ADVIA 2120 Hematology System 1
Purpose
This document describes the bidirectional communication link between the Data Manager software in use on the
ADVIA 2120 Hematology System and a laboratory information system (Host Computer). This bidirectional link is
commonly known as the Host Spec. 79 protocol.
This document is intended for the Information Systems (IS) professional responsible for connecting the Data
Manager and your Host Computer. Please contact Siemens Customer Service if you need additional information.
Overview
The communication link enables workorders to be transmitted from the Host Computer to the Data Manager and
results to be transmitted from the Data Manager to the Host Computer.
There are two mutually exclusive modes by which workorders can be transmitted: downloading mode and query
mode. Use the HOST WORKORDERS TRANSFER MODE parameter on the
Customer Parameters window to
select the desired mode. See Figure 2.
` Downloading workorder mode (D mode)
The Host Computer can download workorders identified by a sample identification number (Sid#) whenever it is
the Master* device. Workorders can be downloaded in any sequence. When the Data Manager receives a request
by Sid# or R&P# from the analyzer, it searches its own database for the matching workorder. If none is found, the
default profile is used. The Data Manager will not try to get the workorder from the Host Computer.
` Query workorder mode (Q mode)
The Host Computer does not download a workorder until one is requested by the Data Manager. When the Data
Manager receives a request based on the Sid# from the analyzer, it searches its own database for the matching
workorder. If none is found, the Data Manager sends a request based on the Sid# to the Host Computer. The
R&P# is not used in the Query mode. If the matching workorder is available, the Host Computer downloads it to
the Data Manager. If none exists, the Data Manager is informed and the default profile is used.
` Full Query workorder mode (F mode)
The Host Computer does not download a workorder until one is requested by the Data Manager. When the Data
Manager receives a request based on the Sid# from the analyzer, the Data Manager sends a request based on the
Sid# to the Host Computer. The R&P# is not used in the Full Query mode. If the matching workorder is available,
the Host Computer downloads it to the Data Manager. If none exists, the Data Manager is informed and the
default profile is used. The Data Manager database is never consulted. When using F mode, the customer
parameter
Replace sample in complete by workorder must be set =Y.
The QUERY TO HOST TIME-OUT VALUE parameter on the
Customer Parameters window determines how
long the Data Manager will wait for a response from the Host Computer. If the workorder is not received before
the time out is exceeded, the Data Manager sends the analyzer a message that no workorder exists and the default
profile is used. If the workorder is sent after the QUERY TO HOST TIME-OUT VALUE but before the
Host_Watchdog parameter (see page 49), the workorder is created and stored in the Data Manager database. For
this reason, the QUERY TO HOST TIME-OUT VALUE parameter must be less than the Host_Watchdog
parameter.
NOTE
Regardless of the HOST WORKORDERS TRANSFER MODE parameter selection, the system uses the
Downloading Workorder mode if the Position Mode option is selected in the
Routine Parameters window.
* The device (Host Computer or Data Manager) with control of the communication line is called the “Master” device and is
expected to initiate each exchange of messages.
