2.3.16 - Test 18 Coin Mech Encryption Code
In order to improve note acceptor security the machine software requires an encryption key
code to be set. This is necessary following replacement of either the MPU6 Unit or the
acceptor.
To facilitate installation of an encrypted SR5E coin mech for the first time enter test 18 to
enable an encrypted code to be entered for the Encrypted coin mech. This number is printed
on the coin mech body.
Power up the machine and enter the test routine using the second test button, which should
be selected simultaneously with the program modules test button. RH1 is used to increment
from test 1 to 18 then the RH2 button must be selected.
On entering test 18, one of the following text messages is displayed on the Alpha Display.
Key = 0 0 0 0 0 0 or “KEY KNOWN”
The first digit is automatically selected and will be flashing. The LH4 and RH4 buttons
increment and decrement the first number of the encryption code.
Selection of the LH2 and LH3 buttons causes the selected digit to move from left or right
respectively.
Once the code has been entered the RH3 button should be selected to accept the code and
one of the following messages will be displayed
If the key code has already been set up and is valid then the display indicates “KEY
KNOWN”.
If the key code is incorrect then the display indicates “COIN MECH NO RESPONSE”.
(Refer to section 2.11 for button definitions).
