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:
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.
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.
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".
