VES: Value of the VES measured on the QC sample, ASCII string without terminator:
from “ 0” (3 spaces + ‘0’) transmitted in the case of an error, to “ 140” (1 space + “140”). If
the result is higher than 140 the string will be “>140”
EXAMPLES, see following table:
VES value
String sent
Bytes of the String
1
“ 1”
0x20, 0x20, 0x20, 0x31
100
“ 100”
0x20, 0x31, 0x30, 0x30
>140
“>140”
0x3E, 0x31, 0x34, 0x30
H-FLAGS / L-FLAGS: Bitmap with 8-bit of the sample errors, represented in HEX-ASCII.
The following table illustrates the errors:
Bit
Error
Description
0
Sample High
Blood column too high
1
Sample Low
Blood column too low
2
Sample Absent
Tube Empty
3
Abnormal
Error in acquisition of height
4
QC PASS
The VES of the QC measured is within the
acceptability range
5
QC FAIL
The VES of the QC measured is outside the
acceptability range
6-7
-
Reserved
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 “QC Fail” error the Bit 5 will be set to one and all the others to zero,
therefore the byte of the Flags will have a 0x20 hexadecimal value and its HEX-
ASCII representation will be 0x32 / 0x30
RACK ID: string of 4 characters without terminator, identifies the classifier rack in which
the sample has been repositioned.
POSITION: string of 2 characters without terminator, identifies the coordinates of the
position in which the sample has been repositioned in the Classifier rack.
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.
