TLV320DAC3203EVM-K: Standalone operation settings

Part Number: TLV320DAC3203EVM-K

Using TLV320DAC3203EVM-K connected to the USB-MODEVM, I can setup the device using I2C

P12-20 SDA

P12-18 Ground

P12-16 SCL

and it functions correctly.  If I disconnect the USB-MODEVM and add the connections as follows:

P23-3 +5v

P22-17 MCLK (19.2Mhz)

It will not respond to I2C queries.  Do I need different switch settings, jumpers, or other signals?
