An other resistor or a diode could be plugged in the socket. That will be now in series to the one on the board. If no resistor is needed a wire should be plugged in the sockets.\\ |
For the design two H11F1 optocoupler are used to control two output resistors. One has to trim the two potentiometer for the ideal control of the output resistor range. The two measure points Vpp and Vmin are marked on the board. One potentiometer is for the attenuation, the voltage at Vpp should be peak to peak 6V. The second potentiometer adjust the voltage level. The minimum voltage should be 3V.\\ | For the design two H11F1 optocoupler are used to control two output resistors.
