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 -5 V or -10 V, which is precision voltage source provided
by PISO-DA2/DA2U, by jumper JP4 (Channel 1) and JP8 (Channel 2). The
detail setting method is illustrated as Table 2-4. The default setting is -5 V.
