The RV-8 responds to this command with a Communication Configuration Packet. 7. 3. 9. 1 Command Packet Description Application Header: Command DC_CMD_GET_COM_CONFIG Data Count 0 Application Data: N/A 0x2F 0x00 7. 3. 9. 2 Communication Configuration Response Packet Application Header: Command DC_RESP_COM_CONFIG Data Count 1 Application Data: Data[0] Configuration Register 0 0x8C 0x01 nn 7. 3. 9. 3 Data Description Data Word Bit Definition 0 0 Acknowledge Enable 0 1 Parameter Change Enable Acknowledge Enable: TRUE Indicates the RV-8 will transmit Acknowledge Notification's to the Host. FALSE Indicates the RV-8 will not transmit any positive Acknowledge Notification messages. Parameter Change Enable: TRUE Indicates the RV-8 will transmit any parameter change Notification as specified in the Parameter Change Notification Message. FALSE Indicates the RV-8 will not transmit parameter change Notifications. 19 Lexicon RV-8 Serial Communications Protocol 7. 3. 10 Set Communication Configuration The Set Communication Configuration Command allows the serial port user to set up the various serial port/ protocol configuration parameters. 7. 3. 10. 1 Command Packet Description Application Header: Command Data Count Application Data: Data[0] DC_CMD_SET_COM_CONFIG 1 Configuration Register 0 0x30 0x01 nn 7. 3. 10. 2 Data Description Data Word Bit Definition 0 0 Acknowledge Enable Acknowledge Enable: TRUE Indicates the RV-8 will transmit Acknowledge Notification's to the Host. FALSE Indicates the RV-8 will not transmit any positive Acknowledge Notification messages. The RV-8 will always transmit NAK error notification messages. 7. 3. 10. 3 RV-8 Response The data values transmitted will be copied over to the registers stored in nonvolatile RAM. 7. 3. 11 Set Mute The Set Mute Command message allows the RS-232 users to set/clear the RV-8 mute state directly. 7. 3. 11. 1 Command Packet Description Application Header: Command Data Count Application Data: Data[0] DC_CMD_SET_MUTE 1 Mute State 0x31 0x01 nn 7. 3. 11. 2 Data Description MUTE State: Value Definition 0 UNMUTE 1 2 USER MUTE FULL MUTE Description The user mute state is set to unmuted. The system volume decrements by the specified user amount as set in the OUTPUT LEVELS Menu. The system is fully muted. 7. 3. 11. 3 RV-8 Response 20 Lexicon RV-8 Serial Communications Protocol 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. 7. 3. 12. 1 Packet Description Application Header: Command Data Count Application Data: Data[0] Data[1]-Data[DataCount-1] DC_CMD_SET_DISPLAY_STR 0x33 Number of characters in the nn DisplayStr + 2 DisplayFlags DisplayStr nn ch ch ch . . . 0x00 7. 3. 12. 2 Data Description Display Command Flags: Word Bit Definition 0 0 FPD only: If set TRUE, the display string will only be sent to the FPD device for display. 0 7 Undefined.
