Performance Characteristics
9-6 Force FX Electrosurgical Generator C User’s Guide
Expansion Port
The 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
Expansion power (from the low voltage power supply):
+5 V (pin 6), – 12 V (pin 14), + 12 V (pin 15), and ground (pins 12 & 13)
