Operate checkpoint 4800 LCD screen with pfSense (EZIO-G500)
-
If you find any details of the protocol the screen uses let us know. It may not be that hard to develop a driver once that information is available.

do you know where i can find this?
-
Nope, I never found it. You could try to contact Portwell and ask.

I believe the only hints about these better EZIO devices came in a PDF document titled "NAR-7100 Series Communication Appliance" by Caswell/Portwell (Google it). It refers to the EZIO-400 but wiring pictures in that document seem awfully similar to your picture above.
There is a list of commands to send, and they do not match the EZIO-100 or EZIO-300 we already have, so maybe they do work for an EZIO-400.
As you have the hardware, you might have to try them at the command line. The device might be attached to COM1 as the documentation suggest, or COM2 (COM1 is usually the serial console).
So, install an operating system you are comfortable with, initialize the COM port (looks like 115200,n,8,1 would be a good start) and hack away. Start by sending a few characters ("Hello"), next try clearing the screen, then put the cursor somewhere and sending another "Hello".
Let us know what you find out.

Ah, I see it. Yeah the G400 is also a graphical display, though lower resolution.
The G500 has a bunch more buttons are lights etc. All the bells and whistles.
If you just write raw serial to it (from lcdproc here):
Experiment time!

Hello,
I have pfsense installed on it but I don't know how to run the commands to get it displayed on the screen. How to do it please?
-
Looks promising.
[root@T-160 /bin]# echo -e '\x0c\x0bSome test text\x0a\x0dAnd a new line\x0a\x0dAnd another' > /dev/cuau1Results in:
Seems like there might be a generic driver that would cover this....
-
So you found it?
-
A driver? Nope. I just send commands to the LCD directly to test if the G400 command list works and it appears it does. I haven't tested them all. The backlight command does nothing.

Watching as I too have several of these Checkpoint devices and would love to get the display working.

I would love to be able to get the LCD working on a Checkpoint 4600. I have no programming skills to donate to the cause, unfortunately. but would love to help someway

Hello peoples,
I've tapped a Checkpoint 4400's EZIO serial communication; and that some commands are way different from the G400.
I'm still making some data decoding from the tap file, but I've so far, I've discovered that Checkpoint isn't working in text mode, they transfer all menu via graphics...
I don't know how to share my findings ?
-
If can't post here directly you can link to a share somewhere, pastebin etc.
We don't need a graphics mode to use the G500 with lcdproc though.

I've started to build some git site with all information I can collect from the tap, but also from the CP's process...
here is the binary tap file:
https://git.nox-rhea.org/globals/reverse-engineering/ezio-g500/-/raw/master/TapFiles/Tap_1.hex?inline=false
I'm still reading the file and the application to try to find as many information I can find...

Hello everyone,
Since I've an working 4400 with demo license on it, I'm able to tap all serial communication...
I've started some RE on the CP's drivers... very interesting...
I've discovered that CP is indeed full graphics...
The LCD graphic mode is very special but logical, each bytes represent 8 pixels 'vertically'...I've also be able to control the 3 LEDs:
https://git.nox-rhea.org/globals/reverse-engineering/ezio-g500/-/blob/master/LED.MDhere is the current command discovered so far:
https://git.nox-rhea.org/globals/reverse-engineering/ezio-g500/-/blob/master/CommandSet.MD -
Ooo this is nice work.
Definitely some differences to the G400 command set then. Mostly the same though.

perate the checkpoint 4800 screens on pfsen
Did you able to get VGA out to instal pfsense in checkpoint 4800
if you know how to connect the cable to VGA adapter let me know -
Hello,
I used a USB cable to turn it into a VGA cable to plug into VGA inside the checkpoint. But the console cable also works.
