    Safety Safety MEDIBUS is a software protocol intended to be used by two medical devices for exchanging data and control functions via their RS 232 interfaces. This document contains device-dependent sup- ported commands and data sets, port hardware, and configurations for Dräger Intensive Care devices. For a general description of the protocol, refer to "Dräger RS 232 MEDIBUS Protocol Definition" (order-no. 9028258). Any data transmitted via the MEDIBUS interface are intended only for information purposes and should not be used to derive therapeutic decisions. Strictly follow the Instructions for Use Any use of the software protocol requires full under- standing and strict observation of the Instructions for Use of the basic device. Alarm priorities The alarm source is responsible for the priority. The priority may be variable even if from the same source. (E. g. the priority may increase the longer an alarm is pending.) Overview Data formats The underscore character used in the format col- umn in lists of measured data and alarm limits is transmitted as an ASCII "space" character (20H). A '*' ahead the format indicates that the value may be negative. In that case a '–' character will appear at the first space of the respective format. Be aware that in a small number of cases the used format for a certain item may be different! Alarm phrases Some alarm phrases contain abbreviations as fol- lows: ASCII short form Meaning $& "# '@ LOW HIGH ALARM Software Protocol for Dräger Intensive Care Devices 3
