4 Serial interface
The A
LIA ventilator is equipped with a serial service and production
interface.
The device can be calibrated or subjected to fault analysis. To this end, it
must be possible to connect the ventilator to a PC with terminal program.
A NULL modem cable is used for this purpose.
For communication with the ventilator, the PC interface must be
configured as follows:
Baud rate: 19200
Data bits: 8
Parity: none
Stop bits: 1
Flow control: none
After the ventilator has been switched on, the interface sends the
following initialization sequence:

During this phase, the controller runs through the stipulated algorithms
for the self-test.
