Noritake VFD SCK-3900-512X32H-01

51 posts in this topic

Thought I'd start a new topic for this since a few of us are getting one.

 

Poking around their website, it appears http://noritake-vfd.com/gu512x32h-3900b.aspx supersedes the units being given away, which is GU512x32h-3900. That display is what's on the Christmas tree at http://noritake-vfd.com landing page and these kits: http://noritake-vfd.com/networkdisplaykit.aspx and http://noritake-vfd.com/messageselectorkit.aspx.

 

Reading through datasheets and sites the unit has RS232 and parallel interfaces, 4 bit input and 8 bit GPIO that can respond to or activate external components. It requires both 5v and 24v, has normal command and graphic DMA modes, supports macros in flash that can run unsupervised / without external MCU, and 32K + 64K(*4) flash rom.

 

I'm thinking this might be a candidate to include in the dashboard on my motorcycle if it's not too large, and I can coax 24v from the bike somehow.

Just received UPS email saying it's shipping, 1.4 pounds, and scheduled delivery 12/24/2013. ::

Left Illinois at 7:34 pm, their time.

 

Coming from Illinois; can't imagine it taking more than 3-4 days to get here, actually.

Just received mine.  Easily the largest display I have ever handled. :smile:

 

They included a single fact sheet with a number of PDFs referenced for the unit.  It is stated that the base model # is GU512X32H-3703 which is hardware/software compatible with the GU512X32H-3900 (minus the "B" at the end which, as @@abecedarian mentioned in his initial post, appears to be the newer model).  It took a bit to find the web page that referenced the PDFs on the fact sheet.  This page has most of them:

Still searching for the last one of the referenced PDF's.  Will post if I find it.

Also have one of these on the way.  Thanks for tracking down the data sheets.  Will be interesting to see what this crowd comes up with.

This is what I've grabbed so far- note account / login may be required:

 

GUD10K:http://www.noritake-elec.com/gud10k.html

Windows-based software allows you to use the RS232 adapter kit to program / record "macros" for the display to run.

 

International font tables: http://www.noritake-elec.com/form.php/s-gu3xxxintfont_e03.pdf

Macro spec: http://www.noritake-elec.com/form.php/s-gu3xxxpmacro_e03.pdf

Software spec: http://www.noritake-elec.com/form.php/s-gu512x32dot-39xxsoft_e02.pdf

Hardware spec: http://www.noritake-elec.com/form.php/s-gu512x32h-3xxxhard_e04.pdf

 

GU3000 series web page: http://www.noritake-elec.com/3000_series.htm

The page isn't that intuitive, but if you scroll down to the tables listing the models / part numbers, the columns titled "Interface", "Datasheet", "Font Tables" and "Tools & Software", the text in those are hyperlinks to documents.

Looking at things though, I'm confused a bit.

 

They sell an "adapter kit", near bottom of page here that is RS232 and power for the display, but it only outputs 5v @ 3A, so maybe the display has an internal step-up to 24v if 5v is used, or can operate on 24v by itself if available?

Might just have an internal step-up. The existing 128x32 or whatever kit we just got included some form of boost converter onboard. Probably why it uses so much darned power...

Probably correct. It's just it says 5v & 24v, not 5v OR 24v.

I guess we'll no more soon. :D

@@spirilis Here are some pictures of the front and back.  Front pic is a little blurry but there isn't much to see on the front side.  The AA battery is there for scale.

 

@@abecedarian looking at the datasheet it doesn't appear there is a 5V only power option.  Perhaps that was one of the improvements with the "B" model.  Max total power dissipation (5V and 24V) is about 9W (6.9W typical) with all dots on and about 8W (5.4W typical) with all dots off. In addition, it looks like the 24V supply needs to be able to handle 2x the rated datasheet value (inrush current) so we will need 700ma+ for the 24V supply. Or a big cap. :smile:

@@dubnet - Yes, the documentation is vague on it. Other models, like the GU256x64-3900B are 5v only, so it doesn't seem to be a physical requirement for 24v given that one would have the same pixel count. There are mentions of being able to chain displays so maybe this is where the 24v comes in? There's not much documentation out there on these things other than the datasheets and a few sparsely commented projects using them.

Sweet! Just received mine today out of the blue, and later an email from Noritake with a link to the datasheet. No time right now to play but that is indeed an impressively big display! Can't wait to fire it up. If we do have to produce 24V then I'd like to consider a boost circuit based around a 12VDC input for versatility sake... could be a boosterpack too. I have a 12V@6A bench supply and small 1.5A 5V switching buck converters that work in an LM7805 pinout off 7-36V in.

Weird, HW guide mentions the GU512X32H-3xx0 and 3xx1 models, but mine is a GU512X32H-3703 model.  Guess I'll have to dig deeper into that later.

 

From that manual though, it looks like it has a whole complement of RS232 serial (think it's TTL level) and Parallel (like HD44780 style pins).  CN6 is the power header with VCC1=5V and VCC2=24V.

Just brainstorming, I may have two 12V lead acid batteries hanging around that I can connect in series assuming the voltage is within range.

Ah sweet, just confirmed that too.  RS232 are indeed RS232 levels, so no go there, gotta use the parallel interface.  Would be a good idea to have 5V level shifters in there when eventually designing a boosterpack of sorts.

Lol man these things are expensive M-F'ers!!

 

"Sample price" is $118 for this, but Mouser sells it for $365.06...

Another one, the GU128x128D, looks pretty snazzy with just DC5V input but Digikey sells it for... $164.58 (Noritake's own "Sample Price" is $112.40)

 

Alas, lots of tech inside them I guess and they do look pretty nice.  Can't wait to light up this 512x32.  This one has to have a legitimate project behind it... probably with a custom wood frame plus Tiva LP+CC3000 or something to do it justice.

Checked out TI's WEBENCH application for kicks... it pointed me to the TPS55340, which then also suggested TPS61175 for narrower Vin (don't need 40Vin).

Datasheet: http://www.ti.com/lit/ds/symlink/tps61175.pdf

Might make a good boost converter for supplying our 24V.  Works with 2.9Vin at the minimum though, so with a beefy 5V rail I bet it could enable 5V operation for the whole circuit.  Not likely to get that kind of power from the LaunchPad though so having a 12Vin target voltage is a good choice IMO for versatility of power sources.
