Example
This is how to set the PIN number on a new hopper to 1-2-3-4 which does not already have
one…
Command = Enter new PIN number
Transmitted data : [ 1 ] [ 2 ] [ 3 ] [ 4 ]
Received data :
ACK
Subsequent use of this command will still return an ACK but will not actually change the PIN
number to any other value. This is a ‘use once’ command.
As soon as a PIN number is programmed, the ‘Dispense hopper coins’ command will fail
until this PIN number is re-entered with the command below.
Likewise, after powering up SCH2 with the PIN number mechanism enabled, it must be
entered prior to paying out coins.
Command = Enter PIN number
Transmitted data : [ 1 ] [ 2 ] [ 3 ] [ 4 ]
Received data :
ACK
Note that an ACK is always returned, even if the PIN number is incorrect. This increases
security.
