[. . . ] This command has been maintained for backward compatibility with MC-1. In order to maintain backward compatibility, the MC-8 Parameters have been mapped to the MC-1 parameters as described in each Data Description. MC-8 users should be using the command described in 6. 3. 39 MC8_Set_Zone2_Left_Right_Balance). 6. 3. 14. 1 Packet Description Application Header: Command DC_CMD_SET_ZONE2_BALANCE Data Count 1 Application Data: Data[0] Value 0x28 0x01 nn 6. 3. 14. 2 Data Description Value: Data Type: Max: Conversion: Unsigned 8 bit integer 32 0 = Left 32 = Right 6. 3. 14. 3 MC-8 Response The MC-8 will assign the value from the packet to the Zone 2 balance. 6. 3. 14. 4 Data Validation If a value is passed that exceeds the maximum value of that parameter the MC-8 will ignore the command and transmit a NAK command with an error code DC_INVALID_DATA. 6. 3. 15 Set Custom Name Sets the Custom Name that can be displayed when the unit powers up. 6. 3. 15. 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 6. 3. 15. 2 Data Description CustomNameEnable: DataType: TRUE: Enables/Disables the Custom Name Display. MC-8 Serial Communications Protocol FALSE: CustomName: Data Type: Max Length: CustomName Disabled Printed on: 04/01/03 Null (0x00) terminated ASCII character string. CUSTOM_NAME_LENGTH defined in Appendix G Protocol Constants. 6. 3. 15. 3 MC-8 Response If the custom name enable is TRUE then the custom name banner is display on "power on". The MC-8 will ACK when completed with this command. 6. 3. 15. 4 Data Validation: No data validation is done on the transmitted data. 6. 3. 16 Set Input Name by Id 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-8 Parameters have been mapped to the MC-1 parameters as described in each Data Description. MC-8 users should be using the command described in 6. 3. 41 (MC8_Set_Input_Name_By_Id). 6. 3. 16. 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 6. 3. 16. 2 Data Description InputId: Data Type: Description/Conversion: InputName: Data Type: Max Length: Unsigned 8 bit Integer Appendix F MC-8 Input Id's Null (0x00) terminated ASCII character string. INPUT_NAME_LENGTH defined in Appendix G Protocol Constants. 6. 3. 16. 3 MC-8 Response MC-8 will copy the InputName to the given input. 6. 3. 16. 4 Data Validation: The InputId must be a valid Input Id. If it is not the MC-8 will respond with a NAK packet and error code DC_INVALID_INPUT. If the InputName string exceeds the INPUT_NAME_LENGTH, the MC-8 will truncate the string to the INPUT_NAME_LENGTH. © 2003 Lexicon, Inc. MC-8 Serial Communications Protocol Printed on: 04/01/03 6. 3. 17 Host Wakeup By transmitting the Wakeup Notification, the Host indicates it has just "powered on" or reset and is ready to receive MC-8 Notifications or Responses. Host status is maintained during standby. 6. 3. 17. 1 Command Packet Description Application Header: Command HOST_WAKEUP Data Count 0 Application Data: N/A 0x11 0x00 6. 3. 17. 2 Data Description N/A 6. 3. 17. 3 MC-8 Response The MC-8 will respond to this command with an ACK. 6. 3. 18 Host Sleep By transmitting the Sleep command, the Host indicates it has just "powered down" and will no longer respond to MC-8 Notifications. Host status is maintained during standby. 6. 3. 18. 1 Packet Description Application Header: Command HOST_SLEEP Data Count 0 Application Data: N/A 0x12 0x00 6. 3. 18. 2 Data Description N/A 6. 3. 19 Get Communication Configuration This command is a request to the MC-8 for the current communications configuration for the serial port and protocol. The MC-8 responds to this command with a Communication Configuration Packet. 6. 3. 19. 1 Command Packet Description Application Header: Command DC_CMD_GET_COM_CONFIG Data Count 0 Application Data: N/A 0x2F 0x00 © 2003 Lexicon, Inc. MC-8 Serial Communications Protocol Printed on: 04/01/03 6. 3. 19. 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 6. 3. 19. 3 Data Description Data Word 0 0 Bit 0 1 Definition Acknowledge Enable Parameter Change Enable Acknowledge Enable: TRUE Indicates the MC-8 will transmit Acknowledge Notification's to the Host. FALSE Indicates the MC-8 will not transmit any positive Acknowledge Notification messages. Parameter Change Enable: TRUE Indicates the MC-8 will transmit any parameter change Notification as specified in the Parameter Change Notification Message. FALSE Indicates the MC-8 will not transmit parameter change Notifications. 6. 3. 20 Set Communication Configuration The Set Communication Configuration Command allows the serial port user to set up the various serial port/ protocol configuration parameters. 6. 3. 20. 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 6. 3. 20. 2 Data Description Data Word 0 0 Bit 0 1 Definition Acknowledge Enable Parameter Change Enable Acknowledge Enable: TRUE Indicates the MC-8 will transmit Acknowledge Notification's to the Host. [. . . ] These Parameter Id Values will change with S/W and Protocol version changes. The MC8 can always be queried for the correct Parameter Id numbers and Parameter Definition Packets.
