RS232 Pin-outs and Data Connections
Important Notes:
· It is important that you enable serial port flow control within the codec. Flow control
regulates the flow of data through the serial port. If disabled, data will flow unregulated and
some may be lost.
· Ensure you match the serial port baud rate to match the rate of the external device you are
connecting to. Ideally the settings on both codecs should match, or you could have data
overflow issues.
