Standard mode

In standard mode, the vending device offers only two price selections. Each selection transmits its
own vend pulse, which is registered in the Datatron III by an opto dedicated to that pulse. Two
corresponding relays enable the vending device at the appropriate price level.
For this scenario, let's assume the vending device is a copier and that the price-2 selection costs
more than the price-1 selection.
1. The customer enters his PIN number on the Datatron III keypad.
2. The value in the PIN account is compared with both price-1 and price-2.
• If the value in the account is greater than or equal to price-1, relay 1 is enabled.
• If the value in the account is greater than or equal to price-2, both relay 1 and relay 2 are
enabled.
3. The customer makes a selection and presses the copy button.
4. The incoming vend pulse is detected by the corresponding opto. If the appropriate relay for
that price level was enabled (i.e., there was enough remaining value in the account), the
account is credited and the copy is made.
• If a price-1 debit pulse was detected by opto 1, the unit credits price 1.
• If a price-2 debit pulse was detected by opto 2, the unit credits price 2.
The customer continues making copies. When the remaining value in the account falls

below a price level, the corresponding relay is disabled, and subsequent vend pulses for that
selection are ignored. The relays are also disabled if the user presses D on the keypad,
ending the transaction.
