Can't get keywiz Eco to work

[teeuwen]

Sorry I don't know if this is in the right forum, but I finally got around to soldering my keywiz Eco last night and it won't register any keypress on the entire panel.

I have tried it on two pc's.

The only thing I can think is maybe the ground isn't in the right location? But I have soldered the ground to the ground location on the board.

Any help would be much appreciated.

Just in case you're too young to know.... 

PS2 ports aren't plug and play.  They must be plugged in before turning the computer on.
So first off, do you have it plugged in before turning the computer on?
(from all the way off, not just waking)

Okay, so the only way it seems to fully reset and work is if I unplug the computer and plug it back in and then plug the keywiz in and then turn the computer on.

I think I am getting some grounding issues or something on the player 1 side, but it is registering key presses now so that is good. The joystick seems to be all scrambled on the player 1 side.

If one has never had a PS/2 keyboard attached, Windows most likely hasn't loaded the driver to be able to use it.  Not so different from having never used a USB keyboard, where Windows will load the driver for it, when first connected.  The difference is that Windows isn't notified when a PS/2 keyboard is first connected while the system is already up and running.

Once the system has the driver in place, hot-plugging PS/2 usually works just fine (may be a BIOS issue, if it doesn't).  The only time hot-plugging is of any concern is with very ancient systems.  The old systems with the larger keyboard ports didn't like a keyboard being plugged in while on, and the keyboards of those days were so power hungry that the surge sometimes damaged the MB when this happened.  But those have probably all been land-filled by this point, and anything made in the last 10-15 years is just fine with hot-plugging.

As for the joystick seeming "scrambled", make sure that the inputs are wired to the correct switches on the stick.  From the photos, it looks like you have the red and orange wires swapped on both sticks.

Is there any reason windows won't load the driver? Still having major issues with it being recognized.

The arcade PC I have tried turning it completely off and then plugging it back in with and without the keywiz being plugged in, if not plugged in I have plugged it in and then turned the PC on and still nothing.

I have tried just keeping it plugged in and doing a full shut down and then turning it on again.

Have tried it on my main computer as well and I just can't get anything to load.

Any help would be greatly appreciated.

Should I buy a ps/2 to use adapter?

Okay so I thought about this and I went back and unplugged my usb keyboard and mouse, turned the PC on and then once windows loaded i then plugged in the usb keyboard and mouse afterward.

Simple solution, I had a hard time believing it was something wrong with the keywiz these things are bullet proof.

Alright,

So i know this thread might be a bit annoying with its it works/doesnt work, me coming back before anyone posts....

I am having many issues still.

Now when the keywiz is working, all the buttons are registering fine. all key presses work. my issue is getting the keywiz to work.

I have had times where i havent changed a single thing, and turned my pc on and the computer will recognize the keywiz, (i have two led buttons on the panel)

I have had times where i have booted the computer keywiz lights up, windows is loading and then the computer shuts off mid way threw the boot, and an on reset no lights to the keywiz

i have tried using a ps/2 to usb adapter and i have no success at all with this route, it simply does not recognize the keywiz for what it is.

I have had times where windows will boot with the keywiz and it will be lit, registering key presses and then midway threw it will stop (aka lights turn off on panel and key presses do not register.)

I have built 5 arcades and i am by no means an expert.... but i am not really sure what to do. I am building this Arcade for a friend and would hate to give him something with issues.

Could it be a bad keywiz perhaps? did i do something myself? i have tryed resoldering the ground multiple times, and re-doing any crimp ends to see if it is a possible issue with something i have done, but i am lost.

The computer i am using it on runs perfectly fine when keywiz is not plugged in/or lit up ive stress tested everything.

any help would be greatly appreciated.... perhaps i need to buy a new encoder

As this is an Eco, user soldering comes to mind as the first suspect.  In the photo, I see some solder in the USB connector holes on the board, which should not be there.  Was anything attempted to be connected there?  It should not be.  Make sure there are no misplaced solder blobs shorting adjacent connections in that area on the PCB. 

