recstr
Data recorder stride (store only every nth value)
0….65535
reclen
Memory length for each of the two data recorder
channels
0 …. 6144
0 = infinite loop over maximum length
until recorder is stopped manually
recrun
Start or stop the data recorder
0 = stop
1 = start
recout
Read out the data recorder line by line:
• ch: channel
• Index: Distance to index 0
• Length: number of values (max. to reclen or
rec_max)
Response:
recout, <ch>, <index>,<value>
ch:
0 = channel A
1 = channel B
Index:
0… 6143
Length:
1… 6144
recoutf
Read out the complete data recorder comma-
seperated:
Response:
recoutf, <ch>, <value 1>,<value 2>,….,<value
reclen>
ch:
0 = channel A
1 = channel B
