A system for transdermal repair of soft tissue includes an instrument comprising a proximal actuator portion, a fixed needle having a lumen and extending distally from the proximal actuator portion, and a movable needle having a lumen and extending distally from the proximal actuator portion. The system tracks an amount of data and the data units and predicts the amount of padding associated with the data units. The second semiconductor device is configured to terminate the second IO pad with a second voltage higher than the first voltage when data is received, and maintain the second IO pad and the IO channel at the second voltage when data is transmitted.
