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.

@Pepito-Payet said in Operate checkpoint 4800 LCD screen with pfSense (EZIO-G500):
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.

you store or your images that you post? I can't seem to get them to post on the forum like you.

@saint-frater late to the party but hope I can help anyways. My g500 acts very strange. For instance the “move cursor to leftmost position” is 0x28, the “clear screen command” is 0x38 or the enter button returns a 0x75... odd
The setup I’m using is quite simple: the G500 is attached to a 5v power supply and to read/ write I’m using an arduino nano -
@spolverino long time I've played with that.
I'm quiet sure that the issue you face is due to the voltage of your arduino's serial Interface.
If I remember well, I've the same issues with my arduino, until I use a small USB Serial interface on my PC.
you may see it behind the breadboard, (the DB9 connector):
I think, on the Arduino, the serial interface is 3.3V max, and the G500 is running at 5V... when voltage is not correct, you get strange behavior from the G500, and you may get in trouble with your arduino...
