Header 236: Read opto states
Transmitted data :
<none>
Received data :
[ payout opto ]
[ payout opto ]
Bit mask :
B0 - payout opto A ( 0 = path clear, 1 = path blocked )
B1 - payout opto B
B2 - payout opto C
B3 to B6 - not used, 0 returned
B7 - payout opto A + B + C
The payout opto whose status is returned on bit 7 is actually comprised of 3 separate opto
paths - A, B and C. If a coin is seen at any of these optos then bit 7 is set.
The optos are continuously sampled in the background and the current state is reported by
this command.
Note that this command is designed for test purposes only ( checking coin visibility on the
opto-electronics ) and not for counting coins during a payout sequence ! Counting coins
during payout is handled automatically by the software and is performed a lot faster than
polling serially.
Header 219: Enter new PIN number
Transmitted data :
[ PIN1 ] [ PIN2 ] [ PIN3 ] [ PIN4 ]
Received data :
ACK
A factory-fresh hopper has the PIN number mechanism disabled.
A manufacturer can subsequently program the PIN number to any chosen value using this
command and after that the number cannot be changed, even if the existing PIN number has
been entered correctly. It is a ‘once-only’ lockout mechanism - turning the power off and on
does not clear the PIN number.
A PIN number of [ 0 ] [ 0 ] [ 0 ] [ 0 ] is legal and would have to be entered.
The ‘Dispense hopper coins’ command is the only one which is ‘blocked’ by the PIN number
mechanism - all other commands operate as normal.
Entering a new PIN number after one has already been programmed will still result in the
return of an ACK even though the PIN number remains unchanged.
The ‘Test hopper’ command can be used to see if a PIN number has been programmed -
refer to bit 7 of ‘hopper status register 2’.
