Coke Machines
- PREFACE
-
- Coke vending machines
are everywhere. They're getting more and more
like regular computers with LEDs that show
little "ICE COLD" messages and whatnot. Well,
there's a lot more to those little built-in
computers than you may think. Included in the
low-level operating system that these babies
run on is an actual debug menu that gives you
access to all sorts of machine information
and possibly gives you free cokes in older
machines. Scroll down for a new exciting
product only offered here.
-
-
-
- WHICH MACHINES
WORK?
-
- There's a very strict
list of vending machines that have the debug
menu. First off, they're all COCA-COLA
product vending machines. This means the
giant, un-missable picture on the front must
show any of the following: Coke, Dasani
(Water), Barq's Root Beer, Vanilla Coke,
Cherry Coke, Sprite, Evlan (water), Fanta,
Fresca, Frutopia, Hi-C, Sprite Remix, Mad
River, Mello Yello, Minute Maid, Nestea,
Odwalla, Mr. Pibb/Pibb Xtra, Planet Java,
Power Ade, Seagram's Ginger Ale, Simply
Orange, Sparkletts, or Tab. Of course
anything Diet or Caffeine free works too.
- The machine must have
an LED screen. Some of the older ones just
allow the LED to be set to a price amount and
won't have the debug menu. You're safer if
the little LED is telling you something.
Usually it will scroll a little message like
"Ice Cold Cokes". Newer machines are more
likely candidates.
-
-
-
- ACCESSING THE
MENU
-
- To enter the menu,
there's a button combination.
-
- HERE'S THE
ONLY THING YOU HAVE TO REALLY REMEMBER:
-
- [4]-[2]-[3]-[1]
-
- The buttons are
numbered depending on how they are
positioned. They will either be vertical
(more likely), or in horizontal rows of 4
buttons per row. If it is vertical, the first
button is #1, the one below it is #2, and so
forth. If the buttons are in horizontal rows,
the first button is #1, and the one to the
right of it is #2. The numbers work like a
type writer after that. In rows of 4, the
first button of row 2 will be button #5. So,
to review, getting in to the debug menu looks
like this:
-
- COKE MACHINE::::::
- $1.00 -------
- -------------
- [ Coke ]
<-- Hit this button last
- [ Coke ]
<-- Hit this button second
- [ Diet Coke ]
<-- Hit this button third
- [ Sprite ]
<-- Hit this button first
- [ And so on ]
- -------------
-
- Some text should show
up on the LED (probably the word "Error",
we'll explain what it means next sections).
If nothing happens, your machine doesn't have
the debug menu.
-
- NAVIGATION
-
- To navigate from
option to option (What they are is next
section), remember the numberings we gave the
buttons. They work as follows:
-
- Button [ 1 ] -
Exit/Back
- Button [ 2 ] -
Up
- Button [ 3 ] -
Down
- Button [ 4 ] -
Select
-
-
-
- OPTIONS
-
- Depending on the age
of the machine, you will get a varying amount
of default options available.
- On older machines:
SALE, VER, EROR, and RTN
- On newer machines:
CASH, SALE, EROR, and RTN
-
- CASH - Machine
Earnings Display
-
- The CASH option will
display how much money is in the machine
currently. It generally takes a second or two
to load. From here, you can scroll up and
down through 12 or 16 different options,
depending on the machine age. These other
options display how much money was spent on
each individual item, classified through its
button (or slot, as I like to call it)
number.
- A neat side note about
the slot numbers is that there are more slot
numbers than there are actual slot, so
usually the last 4 buttons contain zero
money. This could be so that the same OS
could be used on bigger machines, but the
newer machines have even more slot numbers.
-
- SALE - Total Sale
Count
-
- The SALE option
displays how many drinks have been sold out
of the machine. This tends to be cumulative,
but not on all machines. The stock guy is
probably supposed to reset this each time he
re-stocks. Also, this has the same
sub-options as the CASH option, where you can
scroll up and down and see how many drinks
have been sold from each slot.
-
- VER - System/Machine
Version?
-
- This option will cause
a large alphanumeric string to scroll across
the LCD. The number looks very much like a
serial number, but doesn't vary from machine
to machine. It is most likely the OS or
machine version number, but of the older
machines that have the option, I haven't seen
one that doesn't have the same number.
