(h) Cup Test
Causes a cup to be dispensed by the cup drop mechanism. The cup carousel will not
index, unless a selection is made, or a cup test performed. This reduces the possibility of
damage; prevents damage to the carousel occurring because the cup stack has been
pushed up from below causing a false out of cups signal to the control board.
Section 3
Programming- Internal
1. The Neo vending machine has a configuration program to allow the behaviour and function
of the machine to be changed to meet a customer’s requirement. While many of the
functions are accessed via the Touch Screen, for ease of use while accessing the machine
internals several functions are available via the internal keypad. Access is protected by
means of a four-digit code. The facilities available are shown below:
(1) Engineer level access
• Full access to all features
• Factory default code 4444
ACCESSING THE USER PROGRAMS
2. The programs are accessed by pressing key 5 (PROG) on the INTERNAL keypad.
The EXTERNAL display will then prompt for input of a four-digit entry code. The code is
input using the numbers printed on the keys of the INTERNAL keypad.
(2) After pressing the PROG key, the display will change to: -
PLEASE ENTER
ACCESS CODE
(3) Use the numbered keys on the INTERNAL keypad to enter the correct code. It is not
necessary to press ENTER. The code will be checked on entry of the fourth digit.
Three attempts are allowed before the PROG key must be pressed again. On entry of
a valid code the display will change to the menu heading appropriate to the level of
access.
(4) In the event that the code has been lost or when fitting an un-programmed
replacement board, it is necessary to complete the circuit between the two pins of the
two-pin header labelled ENG LINK on the Control Board. These bypasses the entry of
the four-digit code, giving the engineer level access to the bootloader and the
engineers mode. If the ENG LINK is left in place during power up, the machine
will start straight into the engineer’s program asking whether you want to use
the bootloader or bypass straight into the engineer’s mode.
NOTE REGARDING POWER UP PROBLEMS
3. The Neo electronics control system has two major elements. These are the Control Board
and the DC RIO board. The two boards communicate via a three wire Inter Integrated
Circuit bus (I
2
C bus). Some faults affecting the I
2
C bus or Control Board configuration can
result in persistent system resets. To allow recovery / diagnosis from such situations, the
control system provides an Access Window to a special ‘safe mode’ shortly after power is
switched on. It is possible to enter the engineer’s mode during this window.
