Dexter: C-series (washers and dryers)
This article covers installation of readers on Dexter C-series washers and dryers. The readers use serial communication and support advanced features like multi-vend pricing, full-cycle dryer pricing, Plus Cycle (e.g Prewash, Supercycle).
Required parts
- Reader (model CR-10-126-02). This includes a special mounting plate that should be installed on the coin-box first
- Cable harness (02-06-78)
Installation Steps
Step 1: Turn Machine Power Off
Step 2: Remove coin-box
Step 3: Number the reader using the DIP switch
See Reader DIP Switch settings article for how to set the DIP switches
Note: For STACK DRYERS specifically!!!One reader controls both the upper and lower pockets on the same dryer stack.
The number that you set using the DIP switches will correspond to the lower dryer; the upper dryer will then assume the lower dryer's number +1.
Therefore, whenever numbering readers for stack dryers, you need to SKIP A NUMBER.
e.g. if you have 2 Stack Dryers, if the 1st reader is numbered as Dryer #1, then the next reader needs to be numbered as Dryer #3 (NOT #2):
On the 1st Dryer stack, you will number the reader as Dryer #1 using the DIP switches.
(the reader will then display the lower pocket as Dryer #1, and upper pocket as Dryer #2)
Then when numbering the 2nd Dryer stack, you will number the next reader as Dryer #3 using the DIP switches.
(the reader will then display the lower pocket as #3, and the upper pocket as #4)
Step 4: Signal Connector
Connect the 4-wire connector to a control board header with a label "SERIAL COM".
Example on Washer
Example on Dryer:
Step 5: Power
Connect the connector with 2 wires to the COIN ACCEPTOR header.
If you installing in a hybrid (coin+card) configuration, see Alternative Power To Reader (in Hybrid) sedction below
Step 6: Mount the Reader
1. Remove coin box if present.
2. Install the mounting bracket (you will need to detach it from the reader first)
3. Mount reader to the bracket
Step 7: Activate Reader
Use the provided Activation card to activate the reader:
Setting Vend Prices
Pricing is controlled by the machine by default - the machine provides the reader with the pricing table over the serial communication link.
However we recommend that you still create Groups (e.g 60lb washers) and put readers into the respective groups as this will allow you to run reports on an entire group.
With newer readers, on Dexter C series Washers only, it's possible to configure the pricing through the reader, via the Laundro Portal.
This will override the pricing set through the machine's controls, so that you can set washer PRICES via the Laundro Portal (wash cycle time still needs to be set on the machine itself).
Please contact support@laundroworks.com if you would like to use this pricing control option.
Troubleshooting
Below are problems commonly encountered during installation of readers on C-series Dexter machines. For more general reader troubleshooting, see https://support.laundroworks.com/portal/en/kb/laundroworkshelp/support-process/readers
Ensure the Dexter C-series washers/dryers are running recent firmware. Otherwise they will not work correctly with the Laundroworks readers.
If the washers/dryers are models from 2021 or earlier, and if the firmware on them has not been updated since then, you will almost certainly need to update it.
| Issue | Explanation and resolution |
| Pricing out of sync | The price displayed on the reader is different from the price displayed on the machine. This happens if you change pricing on the machine and do not reboot the reader. At the present time, the reader only grabs the pricing table from the machine when it boots. So reboot the reader (removing power to machine will reboot the reader) |
| Reader not taking money and not starting the machine | If this is an existing/older machine, the most likely cause is out-of-date software on the machine. Update the machine to the latest software. You'll need a computer and USB stick onto which to copy firmware files. Contact us for help. |
you see "select cycle". When placing a card to the reader, the reader shows the card balance, but won't start the machine | Update the machine to the latest software. You'll need a computer and USB stick onto which to copy firmware files. Then test it again once the firmware has been updated |
Alternative Power To Reader (in Hybrid)
Normally the reader gets 24V from from two pins on the Coin Acceptor header on the Dexter control board. However if you're installing in a hybrid (Coin+Card) configuration, the Coin Acceptor header will likely be used by the coin-drop. In this case, cut the existing connector and connect as shown below
For washers, splice the blue/red wires across the two red wires coming from connector P7
For Dryers, connect the blue/red wires across the blue/white wires coming from the 24Vac transformer. Ideally, modify the reader harness to use female quick-connect connectors and connector to the male connectors coming from the control:
