Card Reader Installation
"Coin 1" and "Coin 2" Inputs
The card reader can be connected to either "coin 1" or
"coin 2" inputs. Connection to the "coin 2" input is
recommended to simplify operation. The "coin 1" and
"coin 2" inputs can be accessed via the orange 16-pin
connector plug which connects to the V-computer
board connector labeled "J1". Refer to Figure 4.

Using the "Coin 1" Input Connection
The card reader must simulate a coin drop meter
signal, thus providing a signal from a contact
closure or isolated open collector that goes low
(logic "0", below 0.4 Volt DC and above ground
0.0 Volt DC) for more than 15 milliseconds but
less than 130 milliseconds. When not low, the
signal must be at a valid logic high (3.3 Volts DC
minimum, up to 5.0 Volts DC maximum). If the card
reader provides normally open contacts or a normally
OFF open collector interface to the "coin 1" input,
the card reader will work as long as the timing is
as explained above. Each pulse lasting 15 to
130 milliseconds is then counted as though a coin
had been added. By programming the vend amount
and the "coin 1" denomination at the same value,
only one pulse is needed from the card reader.
By using this input connection, a U.S. quarter or other
single denomination drop coin meter may also be
connected to the "coin 1" input.
Using the "Coin 2" Input Connection
The card reader can connect to the "coin 2" input if
the timing restrictions given above are not satisfied.
The voltage levels listed above still apply for valid
low and valid high. The card reader MUST provide
a logic high level (open contacts) at start-up to avoid
inadvertent starting. When using "coin 2" input, a
low level signal for any duration longer than
20 milliseconds will start the cycle. It does not
matter if the card reader provides one pulse or a
series of pulses, the vend amount will be satisfied.
Programming the vend amount and the "coin 2"
denomination at the same value is recommended.
