Synchronize NI 6221 and absolute encoder

[Cold]

I need to synchronize my NI USB 6221 with a single turn absolute encoder in serial configuration. The encoder has 2 clocks inputs (+ and -) and I don’t know  which number of line of Digital/IO that I have to use. How can I synchronize the NI acquisition data with encoder? I´m just a student and I don´t know very much about this type of equipments ( I don´t speak English very well too) so all kind of information will be very good for me.Thanks.

Obs.: I’m using MATLAB for make the program’s interface of acquisition.
