then refer to Annex G, Audio Modes, for information about using this

mode.

Mux Fault-finding

If there is no output from the ASI connectors, check the following:
1. The bit-rate - if it is too low then the video etc. is automatically

switched off.

2. The packet length - should be 188 or 204 bytes depending upon

configuration.

Rate Buffer Setting

The E5710/E5720 Encoders, when running in 4:2:2

1

mode, have two

software selectable rate buffer modes; small and medium.
When transmitting 4:2:2

1

mode into systems using the earlier System

3000 PRO IRD M2/PSR/3/422BAS then the rate buffer mode of the

Encoder must be set to 'small'.
However, when operating into an Alteia the rate buffer mode of the

Encoder must be set to ‘medium’ (default size).
When operating in mixed environments, both the Alteia and the Encoder

must be changed to small buffer mode.

NOTE…
Contact Customer Services for advice about changing the settings (see Preliminary Pages).
