TMSi refa buffer problem

The hardware is TMSI refa 128 working with usb (driver is fusbi version 6.0.0.76.) windows xp+service pack3.
Using Fieldtrip and tmsidriver, I was able to collect data using the function ft_read_data via Fieldtrip real time buffer. I used
ft_read_data(C:\work\fieldtrip-20120604\fileio), this function returns a 2-D matrix of size Nchans*Nsamples for continuous data. The values are
8189887,-394150....
But the data via ft_read_data is a unexpected, it should be uV units.
I want to know how to calculate the voltage from the data collected from fieldtrip buffer.
Thank you all.
