Dump Fast Memory to Slow Memory
Description: Moves spectral data from fast memory to slow memory. The current pixel mode parameters
are used to determine which pixel values are to be written to slow memory.
Command Syntax:
D
Response:
ACK or NAK. Generate a NAK value if an error occurs in the flash memory
writing operation. See error codes for explanation.
Default value:
None
Move Slow Memory Read Pointer
Description: Moves the slow memory read pointer
Command Syntax:
E{
DATA WORD
}
Value:
0 – Move read pointer to the beginning of slow memory
65535 – Move read pointer to the current write pointer location (end of valid
memory)
Response:
ACK or NAK. A NAK value can be generated if an error occurs while reading
the flash memory. See error codes for explanation.
Default value:
None
This command should be used with caution. Use this command to repeat the read out of slow
memory or skip over previously read out data.
A/D Rate
Description: Sets the A/D rate in kHz to the value specified.
Command Syntax:
F{
DATA WORD
}
Response:
ACK or NAK
Range:
1-500
Default value:
500
Compressed Mode
Description: Specifies whether the data transmitted from the SAD500 should be compressed to speed data
transfer rates. For more information on SAD500 Data Compression, see Technical Note 1.
Command Syntax:
G{
DATA WORD
}
Value:
0 = do not use data compression
1 = use data compression
Response:
ACK or NAK
Default value:
0
