ALWAYS POWER DOWN MACHINES THROUGHOUT DEVICE INSTALLATION.
Please reference the general Penny and Pulse Installation guides found below:
All generations of Dexter machines prior to "C-Series" operate in a coin pulse only mode. This means that the Cents device will connect only to power, to the coin drop, and to the coin interface on the machine. As such, Cents devices will not report machine state, as this will not be known. Additionally, these machines can only operate in single vend mode.
See the table below for the various generations and machine types with linked schematics for each. Note that each machine type has a slight variation with its coin interface.
Era | Machine Type | Power | Coin Interface |
A-Series & V-Series | 120V to 24V Adapter | 4-pin | |
A-Series | 120V to 24V Adapter | 4-pin | |
A-Series | 120V to 24V Adapter | 11-pin adapter | |
N-Series | 120V to 24V Adapter | 9-pin adapter | |
N-Series | 120V to 24V Adapter | 4-pin | |
N-Series | 120V to 24V Adapter | 11-pin adapter |
Legacy Dexter machines of the following generations require a coin adapter harness:
N-Series (washer and single dryer)
A-Series (single dryer only)
See the guide above for the correct adapter type for each machine variant. Highlighted rows represent machine types that require adapters. Non-highlighted rows will simply use the 30-00879 harness alone.

Harness Installation Steps
Important Note on Splicing
Cents provides "Insulation Displacement Connection (IDC) Splices" for 18-22 AWG wires. These look as shown below:
See the brief video below to understand exactly how to use these splices:
Always ensure splices are fully seated and used exactly as shown in the video above.
30-00879 Harness
The connectors on the 30-00879 harness can be seen above.
A/V-Series Washer
Though there is a 24VAC transformer on A-Series and V-Series washers, Dexter does not recommend using it to power payment devices. Instead, Cents will supply a 120/240VAC to 24V adapter (81-01613). See the schematic here and a snippet below.
Identify the 115V source on the machine which can be seen at the input of the 24 VAC transformer (typically white and black wires - see the GREEN area in the snippet above). Use the provided splices to connect the two bare wires of the 24V adapter to the input of the transformer.
Connect the male 2-pin on the DC output side of the 24V transformer into the female 2-pin connector on the 30-00879 harness.
Identify the 4-pin coin connector on the control labeled P2, connected to the coin drop (see the RED area in the snippet above).
Remove the 4-pin female connector from the control and plug it into the male 4-pin header on the 30-00879 harness.
Take the female 4-pin connector on the 30-00879 harness and plug it into the control at the header labeled P2.
Verify power by plugging the 16-pin connector into the device.
Once the device has been provisioned, test coin.
N-Series Washer
Dexter N-Series Washers use a "Coin Accumulator" board. The coin drop connects to the this board via a 9-pin connector. A snippet of the schematic is found below, highlighting the coin accumulator (red) and the 120V transformer (purple).
Identify the 115V transformer on the machine. Use the provided splices to connect the two bare wires of the 24V adapter to the input of the transformer.
Connect the male 2-pin on the DC output side of the 24V transformer into the female 2-pin connector on the 30-00879 harness.
Trace two black wires coming from the coin drop into the main machine control board. These are connected to a 9-pin connector on the board. Unplug this connector.
Take the 30-01400 harness and plug the male 9-pin connector end into the female 9-pin connector that was just removed from the machine control board. Take the female 9-pin connector of the 30-01400 harness and plug it into the male 9-pin header on the machine control board.
Take the male 4-pin header on the 30-00879 harness and plug it into the female 4-pin connector on the 30-01400 harness.
Take the female 4-pin connector on the 30-00879 harness and plug it into the male 4-pin connector on the 30-01400 harness.
Verify power by plugging the 16-pin connector into the device.
Once the device has been provisioned, test coin.
A-Series & N-Series Stacked Dryer
N-Series stacked dryers use a 4-pin connector typical to newer Dexter machines. 120V power must be pulled from line power coming into the machine at the control board. See the schematic here, highlighting the coin connector (red) and 120V power (purple).
Identify line power coming into the machine. Trace this power to the main machine controller by identifying a white and black wire.
Use the provided splices to connect the two bare wires of the 24V adapter to the input of the white and black wires, respectively.
Trace two black wires coming from the coin drop into the main machine control board. These are connected to a 4-pin connector on the board. Unplug this connector.
Take the male 4-pin header on the 30-00879 harness and plug it into the female 4-pin connector coming from the coin drop.
Take the female 4-pin connector on the 30-00879 harness and plug it into the machine control board where the coin drop was originally plugged in.
Verify power by plugging the 16-pin connector into the device.
A-Series & N-Series Single Dryer
N-Series single dryers use an 11-pin connector. 120V power must be pulled from line power coming into the machine at the control board. See the schematic here, highlighting the coin connector (red) and 120V power (orange).
Identify line power coming into the machine. Trace this power to the main machine controller by identifying a white and black wire.
Use the provided splices to connect the two bare wires of the 24V adapter to the input of the white and black wires, respectively.
Connect the male 2-pin on the DC output side of the 24V transformer into the female 2-pin connector on the 30-00879 harness.

