Hi @raju,
The vision you have can be quite tricky, we have never interfaced a laboratory instrument through an Ethernet converter, but we did interface some instruments using RS232 communication with ASTM E1381-95 protocol.
Our system had two parts:
- Senaite addon: Basically it is a View helped by a cron that listens for messages from the computer software. All messages are queued and converted into a dict until the system reads the “stop” frame.
- Computer software: It was a command line interface to connect to RS-232 device and read (only read) info from the serial port. All communications sent to the LIMS without previous treatment.
You can find communication examples in the instrument documentation.
Note that at the end, our system is just reading from the analyzer and no further interaction takes place.
