LK1800M POS programmable Keyboard
« on: Fri, 25 March 2011, 19:29:13 »
I was told I should come here for what I seek.
I just got this keyboard from a used computer parts store about an hour ago. There aren't any ports or wires on it other than an Ethernet port. I'm assuming it was from a cash register or something because it has 30 extra programmable keys on it.

The model is a LK1800M.
Trying to get it to power on through an Ethernet cord on my laptop but I obviously need a driver or something. Also, it has a key slot and a Credit card swiper. ****ing awesome.

Is there any way I can get this to work on any computer? The only port on it is an Ethernet port and I want to be able to do what I want with it. Coolest god damn keyboard ever. And it was only $3.
Sorry for the horrible quality images, my phone sucks.

Welcome to Geekhack!

Take pics.  Especially that ethernet part - are you sure it's not RJ11?

Oops. Thought I already attached the pics. Lemme try that again.

Hmmm...... keep looking. That may be a barcode scanner port.  

And unplug that Ethernet cable.

Side story:   I once plugged a USB plug into a RJ45 and it wasn't pretty.


I'm pretty sure it's supposed to be some kind of twisted RJ45 port that leads to a terminal. The bar code scanner would be plugged into the terminal I would assume. The Keyboard isn't plugged in currently.

And how did you get that to fit? Did you splice the cord and attach it to the pins?

You take your USB cable and shove it into the back of your computer while under a dark desk.

Wait - don't do that, I was talking parenthetically!

Yeah, having dual Ethernet ports is quite nifty. What would be more nifty is if I could get this keyboard to work with it.

Well ****. You think there is a cord that I could buy/make that would convert the signals from a PS/2 or USB to RJ45? I've found the manuals and program needed for the keyboard, all I need is for my computer to see it's there.

Well, what does the manual say?  It MAY be a RJ11 to PS/2 special cable.


I'll keep looking and get back to you on that.

It's an RJ-11 to PS/2 interface.

Are you sure? I count 8 pins on my keyboard.

Well then, are you sure it's an LK1800M and not LK1800MU?  The MU would have a USB interface and have this pinout:

Yes I am sure it's a LK1800M and there is only one port on the back, that's the 8pin socket. There are no cords or wires, just what looks like an RJ-45 port.

I got the keyboard to power using that pinout you provided.

Only thing is I'm not able to turn on caps lock or send any inputs, and the program I found off of the website doesn't find the keyboard. And device manager doesn't see it either.

I think it might be the key. Would anyone know how to unlock it?

Wooo! I got it to work and its ****ing Boss. The card reader works perfectly and types out what ever it reads. The key however was a problem, I had to open the keyboard and put a wire that connects the positive and negative together so it's never locked and the current is always going.

Here's what I did in case anyone is interested.


Keyboard works fine though, thanks to all for the help.

That looks like the standard "Hey you, no fooling around!" type lock. They can be found on older computer cases, electrical panels and things that people shouldn't be fooling around with, but no one actually wants to spend money locking up. The keys are all interchangeable. In fact, you can probably just turn that with an unbent paperclip or a small screwdriver. See how the smaller inner circle has a notch on it that is lined up with the upper notch on the outer circle? Stick something pointy in that inner circle's notch and turn it clockwise so it's lined up with the lower notch on the outer circle. Unlocked! :lol: Proper keys can probably be found at the computer store you got the thing from.
