Understanding the datasheet of a fluorescent display to drive with an Arduino

I recently got a 2x20 character fluorescent display (Futaba M202MD07HB) for free, and I was hoping to make some use of it. I thought to use an Arduino to write in the inputs to make it easier to control. I have looked at the datasheet, but I'm not really sure how I'm supposed to write in parallel inputs - I understand that I need to put pins D0-D7 on high and low to select the character, but I don't see how I actually put those values onto the display (using a clock pin or something like that).

I have a feeling that the information is all on the datasheet, but I'm just too inexperienced to understand it. Can someone who has the experience help me out or point me in the right direction? The datasheet can be found at: http://www.datasheetarchive.com/dl/76254b0f2bce8991013323093e1ac649308f27/O/m202md07h

You can select either parallel or serial. See page 11 & 12. If using parallel, per timing diagram on page 11, assert a low on the SEL pin, place the data on the 8 data pins, then assert Write low to strobe the data in.
In serial you just send the data byte by a serial channel, RS232 style to the RXD pin . (start bit, 8 data bits, Stop bit). Table 10 at the top of page 10 tells how to select the baud rate.

Whichever interface you use be aware that VFD displays consume a lot more power than LCD so do not connect it to the Arduino +5. The reason for the power draw is that in order for the fluorescent pixels to light up they draw electrons from a heated filament strung across the elements. there are actually 6 or 8 of these and can be seen glowing slightly in a darkened room. These filaments are also very sensitive to mechanical shock and will break, causing faded characters.
The data sheet indicates that the display will require at least 1 Amp at 5 volts.

Thanks for the help and quick response - the data sheet makes a lot more sense now! For the power draw problem I was planning on using transistors so that I could run a separate 5V power supply to the display.
