DAC81408EVM: output always 0v

Part Number: DAC81408EVM

Hello  Team

I'm trying to control the DAV81408EVM with USB2ANY interface adapter and GUI from DAC81408EVM software downloaded for the TI website.

I use internal 2.5 V reference, Supplying the board with VDD/VAA = 5 V, VCC = 12 V VSS = -12 V and VIO = 3.3V (supplied from the USB2ANY adapter)

1. the jumper settings are follows.

2. DEVICE_ID  reads value 0X0A60.

2.STATUS   reads value  0x0008.

3.SPICONFIG reads value 0x0A84.

in DAC81408 page, changed DACOUT,  its always seems zero.
