2.5 SMR
The satellite module rack (SMR) is independent of the patient monitor. It 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 supply. It is run by 12 V DC supplied by the patient
monitor and then supplies power supply to each parameter module via the contact
screws.
„ It implements communication 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.
