    4. Controls, Connectors & Indicators Controls, Connectors & Indicators Status LEDs (PSU1, PSU2 & FAN) The three LEDs indicate the status of the two internal power supplies and the cooling fan. For the PSUs: green = normal operation; off = PSU error or no power connected. For the fan: off = normal operation; red = fan error detected.
  • Page 8 4. Controls, Connectors & Indicators Power (PSU 1 & 2) The unit is fitted with two independent power supplies running in parallel. Only one supply is required for operation. For redundancy, connect both supplies, each to a separate AC mains circuit. The PSU LEDs on the front panel show the status of each supply.

  • Page 9: The Conversion Modes

    Note that the conversion mode for each BRIDGE module can be selected independently. RAVENNA Link to/from MADI (DALLIS) This mode converts Lawo's RAVENNA Link to MADI; both audio and control are converted. The mode is designed to connect an existing DALLIS (with MADI master board) to a mc /Nova RAVENNA IO Module via RAVENNA Link.
  • Page 10 This mode converts RAVENNA Net to and from MADI; only audio is converted. Use this mode to integrate any MADI device (Lawo or third-party) into an AES67/RAVENNA streaming network. If both ETHERNET A and ETHERNET B ports are connected, then the BRIDGE can support redundant streaming SMPTE 2022-7 (SPS).

  • Page 11: The Ravenna 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. A__madi4 User Guide Version: 10.0.0/4...
  • Page 12 To use the optical fibre ports, please fit one of the Lawo-certified Modules. Note that the SFPs must be Lawo-certified. Options include mulit-mode and single-mode fibre, supporting a choice of maximum cable lengths. If Both Copper and Fibre are Connected If both copper and fibre are installed at start-up, fibre is the preferred medium.
  • Page 13 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 14 6. The RAVENNA Ports Port Labeling On the front connector panel, the two RAVENNA ports are labeled as ETHERNET A and ETHERNET B. However, within the RAVENNA Web UI, they appear as ra0 and ra1. This is important to know when editing settings for the RAVENNA Net streaming ports using the Web UI: Front Connector Panel Network Interfaces (in the Web UI)

    7. Synchronization Synchronization Sync Reference Options The sync reference options for each BRIDGE module depend on the conversion mode. Converting to/from RAVENNA Link In both RAVENNA Link modes, the master clock source for the BRIDGE is its RAVENNA Link port. Note that neither the MADI port or Wordclock input can be used as an external clock source when operating in this mode.

  • Page 19 The following SFP modules are available for the relevant MADI and RAVENNA ports. Note that all SFPs must be Lawo-certified (as listed below). If fitting SFPs to both MADI and RAVENNA ports, take care not to mix up the module types! MADI SFP Modules Options include multi-mode and single-mode fibre, and standard coaxial cable.
  • Page 20 8. Installing the Unit Getting Operational Once the unit has booted, the next steps are: Connect a computer directly to BRIDGE 1 via its ETHERNET A port and open the Device Configuration page. From here you should check the software version. Then select the conversion mode. When converting to/from RAVENNA Link, the setup is complete and you can skip straight to step 3.

    For example, if the unit has the default service network IP address of 192.168.110.253, then set your computer's IP address to 192.168.110.255. Ø Subnet Mask The Subnet Mask must match that of the port you are connecting to. In all Lawo systems, the default Subnet Mask = 255.255.255.0. Ø Default Gateway A Default Gateway setting is required if data packets are to be redirected.

  • Page 45 12. The RAVENNA Web UI 12.12.4 Copying & Pasting SDP / RTSP URLs To copy and paste the SDP information from a sending device: Open a Web UI connection to the sending device, and click on the TX stream: At the bottom of the window, click on the SDP button to copy the stream's SDP information to the clipboard.
  • Page 46 12. The RAVENNA Web UI A similar method can be used to copy and paste the RTSP URLs: On the sending device, use the RTSP URL buttons in the 'TX Stream Properties' window to copy the address for the sending interface. Then on the receiving device, paste the clipboard contents into the Stream Source field: If the TX stream is redundant, copy and paste the URL for the each of the sending interfaces separately - enter the ra0 URL into the upper field and the ra1 URL into the lower field.

  • Page 49 12. The RAVENNA Web UI 12.13 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 50 12. 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.
