EXAMPLES:
-
In the case of a “Sample High” error the Bit 0 (least
significant) will be set to one and all the others to zero,
therefore the byte of the Flags will have a 0x01
hexadecimal value and its HEX-ASCII representation will
be 0x30 / 0x31.
-
In the case of a “Sample Absent” error the Bit 2 will be set
to one and all the others to zero, therefore the byte of the
Flags will have a 0x04 hexadecimal value and its HEX-
ASCII representation will be 0x30 / 0x34.
Managing Errors in RESULTS:
If a Test Tube Record is sent with a VES value equal to 0 and an Error Flag
enabled (Bit 3 set to 1), the result (VES=0) must be interpreted by the Host as a
‘Reading Error of the sample’.
RACK ID
:
Not Used, always “0000”(string of 4 characters without
terminator)
POSITION
:
string of 2 characters without terminator, identifies the position
occupied by the sample into the instrument (“01”…..”04”).
H-CHK / L-CHK:
CheckSum of the message, represented in HEX-ASCII. The Checksum is
calculated by carrying out the OR-exclusive of all the bytes sent from STX to ETX
inclusive. The resulting hexadecimal value is then converted into HEX-ASCII and
the two characters that represent it are sent.
ATTENTION:
for debugging purposes it is possible to disable the checksum
control, replacing the H-COM bytes with the value of 0x44 instead of 0x35. In this
case the two bytes of the checksum are still sent but their value will be
insignificant. The Host computer must also manage any possible cases in which
the checksum is disabled.
