On a tumble dryer, find setting "65" and set it to either:
"128" (for a single pulse start)
"192" (for multi-pulse start which allows small increments of time every time you tap the card):
On small-chassis Washers/Dryers, find setting "60" and set it to either:
"128" (for a single pulse start)
"192" (for multi-pulse start on dryers which allows small increments of time every time you tap the card):

Configure the vend price via the LaundroPortal.
The reader sends one pulse to the machine's control board to trigger it to start.

Troubleshooting
Below are problems commonly encountered during installation of readers on these machines specifically.
For more general card reader troubleshooting, see the Card Reader Troubleshoot section of our Help Center.
Issue | Explanation and resolution |
Reader takes money, the machine doesn't start, but the price on the machine goes down by $0.25 | The Card Reader will only sends ONE pulse to the machine, so ensure that the machine is configured to start off of one pulse, by setting the machine's "065" (or "060" depending on the type of machine) setting to equal "128". |
