where:
<STX> = 0x02
<ADDR> = 0x80 (for RS 232 and
RS 422 only)
<ADDR> = 0x80 + device number (0...31)
0xFF: brodcasting command
(recognized by all the devices, it
doesn't implicate any answer)
(for RS 485 only)
<WINDOWS>= ' 000 '...' 999' window number
the meaning of the window
depends to the device type
<COMMAND>= 0x30: window value reading
0x31: window writing
<DATA> = alphanumeric ASCII string
containing, in the case of writing
operation,the parameter to input
into the window addressed by
the field <WINDOW>This field
may have variable length
according to the data type
contained in the window where
you are working in. In the case of
Reading request of a window, the
data field doesn't exist.
<ETX>= 0x03
<CRC>= XOR among all the characters
following <STX>= (with exception of
<STX>), including the end character
<ETX> hexadecimally encoded by
two ASCII characters.
1) When a slave device is addressed by the master:
