Interfaces to Peripherals

Revision D
Functional Description: Interfaces to Peripherals
The MAC 1200 resting ECG analysis system has only 3 interfaces for peripherals.

Mains input

Patient input
 RS-232 interface
The mains input interface on the device is a 3-pin standard cold appliance socket
connection, which is integrated into the mains input module. Connection to the
mains is effected via a 3-pin power cord with a non-fused earth conductor.
The mains input is a wide range input from 95 Vac ... 240 Vac. The mains input
module contains the two primary fuses.
When replacing these fuses, the following points need to be observed.

Replacement by factory or servicing agent only.

Disconnect mains plug.

Replacement only with the original fuses.
For the patient input, the mechanics of the patient input of the MAC 500 is used, so
the patient cables of the MAC 1000/CardioSmart cannot be used for the MAC
1200 resting ECG analysis system.
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
construction of the RS-232 interface.
