Signal Name

Description

ACT_REQ_HAND_A

This is an input signal from the Hand A request sense
circuit. Hand A refers to the Cut button on the hand-
piece. This signal is generated by a colpitts oscillator
located on the main board. When an activation request is
made, this oscillator become a logic 1 (5 VDC) signal.

ACT_REQ_HAND_B

This is an input signal from the Hand B request sense
circuit. Hand B refers to the Coag button on the
handpiece. This signal is generated by a colpitts oscillator
located on the main board.

When an activation request is made, this oscillator
becomes a logic 1 (5 VDC) signal.

ACT_REQ_FOOT_A

This is an input signal from the Foot A request sense
circuit. Foot A refers to the Cut pedal on the footswitch.
This signal is generated by a colpitts oscillator located on
the main board.

When an activation request is made, this oscillator
becomes a logic 1 (5 VDC) signal.

ACT_REQ_FOOT_B

This is an input signal from the Foot B request sense
circuit. Foot B refers to the Coag pedal on the footswitch.
This signal is generated by a colpitts oscillator located on
the main board.

When an activation request is made, this oscillator
becomes a logic 1 (5 VDC) signal.
