The boost converter can be set to two different output levels. The higher one is used to give the 
battery charger adequate input voltage when the DC/DC board input comes from an external 
DC source. The lower one is set in AC/DC use to keep the boost converter enabled but passed 
by a diode and thus not switching, which minimizes the power loss. When the AC/DC voltage 
drops, the boost converter starts regulating its output and keeps the MOD voltages at a...

Battery charger
Battery charger is a Level 2 Smart Battery Charger. It communicates with the batteries and 
PMC CPU via SMBus interface. The charger acts as an SMBus slave device that responds to 
charging current and charging voltage values sent to it by a Smart Battery. 
The charger includes an input current limiting feature. In a case where the input current 
exceeds the limit, the charger reduces the output  current to keep the input within the limit. The...

2.1.10 Wireless LAN option, F-FMW 
Datex-Ohmeda Wireless Network is an extension to, or an alternative for, a wired Datex-
Ohmeda Monitor network. It provides same network services than the wired Datex-Ohmeda 
Network.
The monitor network is a local area network based on standard Ethernet technology. The 
monitor network is formed by connecting one Central and up to 32 bedside monitors together. 
The Central and the bedside monitors are connected to a 10...

DIRECT_ECG: Output signal follows first user lead (ECG1 lead) including augmented leads. If 
pace is on, there is an enhanced pacer pulse  (5 volts at 2 milliseconds) when pacemaker 
triggering is detected.
In the event of a LEAD FAIL, refer to the following:
