Jumper Selection
Jumper P1
Enables you to choose the modes of DAC, i.e. dual port and interleaved mode. Place the jumper in
position 1-2 to select dual port mode and position 2-3 to select interleaved mode.
Jumper P2
Enables you to choose the Gain control modes of DAC, i.e. independent and master/slave mode. Place
the jumper in position 1-2 to select master/slave mode and position 2-3 to select independent mode.
