About

If you wish unidirectional communication with medical equipment using ASTM protocol this might be useful

It handles both RS232 (COM Port, ttyS0 etc ) and TCP connections via LAN/wifi

It is tested with

Erba biochemistry analysers (XL-640)
Note: Erba XL-640 with Windows-XP have problem with resources. Use Windows 7 or above
ElitePro Coagulation analyser
It must work with any analyser following ASTM protocol

prerequisites

• Linux ( Tested in debian, but must work with any)
• Python3 +
• Some python 3 libraries like sys,logging, signal time,datetime,socket,serial
• Most libraries are deault installation with python in Linux
• See log file for missing libraries

This project have astm_general.py file as sole code

• The program simply sends ACK on receipt of ENQ and LF from equipment
• The data received (from ENQ to EOT ) is saved in a file (see below)
• It is up to user to decide what to do with this data (e.g. database interfacing)
• manual edit of file required for following
  • to select the mode (tty or tcp)
  • to select tty device (if tty mode)
  • to select ip and port (if tcp mode)
  • to specify folder for saving data files
  • to specify file where log will be stored
• make file executable

chmod +x astm_general.py

• run script
• use inotifywait to see files being created
• see log file for error

What Next

• create service to run at boot time (I am planning to add its example)
• create mysql support for database insertion
• program for bidirectional service
