Mechanical components

The main mechanical components comprise the upper and lower shell of the
MAC1100/1200.
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
PCB Modem Supply CS_M
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 MAC1100/1200 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 located directly on the PCB Control CS_CI.
