The digital ouput is the serial output right and i can have to integrate this with the rs232 in the de2 board?

There are two digital output options; the RS232 option and the PWM output.
Probe the voltages on the two signals and see what their levels are. Based on that, you can decide how to interface to the DE2 board. If the RS232 output is at RS232 logic levels, then you can use the RS232 interface on the DE2 board. If the RS232 levels are really just UART logic levels, then you can use the GPIO header.
