Important: This guide applies only to Snackpass-compatible 12V cash drawers.
Legacy 24V models and drawers shipped before November 15, 2023, are not supported and will require a hardware upgrade.
Connection Methods
You can connect your cash drawer using either:
Duo Register (Preferred Method)
Receipt Printer (Alternative Method)
Option 1: Duo Register Connection (Preferred)
1. Connect The Cash Drawer
Plug the RJ12 cable from the cash drawer into the RJ12 port on the bottom of the Duo register's main display.
Note:
Ensure the cable is securely connected.
Handle with care to avoid damaging the connectors.
The cash drawer receives power through this cable—no additional power source needed.
2. Verify Register Status
Ensure the Duo register is:
Powered on
Connected to the internet
Registered to your restaurant in the Snackpass dashboard via Devices > Settings
3. Link The Cash Drawer In Dashboard
Go to the Restaurant Dashboard > Settings > Devices
Select your Duo register and click Edit
Scroll to Cash Drawer Settings
Click + Create, name your cash drawer, and Submit
Under Settings, enable Allow Cash Payments
4. Connect To Cash Drawer
Plug the other end of the RJ12 cable into the cash drawer
No additional power cable is needed—drawer is powered through RJ12.
5. Test The Setup
Run a test order and select Cash Payment
The drawer should open automatically
If it doesn’t:
Double-check all cable connections

Option 2: Receipt Printer Connection (Alternative)
1. Connect The RJ12 Cable
Remove the back cover from your Snackpass receipt printer (Model M30II or M30III)
Plug in the RJ12 cable
Reattach the printer’s back cover
Note:
Use the correct 6-pin RJ12 cable (looks similar to Ethernet but slightly smaller)
2. Connect To Cash Drawer

No additional power cable is needed—drawer is powered through RJ12.
3. Verify Printer Setup
Ensure the printer is:
Powered on
Connected to the internet
Registered in the restaurant dashboard
4. Link The Drawer Via Dashboard
Go to the Restaurant Dashboard > Settings > Devices
Select the receipt printer, click Edit
Scroll to Cash Drawer Settings, click + Create, name the drawer, and Submit

If not, check both ends of the RJ12 connection. Contact support if the issue continues.
Final Step: Cable Management
