Important Notice:
Any modification to the Variable Serial Protocol is restricted to qualified personnel only.
The Biotecnica Instruments S.p.A. guaranties the correct performance of the internal
serial protocol. The responsibility for any malfunction arising out of any modifications to
the scripts of the Variable Serial Protocol rests with the customer.
WARNING
This information regards the setting up of the barcode for sample tubes identification. The
reading of the sample barcode label has the same progression as patient code.
For example: Once a patient code of 15 characters has been entered, then a code of 8
characters followed by 7 empty spaces to reach the 15 characters is sent.
The code read on the barcode label must have the same sequence 8 + 7 for correct
detection.
SERIAL COMMUNICATION OF THE BT3000 PLUS
TO A HOST COMPUTER
4-1. GENERAL
The analyzer BT 3000 PLUS allows bidirectional communication through RS 232C serial
connection with any host computer.
The particular feature of the dialog is that it is always the host computer, which initiates
the communication for either transmitting patient list or for receiving the results.
To initiate any communication the host computer will have to send to analyzer the
character STX (0x02) and expect the character ACK (0x06) as a response. At this point
the host computer will send data to the analyzer and terminate the communication by
sending the character EOT (0x04).
It is important to remember that any communication is followed by a response from the
analyzer.
It must be noted that if the parameter to be transmitted is shorter in length than the length
requirement of the communication protocol than a space must be added before or after.
For example the analysis have length 4, therefore to send a code GLI one must add a
space before or after to reach the length of 4 characters.
4-2. PATIENT TRANSMISSION
► Start communication with sequence STX<->ACK
► Send patient code................................................. (15 characters)
► Send list type for patient insertion......................... ("T" for Routine or "R" for STAT)
