DB<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
not used
bit 1
not used
bit 2
not used
bit 3
not used
<s2>
bit 0
voltage errors inside a cell
bit 1
not used
bit 2
not used
bit 3
not used
<s3>
bit 0
at least one cell with a temperature value outside the range
bit 1
new system
bit 2
scale card replaced
bit 3
only one cell replaced in multi-cell system
<s4>
bit 0
at least one cell is not connected
bit 1
at least one cell is not configured
bit 2
