Revision D MAC 1200 resting ECG analysis system 2-25
2012250-095
Functional Description: Interfaces to Peripherals
Patient Input
The connection to the patient cable is realized with a 15-pin female sub-D
Connector, implemented on the PCB Control CS_CI directly. The mechanical
plastic housing ensures that only patient cables that have been released for use with
the MAC 1200 resting ECG analysis system system can be used.
Connector denotation: J1
Type: 15-pin sub-D, female
