    Hi Fred,

    Are you referring to the SPI signals? The EVM should have some test points on the SPI lines, TP9, TP15, and TP16. You could take the signals off one of the EVMs and hook it them up to the other three through these test points. The zero ohm jumpers, R103, R104, R105, should be removed to separate the USB chip from the SPI signals.

    See the schematic by downloading the design package from the product page: http://www.ti.com/tool/ads4149evm
