2.7.7
System cell number request
DN<CR>
The terminal responds with the string:
n<CR><LF>
n = number of cells that comprise the system.
2.7.8
Cell status request
DSc<CR>
The terminal responds with the string:
<s1><s2><s3><s4><CR><LF>
Characters such as s1, s2, s3, s4 are ASCII characters that must be interpreted as expressed in
hexadecimals. Each character represents 4 bits with different meanings, for example incoming ASCII
character "A" must be interpreted as hexadecimal digit "A":
1
0
1
0
bit3
bit2
bit1
bit0
When a bit has a value of "1" this means that the corresponding signal is in true condition; the
meaning of the signals is as follows:
<s1>
bit 0
temperature error
bit 1
not used
bit 2
not used
bit 3
not used
<s2>
bit 0
cell not connected
bit 1
cell not configured
bit 2
serial number error
bit 3
voltage error
<s3>
bit 0
reserved
bit 1
reserved
bit 2
not used
bit 3
cell in warm up condition
<s4>
bit 0
offset
bit 1
temperature reading phase
bit 2
voltage reading phase
bit 3
calibration reading phase
