[. . . ] MC-12 Serial Communications Protocol Printed on: 05/31/02 7. 3. 24. 1 Command Packet Description Application Header: Command DC_CMD_SET_ZONE2_VOLUME Data Count 1 Application Data: Data[0] Value 0x27 0x01 nn 7. 3. 24. 2 Data Description Value: Data Type: Max: Conversion: Unsigned 8 bit integer. 92 0 = -80 dB 92 = +12 dB 7. 3. 24. 3 MC-12 Response The MC-12 will assign the value from the packet to the Zone 2 volume. 7. 3. 24. 4 Data Validation If a value is passed that exceeds the maximum value of that parameter the MC-12 will ignore the command and transmit a NAK command with an error code DC_INVALID_DATA. 7. 3. 25 Set Zone2 Left/Right Balance (MC-12, MC-1) Commands MC-12 to set the Zone 2 balance to the value in this packet. This command has been maintained for backward compatibility with MC-1. In order to maintain backward compatibility, the MC-12 Parameters have been mapped to the MC-1 parameters as described in each Data Description. MC-12 users should be using the command described in 7. 3. 53 (MC12_Set_Zone2_Left_Right_Balance). 7. 3. 25. 1 Packet Description Application Header: Command DC_CMD_SET_ZONE2_BALANCE Data Count 1 Application Data: Data[0] Value 0x28 0x01 nn 7. 3. 25. 2 Data Description Value: Data Type: Max: Conversion: Unsigned 8 bit integer 32 0 = Left 32 = Right 7. 3. 25. 3 MC-12 Response The MC-12 will assign the value from the packet to the Zone 2 balance. © 2002 Lexicon, Inc. MC-12 Serial Communications Protocol Printed on: 05/31/02 7. 3. 25. 4 Data Validation If a value is passed that exceeds the maximum value of that parameter the MC-12 will ignore the command and transmit a NAK command with an error code DC_INVALID_DATA. 7. 3. 26 Set Custom Name (MC-12, MC-1) Sets the Custom Name that can be displayed when the unit powers up. 7. 3. 26. 1 Packet Description Application Header: Command Data Count Application Data: Data[0] Data[1]-Data[DataCount-1] DC_CMD_SET_CUST_NAME 0x2C Number of characters in CustomName + 2 nn CustomNameEnable CustomName nn ch ch ch . . . 0x00 7. 3. 26. 2 Data Description CustomNameEnable: DataType: TRUE: FALSE: CustomName: Data Type: Max Length: Enables/Disables the Custom Name Display. Boolean CustomName Enabled CustomName Disabled Null (0x00) terminated ASCII character string. CUSTOM_NAME_LENGTH defined in Appendix G Protocol Constants. 7. 3. 26. 3 MC-12 Response If the custom name enable is TRUE then the custom name banner is display on "power on". The MC-12 will ACK when completed with this command. 7. 3. 26. 4 Data Validation: No data validation is done on the transmitted data. 7. 3. 27 Set Input Name by Id (MC-12, MC-1) Sets an Input Name to the transmitted value for a given input. This command has been maintained for backward compatibility with MC-1. In order to maintain backward compatibility, the MC-12 Parameters have been mapped to the MC-1 parameters as described in each Data Description. MC-12 users should be using the command described in 7. 3. 55 (MC12_Set_Input_Name_By_Id). © 2002 Lexicon, Inc. MC-12 Serial Communications Protocol Printed on: 05/31/02 7. 3. 27. 1 Command Packet Description Application Header: Command Data Count Application Data: Data[0] Data[1]-Data[DataCount-1] DC_CMD_SET_INPUT_NAME 0x2E Number of characters in InputName + 2 nn InputId InputName 0 to 7 ch ch ch . . . 0x00 7. 3. 27. 2 Data Description InputId: Data Type: Description/Conversion: InputName: Data Type: Max Length: Unsigned 8 bit Integer Appendix F MC-12 Input Id's Null (0x00) terminated ASCII character string. INPUT_NAME_LENGTH defined in Appendix G Protocol Constants. 7. 3. 27. 3 MC-12 Response MC-12 will copy the InputName to the given input. 7. 3. 27. 4 Data Validation: The InputId must be a valid Input Id. If it is not the MC-12 will respond with a NAK packet and error code DC_INVALID_INPUT. If the InputName string exceeds the INPUT_NAME_LENGTH, the MC-12 will truncate the string to the INPUT_NAME_LENGTH. 7. 3. 28 Set FPD Control Registers (MC-1) This command is not supported by the MC-12. 7. 3. 29 Host Wakeup (MC-12, MC-1) By transmitting the Wakeup Notification, the Host indicates it has just "powered on" or reset and is ready to receive MC-12 Notifications or Responses. Host status is maintained during standby. 7. 3. 29. 1 Command Packet Description Application Header: Command HOST_WAKEUP Data Count 0 Application Data: N/A 0x11 0x00 7. 3. 29. 2 Data Description N/A 7. 3. 29. 3 MC-12 Response The MC-12 will respond to this command with an ACK. © 2002 Lexicon, Inc. MC-12 Serial Communications Protocol Printed on: 05/31/02 7. 3. 30 Host Sleep (MC-12, MC-1) By transmitting the Sleep command, the Host indicates it has just "powered down" and will no longer respond to MC-12 Notifications. Host status is maintained during standby. 7. 3. 30. 1 Packet Description Application Header: Command HOST_SLEEP Data Count 0 Application Data: N/A 0x12 0x00 7. 3. 30. 2 Data Description N/A 7. 3. 31 Get Communication Configuration (MC-12, MC-1) This command is a request to the MC-12 for the current communications configuration for the serial port and protocol. The MC-12 responds to this command with a Communication Configuration Packet. 7. 3. 31. 1 Command Packet Description Application Header: Command DC_CMD_GET_COM_CONFIG Data Count 0 Application Data: N/A 0x2F 0x00 7. 3. 31. 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. 31. 3 Data Description Data Word 0 0 Bit 0 1 Definition Acknowledge Enable Parameter Change Enable Acknowledge Enable: TRUE Indicates the MC-12 will transmit Acknowledge Notification's to the Host.