-
- EROR - Error
Log
-
- There are 8 different
types of errors - COLJ (Column Jams), VEnd
(Vend Mechanism), door (Door Switch), sels
(Select Switch), CHAR (Changer Errors), acce
(Acceptor Errors), StS (Space-to-sales
errors), and bVal (Bill Validators). The
separate types and actual errors are useless,
as you assumably can't get inside the
machine, BUT(!) you can clear the errors.
Hold the enter (Number 4) button down for
about 2 seconds, and it should clear the
error.
-
- RTN -
Return
-
- This is simply the
return option. Selecting this will exit the
debug menu. On newer machines, pressing the
BACK button at the main menu will not exit,
and RTN must be selected.
- A side note: The menu
can also be exited by pressing the coin
return button.
-
- EXTRAS
-
- By holding in the coin
return button and not releasing, on the newer
"big-button" machines, this will display the
internal temperature in Fahrenheit, as in
"42F".
-
- **Update**
-
- There are many more
menu options that are only accessible if
they've either been enabled from the computer
inside the machine, or on the internal
computer behind the door (Probably not
feasible for you to access).
-
- CPO - Coin Payout Mode
-
- You can can dump coins
from the coin mechanism, and the various menu
options allow you to choose which type of
coins (Nickels, dimes, etc.) are dumped.
-
- tVFL - Tube Fill
Mode
-
- This is useless to
you. This allows you to load coins into the
coin tubes, which you can't do from the
outside.
-
- TEST - Test
Routines
-
- This allows you to
test the following various
routines:
- SE Allows you to test
the buttons. Will give you number
- of button when you
press it
- SP Sold-out paddle
test. Not quite sure, most likely internal
function.
- Su Sold-out switch
test. Same as paddle.
- CO Motor test. Will
run various column motors.
- Cn Coin test. Put in a
coin and it will tell you what kind
of
- coin it
is.
- nA Note acceptor test.
Same as Cn, but for bills.
- dSP Display test. Will
illuminate various LEDs.
- vErS Rattles off
version number.
-
- RELY - Relay
test
-
- This tests the relay
electronic control of various parts. Do not
do, as it will cause damage if various
internal parts are not unplugged before
usage.
-
- PASS - Password
-
- This is not normally
accessible, but allows you to change the menu
password from the 4-2-3-1. Whoo!
-
- PrIC - Price
Setting
-
- Used to set the price
for a drink. Not sure how to work it, but it
seems simple enough.
-
- StOS - Space-to-sales
routine
-
- Lets you change the
STS routine and other options. This means
that various buttons will all mean the same
thing, i.e. the 6 coke buttons don't actually
vend from 6 different columns, but vend from
one (changing when one runs out of
course).
-
- COn - Machine
Configuration/Permissions
-
- This is the machine
config menu that decides what of these
options you are allowed to access through the
outside panel. This is probably only
accessible with the door open. I won't go
into detail, but I'll list the Config numbers
and what each do: C1 sets price menu on, C2
sets special (manufacturer) options on), C3
disables the "ICE COLD COKE" message. C4 is
autoviewing of menu when door is opened, C5
is door switch status, C6 is mysteriously
reserved for "future use", C7 determines
whether your money credit stays in for 5
minutes or indefinitely, C8 is Force Vend, C9
allows multiple vends without putting in more
money (i.e put in a 5 and get 3 cokes and
then your change), and C10 is Escrow Inhibit.
-
- CCoC - Correct Change
Only Control
-
- Adjusts Correct Change
only rule to your liking.
-
- TIME - Time
Adjustment
-
- Allows you to set the
machine's local time.
-
- LANG - Language
Selection
-
- Not sure how many
languages are supported, but there are
apparently more than just
English.

-
- Unless you can get
behind the door, there's little you can do
with this except impress your friends.
However, if you're able to set the C-switches
properly, you'll be able to manipulate the
machine in any way you want, get free drinks,
change the price, set up cool
buy-one-get-one-free deals, etc, etc :). Not
to forget, knowledge is power. One step
closer to free sodas!
