Steering mode
The Datatron III monitors two different pulses from the vending device. One of the signals carries
information about the selection made by the patron. The other signal is the vend pulse for any
price.
Sequence of events
1. When the patron enters a PIN code, an opto (opto 2) in the Datatron III registers the size &
color selection in the vending device to determine the vend price.
2. If the remaining value in the PIN account is enough to cover the price level selected, then
the relay enables the vending device.
3.
When a vend is made, a pulse is sent from the vending device to the Datatron III. This pulse
is registered by opto 1, and the appropriate price is logged to the customer’s PIN account.
When the remaining value falls below the selected price level or the patron ends the vend
operation by pressing D, the relay is disabled until a lower price level is selected.

How steering optos determine price
Think of an opto as a switch that is either ON or OFF, depending on the information it receives
from the copier signal it monitors. The selections made by the user are registered by two optos in
the Datatron III. The table below shows that, by using every unique ON/OFF combination of
optos 1 and 2, two price levels are possible.
