[. . . ] 7. 3. 6. 4 Data Validation No data validation is done on the transmitted data. 7. 3. 7 Host Wakeup By transmitting the Wakeup Notification, the Host indicates it has just "powered on" or reset and is ready to receive RV-8 Notifications or Responses. The Host is assumed to be asleep upon power up of the RV-8. Host status is maintained during standby. 7. 3. 7. 1 Command Packet Description Application Header: Command HOST_WAKEUP Data Count 0 Application Data: N/A 0x11 0x00 7. 3. 7. 2 Data Description N/A 7. 3. 7. 3 RV-8 Response The RV-8 will respond to this command with an ACK. The unit also returns the input name, audio status, and mode. 18 Lexicon RV-8 Serial Communications Protocol 7. 3. 8 Host Sleep By transmitting the Sleep command, the Host indicates it has just "powered down" and will no longer respond to RV-8 Notifications. The Host is assumed to be asleep upon power up of the RV-8. Host status is maintained during standby. 7. 3. 8. 1 Packet Description Application Header: Command HOST_SLEEP Data Count 0 Application Data: N/A 0x12 0x00 7. 3. 8. 2 Data Description N/A 7. 3. 9 Get Communication Configuration This command is a request to the RV-8 for the current communications configuration for the serial port and protocol. 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. The RV-8 will always transmit NAK error 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. The RV-8 will respond with an ACK Packet. 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. [. . . ] RV-8 will respond with "Zone3 Status Packet". 7. 3. 23. 1 Command Packet Description Application Header: Command MC_CMD_GET_ZONE3_STATUS 0x3F Data Count 0 0x00 Application Data: N/A 7. 3. 23. 2 Zone 3 Status Response Packet Application Header: Command MC_RESP_ZON_STATUS Data Count 5 Application Data: Data[0] Zone3 Volume Data[1] Assigned Zone 3 Input Data[2] Zone3 Mute Active Data[3] Reserved Data[4] Zone3 Balance 0x95 0x05 nn nn nn 0 nn 7. 3. 23. 3 Data Description Zone 3 Volume: Data Type: Max: Min: Signed 8-bit integer (2's compliment) +12 (0x0C) (12 dB) -80 dB (0xB0) (-80 dB) Assigned Zone 3 Input: Indicates the Zone 3 input that is currently assigned for the Zone 3 outputs. Definition/Conversion: Appendix F RV-8 Input Ids Zone3 Mute Active: Data Type: TRUE: FALSE: Reserved 34 Boolean. Zone 3 Outputs are not active. Lexicon RV-8 Serial Communications Protocol Zone 3 Balance: Data Type: Max: Min: Signed 8-bit integer (2's compliment) 16 (0x10) (Full Right) -16 (0xF0) (Full Left) 7. 3. 24 Set System Volume This command is a request to the RV-8 to set the system volume with the value in this packet. 7. 3. 24. 1 Command Packet Description Application Header: Command MC_CMD_SET_SYS_VOLUME Data Count 1 Application Data: Data[0] Value 0x40 0x01 nn 7. 3. 24. 2 Data Description Value: Data Type: Max: Min: Signed 8-bit integer (2's compliment) +12 (0x0C) (12 dB) -80 (0xB0) (-80 dB) 7. 3. 24. 3 RV-8 Response The RV-8 will assign the value from the packet to the system volume. 7. 3. 24. 4 Data Validation If a value is passed that exceeds the maximum value of that parameter the RV-8 will ignore the command and transmit a DC_NAK command with an error code DC_INVALID_DATA. 7. 3. 25 Set Main Balance Commands RV-8 to set the system balance to the value in this packet. 7. 3. 25. 1 Command Packet Description Application Header: Command DC_CMD_SET_SYS_BALANCE Data Count 1 Application Data: Data[0] Value 0x41 0x01 nn 7. 3. 25. 2 Data Description Value: Data Type: Max: Min: 7. 3. 25. 3 RV-8 Response Signed 8-bit integer (2's compliment) +16 (0x10) (Full Right) -16 (0xF0) (Full Left) 35 Lexicon RV-8 Serial Communications Protocol The RV-8 will assign the value from the packet to the system balance.
