When a reader is configured for SingleVend operation, a signal is sent from the reader to the machine via an electrical or digital pulse. This is the same type of signal the machine would receive from a coin drop. This signal is sent via a one-way communication harness, where the reader does not know anything about the state of the machine. It is simply sending a vend start pulse to the machine and will report that it is in use or idle depending on the assigned cycle time.

Vend
...
Sequence
The customer drops coins or swipes a card (credit or loyalty).
Price decreases on the reader.
Once the vend price on the reader has been met, the reader will pulse the machine.
The price decreases on the machine.
Once the machine has received all of the pulses and the vend price is satisfied, it will be available to start.
Terminology
Pulse Length: The length, in milliseconds, of the signal sent from the reader to the machine. See also: Determining Pulse Length and Interval.
This value varies from machine to machine.
Pulse Interval: The length, in milliseconds, between each pulse.
If set too low (fast) the machine may not recognize all pulses sent from the reader. The higher (slower) the pulse interval is, the longer it will take before the machine is ready to start. See also: Determining Pulse Length and Interval.
Pulse Type: The method in which the reader pulses the machine, e.g. Relay, MLV+, or MLV-.
Unless otherwise instructed, always use Relay.
Sensor Input: Used to detect if the machine door is open or closed.
Only available on certain machines with certain start harnesses.
Show Remaining Time: Controls whether the reader will display the time remaining based on the Cycle Time assigned.
Cycle Time: Because the reader does not know if the machine is running, a separate configurable timer is used for the reader.
On washers, the timer is used to prevent additional vends.
On dryers, the timer is used to determine if an additional vend should be charged as a top-off.
# of Pulses: The number of pulses triggered to start the machine.
This should be set to the machine's internal vend price divided by the coin value. See Determining the number of pulses section below.

The number of pulses depends on the vend price and coin values on the machine. To determine the number of pulses, take the vend price divided by the coin value.
Example calculations | ||
---|---|---|
Mach. vend price | Mach. coin value | Pulses |
$3.75 | $0.25 | 15 |
$2.00 | $2.00 | 1 |
$8.00 | $1.00 | 8 |
$1.00 | $0.50 | 2 |

Configuring machines
FasCard can be configured to start a machine whether it takes one pulse or multiple pulses to start. However, there are pros and cons to both setups.
...
For a machine to start on one pulse, the machine's internal vend price and coin value must be set to the same values. The same rules apply to the FasCard equipment type setup.
Pros
Only 1 pulse is sent so it is less likely for the machine to miss a pulse.
Ideal for locations that are 'Card-only'.
Cons
If the machine currently starts on one pulse, it will require re-configuring the machine. Though once configured, it will not need to be changed again.
Multiple pulse setup
For a machine to start on multiple pulses, the machine's coin value must be a factor of the machine's internal vend price. The same rules apply to the FasCard equipment type setup.
Pros
Only requires configuring FasCard to send the correct number of pulses.
Ideal for equipment that has a lower price point.
Cons
Possible for the machine to occasionally miss a pulse, especially on more expensive machines (eg. $8.00 washer / $0.25 coin value = 32 pulses)
SingleVend modes
The listed modes, below, cover the various features and pricing capabilities each mode can be configured to. Certain modes are limited to specific types of machines and will be noted as such. Use the 'Choosing a SingleVend mode' table at the bottom of the list to reference the type of mode you need for the equipment you are working on.

Simple mode is used when equipment is configured with a single price to start. Example setup |

Top-Off mode is used on dryers when a separate price is charged for additional top-off vends. While idle, the reader will charge the Machine Start price. While running (determined by the Cycle Time setting) the Top-Off price will be charged. Example setup In the above example, the equipment is configured for a $0.50 start price (2 pulses) with an 8-minute cycle time. Additional top-off vends are $0.25 (1 pulse) with a 5-minute cycle time. |

Similar to the Top-Off mode, the Extra Option mode allows a limit to be set regarding the number of times the added option can be purchased. Additionally, the ability to purchase the extra option can be set to expire. For example, if you are setting up a washer in SingleVend mode that includes one modifier, then the extra available option would be assigned to this modifier with a limit of one time.

Choosing a SingleVend mode
There are five (5) SingleVend modes, each serving a different purpose. The mode to use depends on the type of equipment and how the machine will be priced. The table below lists the SingleVend modes used for specific types of machines and their reader quantities.
Reader qty | Equipment type | Pricing | SingleVend mode |
---|---|---|---|
1 reader | Washer | Single price | Simple |
1 reader | Washer w/ one modifier | Single start price + single modifier | Extra Option |
1 reader | Single dryer | Single price | Simple |
Top-off pricing | Top-Off | ||
2 readers | Stack dryer | Single price | Simple |
Top-Off |
pricing | Top-Off | ||
1 reader | Stack Dryer (single control board) or | Single-price | Simple |
Variable pricing | Multi-Option |
Warningnote | ||
---|---|---|
title | Advanced | modeMode It is not recommended using Advanced SingleVend mode as it may cause issues in how the way the reader presents start and top-off options for the machine. This mode should only be used as a last resort if the operator is looking for niche settings to be programmed into the reader. |
Tip |

Stack Add-on Board In a situation where a stack dryer is using one reader for two separate controls, a Stack Add-on Board will be required. Both machines should be paired together on the Admin site, presenting selection arrows on the reader to determine where the start signal will be sent to (top or bottom pocket). When using a Stack Add-on Board any available SingleVend mode can be used. |
