SPI Communication with EVAL AD5755-1

Hello, I'm trying to communicate with an AD5755-1 using the EVAL board.  I've hooked up my SPI connections to the appropriate pins, but I can't replicate the activity when I use the EVAL board software.  I'm using an arduino with 

SPI.beginTransaction( SPISettings( 500000, MSBFIRST, SPI_MODE3 ) );

Here is my current input/output streams.

Starting
Chip: 00 CS_PIN:25
Software Reset
Sending: {1C, 85, 55};
Received: {E0, 80, 0};
DCDC register write
Sending: {1C, 60, 7};
Received: {0, 80, 0};
Main Control Register Write (16mA)
Sending: {1C, 22, 0};
Received: {0, 80, 0};
read main control register (0200 expected)
Sending: {99, 0, 0};
Received: {0, 0, 0};
Main Control Register Write (8mA)
Sending: {1C, 22, 40};
Received: {0, 80, 0};
read main control register (0000 expected)
Sending: {99, 0, 0};
Received: {0, 0, 0};
read main control register (0000 expected)
Sending: {99, 0, 0};
Received: {0, 0, 0};
gain register
Read Gain Register
Sending: {88, 0, 0};
Received: {0, 0, 0};
NOP CMD
Sending: {1C, E0, 0};
Received: {0, 80, 0};

Please advise on how to address this communication issue.  I've tried a bunch of different things, but I just can't replicate the EVAL software results.  Is there a problem in my setup protocols?
