Functional Description: Interfaces to Peripherals
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.
