This is and output signal from the system logic that generates a 62.5 kHz square wave.
This signal is used by the NEM circuit.
This is an output signal from the system logic that controls an analog switched. This
signal is used by the NEM circuit to change the analog signal sent to the NEM A/D.
This is an output signal from the system logic that controls an analog switched. This
signal is used by the NEM circuit to change the analog signal sent to the NEM A/D.
Reserved
This is an output signal from the system logic that generates the activation tones for all
modes of operation. A 1kHz square wave is generated whenever Cut I, Cut II or Blend
modes are activated. A 2Khz square wave is generated when the Coagulation,
Fulguration or Bipolar modes are activated. This signal is used by the audio circuit.
This is and output signal from the system logic that generates a 2 kHz / 1kHz square
wave for activating the alarm siren. This signal is used by the audio circuit.
This is an output signal from the system logic that controls the accessory relay on the
back panel.
This is an output signal from the system logic that controls the relays to allow fulguration
coagulation output.
This is an output signal from the system logic that controls the relays to allow output to
be present at the monopolar foot controlled receptacle.
This is an output signal from the system logic that controls the relays to allow output to
be present at the monopolar handpiece receptacle.
This is an output signal from the system logic that controls the relays to allow output to
be present at the bipolar receptacle.
This is an output signal from the system logic that controls the relays to allow output to
be present at the foot control receptacle.
This is an output signal from the system logic that controls the relays to allow output to
be present at the monopolar return receptacle.
This is an output signal from the system logic that turns on the power factor correction
circuit during activation of the unit.
