Intel Desktop Board DN2800MT Build

Is it 2mm pitch at both ends?
You may be able to remove the pins from the 2mm pitch connector block and put them into a similar 0.1" block. Fiddly though.
Steve
Jupp it is 2mm in both ends of the cable, think i might get one of this and fiddle with that:
http://uk.rs-online.com/web/p/headers-pcb-receptacles/6706561/ NOt sure yet but will look around on RS's shop to see if i find something more convenient
But i am going to check out the LCD on my old x500 after work, because i like the LCD color in that one more than the x550e LCD.. ;D -
Found this:

-
That could work.
You are going to have to check the connections somehow though.Steve

You will need to check the pin-out on the Firebox side. I'm almost certain that it doesn't line up pin for pin with the header on the Intel board. TBH, it is probably easier to just hack a cheapo HD44780 LCD off ebay into that case.

Tnx again for the pointer to the LCD, you really know your hardware. ;)
IF the Firebox LCD give me alot of problems, i then will replace it with a cheap HD44780.
But will give it a goooood go to get the firebox one to work because i am trying to reuse as much hardware as i can, and i do like a good challenge when it comes to make things just work.. 8) -

If anyone has the pinout for either the LCD or the original board, then it wouldn't be much of a problem. Otherwise, I reckon a logic analyzer to sniff on the pins would be needed.

I'm on a similar route; I want to build a NAS with the DN2800MT. I'm very interested in your experiences. I haven't ordered yet as I need time to build it. I also need 3 x LAN: 1 x LAN, 1 x WAN and 1 for WiFi.
All dual port NIC's I came across have a x2 or a x4 card size. I believe these card would work in a x1 slot but it just doesn't fit.
I selected these PCIe risers to convert from the x1 slot on the board to the x2 for the card: http://www.ameri-rack.com/ARC1-PEX16_m.htmlBest regards, Joost

Hi Joost
I am more than happy to share any experience with this MB, just keep an eye on this thread for i will update it with all the info i think is relevant.
But one thing you should think about is what Dreamslacker said is that with the 1x Pci-e bandwidth we are limited and that the atom cpu is not too great for shoving alot info… Just mentioning it because you said you are using it for a NAS.

Just to confirm, I have used the Intel PT dual port gigabit server adapter with PCIe x1 (x1 in x4 open back slot) before and it works just fine.

After taking the LCD board of the 2nd board with the 4 buttons on, it shows 16 pins connector.
See pics attached, so here is the question, is there ANY chance that they are using a HD44780 controller and that i can use this schema to connect it?? http://lcdsmartie.sourceforge.net/circuits.htmWill look for and old PC with a parallel port and test.. Have nothing to loose ;D ;D

Nope!
The keypad is just connected across 4 of the input lines on the parallel port.

Nope!
Steve
Damn, so in you best opinion should i just give it up and get a cheap HD44780 LCD??
Would be like a small defeat, but i can take that.. -

Would be like a small defeat, but i can take that..Probably the most cost effective method. A HD44780 LCD can be had for less than US$12 inclusive of shipping on ebay. i'm sure your time spent trying to reverse engineer the Firebox LCD would be worth more than that.
-
I'd be surprised if it isn't a standard parallel port header. Everything else on the board is standard.
Give the firebox LCD a go first, you've got nothing to loose. ;)Steve

Do try mate… It looks like that could be a regular HD44780 LCD module that was previously piggybacked onto another controller (hence the need for a different protocol to communicate with the intermidiary mcu).
-
Re-reading what I wrote it's not clear.
What I meant to say is that the 2nd board is almost purely passive. It serves only to add the keypad to the LCD module and provide a common mounting.
Removing the 2nd board simply leaves you with the same interface but no buttons.Steve
-
Based on the picture of that LCD unit and the brand… I reckon that should be a KS0066U lcd. Do try running it with a parallel port and as a HD44780 LCD. It should work. Pins 15 & 16 will be the backlight pins if that's the case.
Update: Based on the driver used, that's definitely HD44780 capable. Just that the mapping was somewhat different when used with the Watchguard backplane and keypads.

Thanks alot both of you for helping me with this. i will give it a go and if it do not work, at least i will have everything ready for a HD44780 LCD.
So now i am looking for a good wiring drawing to see if i need one or two potentiometers , some say one and some say two…
Dreamslacker do you know if the KS0066U is compatible with the HD44780 wiring? some sites say it is.

Yes, it is. Seems that the LCD is from SDEC anyway so the connection to the parallel port should be similar to connecting a HD44780 LCD. The only caveat is that if they do not use a HD44780 controller, then you need to test with Linux/ pfSense and LCD proc with the sdeclcd.so files.

I agree looking at the hardware it seems it should be HD44780 compatible. However it has a custom part number so it could be a special for Watchguard. Anyway it's an easy enough test to run and I can confirm that it doesn't work, at least not in 8-bit parallel mode with lcdproc 0.55. It's locked up my box now so I'm rebooting to test 4 bit mode.
Steve
Edit: I'm fairly sure it won't work since the backlight is controlled via the strobe bit, pin 1.
