The Basics: Mechanical Components
Mechanical Components
The main mechanical components comprise the upper and lower shell of the MAC
1200 resting ECG analysis system. The lower shell serves as a basic unit to receive
the following assemblies.
Line power input module with fuse
Switching power supply
NC Battery
PCB NC Battery Charge
PCB Control CS_CI
Graphics display
Thermal printing unit
Paper container
The upper shell accommodates the keypad, which is connected to the PCB Control
CS_CI via a 26-pin connector.
The MAC 1200 resting ECG analysis system can be opened by releasing 5 screws
at the bottom of the lower shell, opening the paper flap and lifting up the upper shell
a little bit to remove the keypad cable from the PCB Control CS_CI. The upper shell
then can be removed completely.
To replace the NC Battery, the battery flap at the bottom of the lower shell must first
be unlocked with a screw-driver before it can be removed.
The 15-pin input connector to connect the patient cable and the 9-pin connector for
the RS-232 interface are located directly on the PCB Control CS_CI.
