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. 49 (MC12_Set_Front_Back_Balance). 7. 3. 20. 1 Packet Description Application Header: Command DC_CMD_SET_FRONT_BACK_BALANCE Data Count 1 Application Data: Data[0] Value 0x23 0x01 nn 7. 3. 20. 2 Data Description Value: Data Type: Max: Conversion: Unsigned 8 bit integer. 32 0 = Front 16 = Center 32 = Back 7. 3. 20. 3 MC-12 Response © 2005 Harman Specialty Group All rights reserved. 27 of 106 Lexicon MC-12 Serial Communications Protocol The MC-12 will assign the value from the packet to the front/back balance. Printed on: 07/13/05 7. 3. 20. 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. 21 Set Active Effect by Id (MC-12, MC-1) This command requests the MC-12 to set the active effect 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. 50 (MC12_Set_Active_Effect_By_Id). 7. 3. 21. 1 Command Packet Description Application Header: Command DC_CMD_SET_EFFECT Data Count 1 Application Data: Data[0] EffectId 0x24 0x01 nn 7. 3. 21. 2 Data Description EffectId: Data Type: Unsigned 8 bit integer Definition/Conversion: Appendix I MC-1 to MC-12 Effect ID Map. 7. 3. 21. 3 MC-12 Response The MC-12 will load the desired effect. 7. 3. 21. 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. 22 Set Record Input (MC-12, MC-1) Sets the Record 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.
