The mains input is a wide range input from 95Vac ... 240Vac. The mains input module
contains the two primary fuses.
When replacing these fuses, the following points have to be observed:
m replacement by factory or servicing agent only!
mM disconnect mains plug!
m replacement only with the original fuses!
For the patient input, the mechanics of the patient input of the MAC500 is used, so the
patient cables of the MAC1000/CardioSmart cannot be used for the MAC1200.
A 9-pin sub-D Connector, type Mark II with 4-40 UNC inserts, with a standard configuration
of the signals TXD, RXD and GND is implemented in the consiruction of the RS-232
interface.
2.6.1 Electronic interfaces
2.6.1.1 RS-232 interface
The 9-pin sub-D Connector of the RS-232 interface is implemented on the PCB Conirol
CS Cl directly.
From Version V1.1, the remote start input pin is available on pin 8.
In MAC1200 US devices the modem supply output +8V is available on pin 6 additionally.
Connector denotation: RS232/
Type: 9-pin sub-D, female, Mark ll with 4-40 UNC inserts
The function of the individual pins is given in the following table. The definition as an
input/output is seen with reference to PCB Control CS CI.
