For AD3542RFMCZ. why green led is not turning on which indicates correct power up?

This LED is driven from the controller, not from the power rails. It will not light up if not using SDP-H1 with ACE SW.

IF I am using the 12 V to +12V_FMC at pin 1 of connector P5 and 1.8 v to POWER_ON_FMC at pin 2 pin 1 of connector P5.

To the fpga to interface with Evaluation kit AD3542R. 

why vout give near about  -1v? CH0_CH1_OUTPUT_RANGE is 00000001.

it should be 0 to 5 volt. IF I CHANGE THE OUTPUT VOLTAGE RANGE vout give near about  -1v why? 

FOR DAC INTIALIZATION REG:

REFERENCE CONFIG (0X15), TRANSFER_REGISTER  (0X0F), INTERFACE_CONFIG_A(0X00),INTERFACE_CONFIG_B (0X01), CH0_DAC_16B(0x29), CH0_DAC_16B(0x2A)

The DAC register is at zero scale after reset, but the DAC is in power down mode until the first code is written. IOUT and VCM are floating and its voltage depends on the configuration of the output amplifier. Typically it is a few mV from GND if the amplifier is supplied symmetrically.

Changing the output range register on the fly also causes the DAC to output a different voltage depending on the code that is loaded.
