Checkpoint 13500 LCD Screen

stephenw10

If you unplug the screen and boot without it do you lose the cuaU0 and cuaU1 devices?

Kind of hard to see in the picture, how many wires are in the LCM connection?

It looks like it might be two USB devices, I imagine one for the button array and one for the screen.

Try running at the command line usbconfig dump_all_desc that will show you all pfSense knows about those devices.

Had disconnected the display and started up the server. Non of the "Com port(s)" changed. I took a few more pictures of the connector.

Here is the usbconfig dump_all_desc

Here is the pciconf dump

The usbconfig output was taken with the screen connected? That sure looks like USB connections. Hmm.

Those /dev/cuaUx devices are USB connected com ports so it they are not that then you must have something else like a 3G modem or GPS etc. But looking again that's just what is shown in lcdproc, I don't think that list is dynamic. Check to see what actual ports you have available in /dev.

4x 10G NICs and 16x 1G NICs? Nice!

Here you go.
dev.txt

That was my thoughts about that port looking like usb.
The dev/led didn't show anything good. It was just showing locate/fault of the nics.

stephenw10

Ok, so no additional com ports shown.

Was the usb_output.txt file above taken with the screen still connected?
If not then reconnect it and take that again.

It's hard to believe that is not USB.

Heres an updated usb and pci dump.

Com port list

stephenw10

That list on com ports will never change. It's a static menu in the lcdproc package.

That lead is almost certainly USB. The colours are pin positions all point to that.

If you boot the Checkpoint OS does the display work?

Is it possible that should be on the USB header next to it? Or was it glued to the LCM header?

Steve

demonmaestro

Never had the software on it when I got it.
It was glued to that header that it is currently plugged in.

stephenw10

Hmm, hard to imagine how it would not be seen by usbconfig. I'm wondering if it has another usb controller pfSense can't see. Or perhaps it's not USB at all and they just used that cable because it was available....

The any sort of clue at the other end?

demonmaestro

This is the only thing that's on the other end. Not much to go on.

I can load the checkpoint OS on it if I can find it.

Ah, great, that will prove the screen is connected correctly at least. There may also be some clue in the boot log about how it's connecting. There may be something in the BIOS is you have access to it.

@stephenw10
Didn't see anything in the BIOS.
The BIOS had a password on it. I don't know if someone thought they were being funny or what. It was set to {removed}.

I'll load up the original OS and see what can find. Unfortunately I don't have any way to do a screen capture. Any ideas?

stephenw10

I removed the BIOS password as I'm not sure Checkpoint would be happy about it. That's the same password that's been on every CP box I've seen though. It's easy to find on the internet for anyone reading this.

demonmaestro

Okay got you some logs from the checkpoint OS
usb-devices.txt
dmesg.txt
Also the screen works with the proper OS installed.

stephenw10

Hmm, doesn't look like USB then.... nothing shown in the boot log that looks interesting either.

I'd probably try to locate the system that is built from or something else with the same LCD and see if that has a manual detailing it. Most of their stuff is Portwell IIRC and the NIC modules in the 13500 still look like that but I don't see anything like that LCD available.

Hi ....

Also i have the same issue about run the LCD
finally did you found the way to put to work the screen
Kind regards

stephenw10

Not as far as I know. I've never seen any reports of one working.

From the perspective of the host appliance, that IO board is what matters. There is an NXP LPC1343F that seems to be in charge. Datasheet is here: LPC1311/13/42/43.

This is the list of "serial" interfaces available:

USB 2.0 full-speed device controller with on-chip PHY for device (LPC1342/43 only).
UART with fractional baud rate generation, modem, internal FIFO, and RS-485/EIA-485 support.
SSP controller with FIFO and multi-protocol capabilities.
I2C-bus interface supporting full I2C-bus specification and Fast-mode Plus with a data rate of 1 Mbit/s with multiple address recognition and monitor mode

USB has the MSC (mass storage) and HID (keyboard/mouse) profiles.
