Performance Characteristics
Technical Specifications
Force FX Electrosurgical Generator C Service Manual 3-7
Expansion Port
Low Frequency (50–60 Hz) Leakage Current
High Frequency (RF) Leakage Current
15-pin connector;
supports the
following signals
• Pin 2–isolated transmit
(serial data output transmit line)
• Pin 3–isolated receive
(serial data input receive line)
• Pin 5–isolated ground
(reference for transmit and receive)
• Pin 9–RF disable: input signal which, when activated
by an external device, disables active RF output
• Pin 10–RF current: output signal proportional to
active RF current
• Pin 11–RF voltage: output signal proportional to
active RF voltage.
