse button, select the backup file and then click on Open.
- Page 59 13. Software Tools & Diagnostics 13.2 Service Support This tool will download a current snapshot of the device settings into a "snaphot.sh" file. The file can be useful for Lawo support when diagnosing a problem. Ø To download the snapshot file: Open the Landing page in service mode, select Service Support and then click on the graphical preview.
- Page 60 All parameters within the A__mic8 / A__digital8 are accessible via Ember+. This allows an external control system, such as a Lawo console or VSM, to remotely control or respond to parameter changes within the device. From Image Version 10.0.0, this includes the internal Routing Matrix which maps the device's local IO signals to and from the RAVENNA streams.
- Page 61 13. Software Tools & Diagnostics 13.4 Running a PING Test The PING command is a built-in Windows and Mac function, that allows you to test whether you have a valid network connection to and from any networked device. Make sure that your computer is connected to the correct network port, and that you have configured the TCP/IP settings of your computer's network interface card.
- Page 62 13. Software Tools & Diagnostics Ø Ping Test Fail If the ping test fails, then the request will time out, and you will not receive any successful packets: There is something wrong with your network configuration, so check the network connections, and TCP/IP settings again.
