In 

M-ETPR module

,

 

there are two small boards, the ECG input board and the 2P input board

attached to the front panel of the module. The front panel has five connectors and four keys. The

connectors are two for temperature measurement, two for invasive blood pressure measurement,

and one for ECG

 

measurement. The keys are for ECG lead, Start Wedge, P1 zero, and P2 zero.

In 

M-ESTR module

, there are two small boards: the S input board and the ECG input board,

attached to the front panel of the module. The front panel has four connectors and one key. The

Front panel of M-NESTPR

The 

M-NESTPR, M-NETPR, and M-NESTR

 

modules 

contain three main PC boards, the STP board,

the ECG board, and the NIBP board. They work independently. Each of these has their own

processor and software EPROM.
The 

M-NE12STPR, M-NE12TPR, and M-NE12STR

 contain three main PC boards, The STP board,

the ECG board and the NIBP board. They work independently. Each of them has their own

processor. The STP board and NIBP board have software EPROM. In the ECG board the software is

in flash memory. The STP and NIBP boards are the same as in M-NESTPR module but the ECG

board and ECG input board are different.
