    2.3.1 The Configuration of Voltage Output Reference Source Setting The reference voltage source of PISO-DA2‘s D/A converter can be provided by the internal generator or external reference voltage, which is coming from the connector CN1 and CN2. The setting of the reference sources for Channel 1 and Channel 2 are controlled by the jumper JP6 and JP10 respectively, as depicted in the following table.
  • Page 12 If the internal reference voltage source is selected to implement the analog output of the D/A board, then the reference voltage level must be set as the internal voltage source -5V or -10V, which is precision voltage source provided by PISO-DA2, by jumper JP4 (Channel 1) and JP8 (Channel 2).
  • Page 13 Output Range Setting After the configuration of reference voltage source, the practical voltage output range of PISO-DA2 can be regulated as either Bipolar or Unipolar by jumper JP5 and JP9. The detail setting is demonstrated in Table 2.5. For example, if the jumper JP4 and JP5 are set as -5V and Unipolar respectively, then the range of voltage output is 0~5V for channel 1.
