8 Commands and responses
8.5
Datalogger commands
The SQM-LU-DL-V contains datalogging capabilities.
All of the datalogging commands begin with “L”.
8.5.1 FLASH ID report
The FLASH memory chip stores all the data logging records. It does not contain any calibration information.
The ID report is useful for determining the exact model of FLASH device inside the SQM-LU-DL-V for record capacity
calculations.
To get a report on FLASH chip Manufacturer ID, and Device ID, use “
L0x
”. The response is shown in table 8.19:
Table 8.19: Response of requesting the FLASH chip ID
Column
Example value
Description
0-2
L0,
Confirmation of command.
3-5
000
Manufacturer ID.
6-8
000
Device ID.
9-10
Carriage return (0x0d), Line feed (0x0a).
An example response is:
L0,000,000
0123456789 1
8.5.2 Logging pointer report
To get a report on current logging pointer position, use the “
L1x
” command.
This pointer is the record address of where the next record will be stored.
Note: Before feature 27, the pointer position was only 6 characters long, from feature 27 onwards, the pointer position
is 10 characters long. The response is shown in table 8.20:
Table 8.20: Response of requesting the data logging pointer
Column
Example value
Description
0-2
L1,
Confirmation of command
3-12
0000000000
Pointer position
0 means that no records have been stored.
1 means that one record has been stored.
When the FLASH memory is full, this number will always point to
the last record and will be equal to the storage capacity (see LZx).
I.e. 1048575 for the larger memory
13-14
Carriage return (0x0d), Line feed (0x0a).
An example response is:
L1,0000000000
