[. . . ] For multi-byte data, the values are packed LSB first(CurrentValue [0]) to MSB(CurrentValue [0+(num bytes-1)]). For example: Setting a given signed 16 bit parameter to a value of 300 the data array would be packed as follows: Data[0] = 0xd4 Data[1] = 0xfe Data[2 - 13] = don't care. If a parameter's current value is a signed 16 bit parameter with a value of -3 the data array would be packed as follows: Data[0] = 0xfd Data[1] = 0xff Data[2 - 13] = don't care. All signed values are in the 2's compliment format. Max Value: This is a 16 bit value representing the maximum value for a parameter. Parameter values exceeding the maximum will be limited to the maximum. This may be a signed or unsigned value depending on the Parameter Type. RV-8 Serial Communications Protocol Printed on: 07/26/05 This is a 16 bit value representing the minimum value for a parameter. Parameter values exceeding the minimum will be limited to the minimum. This may be a signed or unsigned value depending on the Parameter Type. Parameter Path: This is a zero terminated ASCII character string describing the parameter's name and path in the units parameter tree structure. Read Only: Data Type: TRUE: FALSE: Boolean Parameter is read only Parameter is writeable 7. 3. 14 Set Parameter Value by Id RV-8 Set Parameter by Id command sets the parameter value equal to the value sent in the command packet and then runs the appropriate functional changes associated with changing the given parameter. 7. 3. 14. 1 Command Packet Description Application Header: Command MC_CMD_SET_SYS_PARAM_VALUE_BY_ID Data Count 24 Application Data: Data[0] ParamId(LSB) Data[1] ParamId(MSB) Data[2] ParamType Data[3-23] Value[0 -20] 0x36 0x18 nn nn nn nn nn nn. . . 7. 3. 14. 2 Data Description ParamId: Data Type: Max Value: Unsigned 16 bit Integer Max Parameter Count as reported by the RV-8 Unit Configuration Response Packet in 7. 3. 16. 2 ParamType: Param Type Name PARAM_TYPE_UINT8 PARAM_TYPE_UINT16 PARAM_TYPE_CSTR8 PARAM_TYPE_CSTR13 PARAM_TYPE_UINT32 PARAM_TYPE_BOOLEAN PARAM_TYPE_INT8 PARAM_TYPE_BRANCH Param Type ID 0 1 2 3 4 5 6 7 Type Description Unsigned 8 bit integer(0 to 255) Unsigned 8 bit integer(0 to 65535) Zero terminated string of 8 ascii characters Zero terminated string of 13 ascii characters Unsigned 32 bit integer (0 to 4, 294, 967, 295 ) Boolean (0 to 1) Signed 8 bit integer (-127 to 128) Parameter Branch Data Size (Bytes) 1 2 9 14 4 1 1 N/A © 2005 Lexicon, Inc.

RV-8 Serial Communications Protocol PARAM_TYPE_INT16 PARAM_TYPE_CSTR20 PARAM_TYPE_ARRAY 8 9 10 Printed on: 07/26/05 Signed 16 bit integer (-32, 767 to 32, 768) Zero terminated string of 20 ascii characters Unsigned 16 bit number representing the number of elements in the array, another 16 bit number representing the number of bytes in an ArrayItem Unsigned 16 ParamId, Unsigned 8 bit ParamType, Unsigned 16 ArrayItem Index, Unsigned 8 Databytes 0 to 128 2 21 4 PARAM_TYPE_ARRAYITEM 11 133 Value: The data value transmitted is dependent on the ParamType, as described above. The Data Value is always packed starting at the Value[0] byte in the packet. For multi-byte data, the values are packed LSB first(Value[0]) to MSB(Value[0+(num bytes-1)]). For example: Setting a given signed 16 bit parameter to a value of -300 the data array would be packed as follows: Value[0] = 0xd4 Value[1] = 0xfe Value[2 - 13] = don't care. All signed values are in the 2's compliment format. 7. 3. 14. 3 Data Validation: The ParamId must be a valid Parameter. The ParamType must be valid for the given ParamId. If either of these condition is not true the RV-8 will respond with a NAK packet and error code DC _ INVALID_PARAM_ID. The data value size cannot exceed the size of a given data type. A value that does exceed the size of a give data type will be truncated to the appropriate size. The ParamType transmitted must match the ParamType for the Parameter being transmitted, as per the Parameter Definition as transmitted by the MC_SYS_PARAM_DEF_PKT . If the types do not match The RV-8 will transmit a NAK packet with a DC_INVALID_INPUT error code. [. . . ] All rights reserved. 60 of 72 Lexicon, Inc.
