Passing the Status Bytes
The 9215-EO-EM replaces Channel Status Bytes according to Error! Reference source not found. or
passes Status Bytes through from input to output. The following conditions must be met for Status
Bytes to pass:
• AES inputs must be 48kHz synchronous
• SRC is set to OFF
• Data Word Length in the Channel Status Bytes must match what is embedded
