12 Mechanical components
The main mechanical components comprise the upper and lower shell of the MAC1200
The lower shell serves as a basic unit to receive the following assemblies:
mM Line power input module with fuse
m Switching power supply
m NC Battery
m PCB NC Battery Charge
m PCB Control CS Ci
m PCB Modem Supply CS M
m Graphics display
m Thermal printing unit
m 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 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 iocated directly on the PCB Control CS CI.
