NEM_CLK_GEN
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.
NEM_PAD_SENSE_EN
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.
NEM_TEMP_SENSE_EN
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.
SENS_RANGE Reserved
AUD_DRV
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.
ALARM_DRV
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.
AUX_RLY
This is an output signal from the system logic that controls the accessory relay on the
back panel.
FULG_EN
This is an output signal from the system logic that controls the relays to allow fulguration
coagulation output.
MONO_EN
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.
HANDLE_EN
This is an output signal from the system logic that controls the relays to allow output to
be present at the monopolar handpiece receptacle.
BIPOLAR_EN
This is an output signal from the system logic that controls the relays to allow output to
be present at the bipolar receptacle.
FOOTC_EN
This is an output signal from the system logic that controls the relays to allow output to
be present at the foot control receptacle.
RETPAD_EN
This is an output signal from the system logic that controls the relays to allow output to
be present at the monopolar return receptacle.
PFC_ON
This is an output signal from the system logic that turns on the power factor correction
circuit during activation of the unit.
