4-6. VARIABLE SERIAL PROTOCOL

Introduction

The variable serial protocol has been designed to provide the user with possibility to

personalize the transmitted and received data from the analyzer.

The user can transmit or receive in addition to preset data (patient code, analysis code,

results etc.), also the simple text strings and/or characters in order to meet the personal

requirements.

Not only the user can decide to send or receive numerical information (for example

number of tests) not as single byte but as a preset numerical string or vice versa.

For example the user can decide to receive something like:

"Initiate analysis data"

"End analysis data"

Where the phrases "Initiate analysis data" and "End analysis data" do not refer to any

preset data by the analyzer but serve only for monitoring communication process (can be

useful for inserting specific markers on those programs which obtain information from text

files).

It is obvious that the protocol of initiation and end of communication, the commands for

the request of report, and the analyzer responses in case of error or success remain

identical to the usual preset serial communication.

NOTE:

a) If a check-sum is omitted in a communication then the analyzer will not control it.

b) The following numbers have been used to represent the error codes relevant to sending a

patient to the analyzer as regards the parameters not part of the standard serial

communication:

Error Code Description

1 Number of invalid analysis

2 Invalid Data (not through variables)

3 Invalid Data (through variables)

An analysis variable is outside the SET BEGIN/END relative to

the analysis
