Vender Programming
PRECAUTIONS TO TAKE WHEN
WORKING WITH CONTROL BOARD
As with any printed circuit board, our electronics are
very sensitive to Electrostatic Discharge (ESD). Simply
walking across a tile or carpeted floor can generate a range
of 30,000 to 50,000 volts of electricity. One ESD can be
enough to seriously damage your control board or at least
weaken it enough that erratic problems could occur in the
future. Even a discharge surge under 100 to 200 volts
is enough to create problems within the circuitry of the
electronics. It is advised when storing the electronics that
they be kept in anti-static bags, even if the electronics are
thought to be defective. If a control board is thought to
be defective and is really not, it soon will be after being
charged with ESD. The ideal prevention against ESD is
to use anti-static conductive wrist straps which ground
you to the machine before touching the electronic boards.
If it is not possible to use these, at least ground yourself
before handling the electronic boards by touching the
metal framework of the vender. Whatever method you
use, always handle the electronic boards by the edges. Be
careful not to touch the components on the control board.
TOUCH PAD PROGRAMMING
It is very important that the RVV Gen II is programmed
properly. All programming of the vender options is done
in the Service Mode. To enter the Service Mode, open the
vender door, and press and release the blue mode button
located on the control board.
The vender’s touch pad consists of 12 buttons. Five of
these buttons (see Figure 3.1, below left) are used to
program the vender and navigate through the service
routines, plus two are used to move the elevator cup (in
“Product Location”), as follows:

The controller will automatically return to the Sales Mode
if:
• No response from the touch pad is received for
approximately five minutes;
• The service mode button is pressed a second time;
• The “Return” mode is activated (with door open); or
• The door is actually closed.
If credit exists, the credit amount will be displayed after
returning to the Sales Mode.
MENU SYSTEM
When programming, you must first use the programming
buttons listed above to maneuver through menus and sub-
menus before you will be allowed to accomplish your task.
Each menu consists of various items, or modes, such as
“Set Prices” Mode or the “Set Time / Date” Mode. There
are two menus:
1. INTERNAL (Service) MENU - This menu is available
only with the vender’s door open. It is accessed upon
pressing the control board’s mode button.
2. EXTERNAL MENU - This menu is available by
entering the proper external password with the
vender’s door closed.
(See “Preview Password” in the
following section.)
From this menu, cash / sales counts
and vender errors can be read (but not cleared).
