The RV-8 will set the mute state according to the value transmitted. The RV-8 may still be full
muted if other conditions require the audio path to be muted. This is only a direct access to the
user mute state.
7.3.11.4 Data Validation
The data value transmitted to the RV-8 will be verified as a valid value. If it is valid the RV-8 will
set/clear the mute and respond with an ACK Packet. If the data value is invalid the RV-8 will
respond with a DC_INVALID_DATA error NAK.
7.3.12 Send Display String Command
This command allows the Host to send a 40-character string to the RV-8 for display on the OSD
and Front Panel Display. This can be configured such that the message will display only on the
FPD, if desired.
