2. Raw sampling mode: The data input is sampled at 93.75 kHz and embedded as a data
stream. No checking is performed.
6.4.9.2 Data latencies
The data channel has a total latency of approximately 900us when using raw sampling. Normal
data rates of up to 9600 may be used with raw data sampling to have a low latency. The latency is
2.6ms when using the normal data encoding due to the block structure of the AES User bits. The
configuration of the data channel is always stored in the module and used regardless of the GYDA
override switch.
6.4.9.3 Embedding
The AV-3G-XMUX has a RS422 data input for the embedding of control data. The mode and other
parameters are configured with GYDA. The factory default is UART mode, 115200 baud, no parity,
and one stop bit. The data channel is encoded in the User bits in an embedded audio stereo signal
assigned with GYDA. The factory default is Audio channels 1 & 2 in Group 1.
