XLR Platform Demo Examples

Sample Demo Setup with PC

Using SigmaStudio+ the A2B system can be directly controlled from a connected computer without involving a microcontroller or a DSP. This mode is helpful for quick testing of the capabilities of AD24xx without the need for a microcontroller in the system.

Note: Please refer to Appendices A and B for information about navigating in SigmaStudio+ for the A2B use case. A block diagram of a 3-node A2B system with PC as Host is shown below

Figure 6: Sample A2B demo configuration

Connections

To run the sample demo, the following setup connections are to be made.

Evaluation boards

A2B Evaluation boards shall be connected in the following order

  1. EVAL-AD2437A1NZ (Main) <–>EVAL-AD2437B1NZ (Sub 0) <–> EVAL-AD2437B1NZ (Sub 1) as shown in Figure 7.
  2. Connect XLR cable between the A2B connector on the Main board and the “A” connector on the Sub 0 board.
  3. Connect XLR cable between the “B” connector on the Sub 0 board and the “A” connector on the Sub 1 board.
  4. Connect 24V 3A power supply to the power connector (P14) on AD2437A1NZ board.
