2.5 Satellite Module Rack
The satellite module rack (SMR) is independent of the patient monitor, provides 8 slots for
mounting parameter modules. It has the following features:
It allows a parameter module to be plugged and unplugged with the patient monitor on.
This allows function extension and patient transfer.
It does not have its own power. It introduces 12 V DC from the patient monitor and then
supplies power to each parameter module via the contact screw.
It accomplishes communications protocol conversions between the patient monitor and
each parameter module, provides infrared communications for parameter modules, and
is responsible for detecting infrared communications malfunction for each parameter
module.
The following diagram shows the structure of the SMR.
