The iAM rear panel AoIP jack supports 1Gb/s and 100Mb/s Ethernet devices in Ravenna Audio over IP network configurations. iVAM2-2 channel source selections are made by choosing Input Type ‘AoIP’ in the Configuration-Configure Presets page regardless of which AoIP option is installed.
  • Page 108 The Merging Ravenna card runs specific firmware from Merging and augmented by Wohler for use within the iVAM2-2. The card will not function correctly if the user downloads and installs firmware from any source besides Wohler. The Wohler augmentation includes the ability to support 64 channels.

  • Page 118 Introduction This appendix discusses ways to use the Application Program Interface (API) to allow third party equipment to remotely access options and settings of the iVAM2-2. It includes specific code examples for commonly used requests. The API uses JavaScript Object Notation (JSON) as its communication language.