Take the male 4-pin header on the 30-00879 harness and plug it into the female 4-pin connector on the 30-01334 harness.
Take the female 4-pin connector on the 30-00879 harness and plug it into the male 4-pin connector on the 30-01334 harness.
Verify power by plugging the 16-pin connector into the device.
Once the device has been provisioned, test coin.
A Note on Newer Machines
Most older machines use coin drops with a mechanical switch. Note that some newer machines have been installed with coin drops that use an optical switch. These drops are slightly different and require an extra connector to be connected for full functionality. See a representative schematic here.
In the snippet above, the GREEN highlighted area is the typical coin drop input, labeled P2. This will be connected to the 30-00879 harness as normal and described above.
The RED highlighted area shows the optical coin drop power connector which is a 7-pin connector on the control board. This connector will have two wires populated, red and blue, and will be connected to the coin drop. If the machine in question uses an optical coin drop, it will have this connector which powers the coin drop.
When connecting the Cents harness, disconnect this connector from the control board. Remove the protective cap on the 7-pin connector on the Cents 30-00879 harness in order to expose the 7-pin header.
Plug in the female 7-pin connector from the coin drop onto the male 7-pin header on the 30-00879 harness. Connect the 4-pin connectors and 2-pin connector as described in the appropriate subsection above.
Device Installation Steps
NOTE: optimal device mounting location varies by machine and store. Always ensure that the provided harness length will be sufficient in the selected location.
Devices may be installed in various locations, two of which are shown below (note that the machine shown is not A or N-Series but is extremely similar):
Reference the Dexter C-Series installation guide for specific details.
Device Provisioning
Ensure that the VLAN setup has already been performed in order to move forward with device provisioning.
Follow the generic Penny Installation guide for overall instructions on device provisioning. Shown below are machine-specific provisioning instructions for Dexter N-Series Washers.
Using any smartphone, scan the QR code. A URL with the device's unique ID will be opened. You will be prompted with a login page. Use the provided login. After logging in, a provisioning page for that device will appear.
Washers
For this machine type, copy the settings as shown above:

Minutes per Quarter: Choose from the menu the correct value for how many minutes of dry time that $0.25 purchases on the machine.
After pressing submit, the device will reboot. Each time the device reboots it will display its QR code which can be scanned to verify the settings previously chosen for that device. In the event that a setting was entered incorrectly, contact Cents.
Machine Programming
These machines do not require reprogramming for the successful installation of Cents devices. Do note that devices are not communicating serially with the machine, so the machine vend price must match that which is programmed on the device. If the machine price changes after device provisioning notify Cents and device prices can be changed accordingly.
