25.3.5 Table of Current Alarm Condition Codes.
25.4 RS232 Connection Settings and
Testing Data Output
Connect a standard serial cable from the ventilator
to the test computer. Turn on the ventilator and
allow it to enter Ventilation Off mode. Open the
Hyper Terminal for Windows or the terminal
emulator for other operating systems, (Settings:
COM1, 19200 bps, 8 Data bits, Parity None, 1 stop
bit, Flow None or No handshake). Turn on the
ventilator, the hyper terminal should show that
comma delimited data is being sent.
