3The Patient Cable
The patient cable used in the PageWriter 100/200/200i/300pi family is a passive design
using no active components. The leadwires each contain a resistor designed to protect the
instrument from the energy used in defibrillation.
The cable simply conducts the analog ECG data from the patient to the ECG Front End on
the CPU Assembly Board.
