I followed the instructions from instructables to hook the display up to an Arduino Mega.
http://www.instructables.com/id/Arduino-and-the-Noritake-24x6-VFD-Module-Vacuum-Fl/

Pin 1 VCC to 5 Volts
Pin 2 SIN to Digital 3
Pin 3 GND to GND
Pin 4 SBUSY to Digital 5
Pin 5 NC not connected
Pin 6 RESET to Digital 7

A very important thing: I am using a power supply otherwise the display doesn't work.
The power supply I am using is 7.5V and 1.06 A

code from http://www.noritake-elec.com/arduino-code-library-quick-start-guide.php :

#include <CUY_Interface.h>
#include <CUY_Parallel.h>
#include <CUY_Serial_Async.h>
#include <CUY_Serial_Sync.h>
#include <Noritake_VFD_CUY.h>

// Uncomment one of the communication interfaces below.

CUY_Serial_Async interface(38400,3, 5, 7); // SIN,BUSY,RESET

Noritake_VFD_CUY vfd;

void setup() {
_delay_ms(500);// wait for device to power up
vfd.begin(20, 2);// 20x2 character module
vfd.interface(interface); // select which interface to use
// Enter the model class
// E.g. Y1A for CU24043-Y1A
// Applicable model classes:
// Y1A
// YX1A
// Y100
// YX100
vfd.isModelClass(Y100);
vfd.CUY_init();// initialize module
vfd.print("Hello Zach!"); // print Noritake on the first line
}

void loop() {
}
