Configuration Command Responses
Configuration responses are data packets sent by the Module to the host at programmed
intervals. A single host measurement or auto run mode command initiates unsolicited
transmission of CO
2
waveform and breath data packets. The programmed interval between
packets is either defined by the host via a configuration command or the host may use the default
setting.