You say that you have had times when the computer shuts off halfway through a boot?  This sounds like a shorted connection, bad power supply, or possibly some other issue with the system itself, such as a bad RAM module, etc....  If the system is having issues, it's not surprising that a device attached to it is unable to function properly.

Also, I'm also not sure what you mean by "lights up" and "no lights to the Keywiz".  There are no leds on the Keywiz.

The first thing I would do is check for errant solder shorts, and afterward, try a different, known working system.  If you are still having issues, you are welcome to send the interface to me for evaluation.  But we test each unit for full functionality before they are shipped, so the unit should be fine.  Contact me via support email if you need further assistance.

Okay, so I tried plugging it into my main PC using a ps2 to USB adapter, immediately a message came up that said the usb port has exceed the amount of power that is allowed to the port.

The usb area you were talking randy, is that the 4 little holes with the lead away from the central Eco chip, because I think what your seeing in the one picture is the foot of the pcb standoff, I never tried soldering there.

By lighting up in my other post, I meant I have two led lights on my arcade panel that I am running from the 5v on the Eco board.

When I said my PC shut down during boot it was specifically only when the Eco was plugged in. The PC for my friends arcade is brand new and the problem is persisting across two known good pc's.

I have a hard time articulating my thoughts into written word, my mind is usually going a 1000 miles an hour on a couple different non related things at all times.



Can anyone see anything wrong in the pictures I just attached?

Sending this back to the states is not really an opinion I want to peruse the dollar really sucks and it will probably take forever.

Any suggestions from anyone would be great.

Could my gauge of wire be to thick? Could the connectors I be using doing something strange?

Should I cut my losses? Should I re-do everything and possibly make things worse?

Use isopropyl alcohol and a cotton swab/old toothbrush/acid swabbing brush to clean off all the flux on both sides of the board and also what looks like some solder splatter (might just be a reflection/shine caused by flux ) near the middle of the back of the board.

P.S. Another thing to consider is that your mounting screws might be causing a short.

You can make insulating plastic washers by drilling a hole in a piece of plastic and using a hole-punch.



Put the washer between the screw head and the board.

The first question is why your computer indicated that it was pulling too much current through the USB, when you attempted to use a USB to PS/2 adapter?  In most systems, the available power for the USB and PS/2 ports is shared.  The only way the system knows how much power is being drawn from the ports, is through communication with the USB devices, which call out the amount of current they will be using.  If the amount of available current is exceeded, you can see messages like the one you received, or the system may shut down the power to protect the circuitry.  There is no such communication from PS/2 devices, so it really sounds like there are a number of USB devices (or one very "hungry" one) saturating the available current from the ports.  Then, when you try to pull additional current with the PS/2 device, which does not notify the system of it's requirements, it sends it over the limit.  The additional LED's would exacerbate this issue.

Also, the fact that it worked just fine after unplugging the mouse and keyboard (which means those devices are no longer drawing power from the USB port) seems to back up the conclusion of pulling of too much current from the ports as being the culprit.  If the system is a mini desktop or laptop, the power it can supply through the USB and PS/2 ports may also be more limited than with a full-size PC. 

The first thing I would do at this point, is to remove all unnecessary USB devices from the system, and cleanly disconnect the wire from the 5v terminal on the KeyWiz PCB, to eliminate the possibility that there is a short or other unexpected current draw in that wiring.   Then test the unit while it is unmounted.  As I indicated before, all of the units are fully tested before shipping, so the issue seems to be installation / system related.

Randy, just send him a new one.  From the looks of that thing, they're costing you a nickle to manufacture.

Just the MCU on these units costs over 90 nickels, and international shipping another ~300.  And if the issue is what it appears to be, a new one isn't the answer.  I'm actually trying to help him.

Does it work without the LEDs connected?

Are you using the proper resistor for the LEDs for 5v?

Are you sure those are LEDs and not incandescent?
