Device that has a message to send and that initiates the transmission process.
Upload
Data transmitted from STA Satellite< to the host computer.
Receiver
Device that responds to the sender.
Download
Data transmitted from the host computer to the STA Satellite< .
Frame
All framing required for transmission of data. This framing will include:
or [C1] [C2] .
Frame number (Fn)
Frame number allows the receiver to distinguish between new and retransmitted frames. ASCII digit ranging from 0 to 7. The frame number beginsat 1with the first frame of transferi phase. It is incremented by one for every new frame transmitted. After 7, the frame number rolls over to 0, and continues in this fashion.
Message
A group of records that begins with a Header record, and ends with a Terminator record.
Record
Thisisthe DATA as described withinthe frame. If the DATA islonger than240characters, then it must be split into two parts an sent in two frames. The intermediate frame will use the [ ETB ] character and the ending frame will use the [ETX] character. For our application: -
in download mode, a frame may include several records, indeed a message.
-
in upload mode, one frame is used for sending each record.
List of selected records (See description, chapter 6 of this document): -
- H (Header),
-
- P (Patient),
-
- O (Order),

press the ECS key to bring up to the Main Menu.
-
select the Setup menu, and select the Global Option sub-menu from this menu.
Thismenu in the STA Satellite< program is used, amongst other things, to program the communication parameters between an STA Satellite< and a host computer. The access is restricted by a code system.
4.2 Description of parameters Parameters for which there is a multiple choice are shown in white (to make the different selcetions, use the DELETE key), and those with free entry in blue.
Staion number: number by which the host computer identifies the STA Satellite< .
Maximum=99.
Baud rate : chosen transmission speed : 300, 600, 1200, 2400, 4800, 9600 Baud.
Parity : type of parity chosen : none, even or odd.
Number of Data Bits : 7 or 8
Number of Stop Bits : 1 or 2
Number of On Error Retries : number of times the STA Satellite< returns the frame when it
receives a character different from or . In accordance with the Standard E 1381-91, this number has to be set to 6.
Check patient Data :
Possible choices : - YES, when the working list is remotely loaded, the STA Satellite< records 4 patient information
fields (a maximum of 38 characters for processing and control) and the operator may check them. These 38 characters are defined on the STA Satellite< as follows : Information 1
16 characters maximum
Information 2
12 characters maximum
Information 3
6 characters maximum
Information 4
4 characters maximum
Total -

5 Exchange Protocol 5.1 Definition of line modules on STA Satellite< -
Idle = no communication in progress
- Tx = transmission by STA Satellite< -
Rx = reception by STA Satellite<
5.2 Definition of phases of communication ASTM communication is composed of three phases : -
Establishment phase : line picked up by the host computer or the STA Satellite<.
- Transfer phase : transmission of the different records which compose the message (see Records
Definitions, chapter 6). - Termination phase : the line is released.
5.3 Host computer to STA Satellite< exchanges Responses of STA Satellite< to characters transmitted by the host computer: 1
Reception of the character transmitted by the host computer If the STA Satellite< is in the Idle mode,it transmits an character (06h) and then changes to reception line mode Rx . If after 30 seconds, no character is received, the STA Satellite< returns to the Idle line mode.
2
Reception of the character transmitted by the host computer If the STA Satellite< is in the Rx reception line mode and a header record has been received, the STA Satellite< then changes to Idle line mode (releasing the line). The STA Satellite< analyses the records received. If the STA Satellite< is in Tx transmission line mode, the character is considered as an acknowledgement (seechapter 5.4.2).
3
Reception of other characters transmitted by the host computer The STA Satellite< proceeds to enter the characters received. After entering a complete frame the STA Satellite< verifies the checksum. If this is satisfactory, the STA Satellite< acknowledges by returning an character (06h). If not, a character (15h) is returned. Followingthe upload of the characters or , if after 30 seconds, no character is received, then the STA Satellite< returns to the Idle line mode.

5.4 STA Satellite< to host computer exchanges
5.4.1
Setting up phase If the line mode is Idle, the STA Satellite< sends an character (enquiry). Possible responses from the host computer : 1
Transmission of an character by the host computer The STA Satellite< changes to Tx transmission line mode and initiates the frame transfer phase if it is in normal mode, or initiates the termination phase (transmission of an [EOT] character) if it is in the line test mode.
2
Transmission of an character by the host computer The STA Satellite< waits 5 seconds and then returns an character.
3
Transmission of other characters by the host computer The STA Satellite< waits 10 secondsand then returns to an character. When the value "Number of Retries On Error" defined in theGlobal Options menu (seechapter4) is achieved, the STA Satellite< changes to termination phase (transmission of an character) and displays an error message.
4
No response from the host computer The STA Satellite< waits 15 seconds, and then changes to termination phase (transmission of an character) and displays an error message.
5.4.2 Transfer phase (STA Satellite< to host computer) Transmission of the first record by the STA Satellite<. Possible responses from the host computer : 1
Transmission of the or characters by the host computer The STA Satellite< sends the next frame.
The STA Satellite< considers the character as an acknowledgement character and continues to transmit frames.

Transmission of other characters by the host computer
The STA Satellite< waits 10seconds before returningthe frame. If the number of «On Error Retries» is superior to the one defined in the Global Options menu (see chapter 4), the STA Satellite< changes to termination phase (transmission of an character) and displays an error message. 3
No response from the host computer
The STA Satellite< waits 15 seconds and then changes to termmination phase (trasnmission of an character) and displays an error message.
5.4.3 Termination phase (STA Satellite< to the host computer) The STA Satellite< transmits an and does not wait for any returned character. The STA Satellite< changes to Idle line mode.

This message "Working List Return" can also be used to add tests, to return tests or to modify the priority code. To add tests, Test Order record has to include the local codes of tests to be added. To rerun tests, it has to include the local codes of the teststo be rerun.And, to modify onlythe priority code for a patient file already present in the STA Satellite< Working File, short Test Order records can be used : - example to modify priority code from "routine" to "stat" : O | 1| ESSAI| | | S.
