I am going to take a wild guess here and say that is a 595 display just like the last guy. So it is going to want 64 bits of data for the 64 segments. Why not read up on ShiftOut and sent it FFFFFFFFFFFFFFFF (64 1 bits). I bet it illuminates all the segments. Then work it out which bit maps to what segment.
See "For accompanying circuit, see the tutorial on controlling a 74HC595 shift register." about a page down.
Set latchPin to the Arduino pin you have RCK connected to.
Set clockPin to the Arduino pin you have SCK connected to.
Set dataPin to the Arduino pin you have DIO connected to.
