3) Using the Oscillator Circuit Bare Board

To use this product at a frequency you like, build a desired oscillator circuit on the included OSC-2 oscillator circuit

bare board. Figure 2.20 shows an external view of the OSC-2 oscillator circuit bare board and the connector pin

locations. Figure 2.21 shows the circuitry of the oscillator circuit bare board OSC-2. Use the number of oscillator

circuits recommended by the oscillator manufacturer.

J1-4: GND

J1-3: Oscillation output
