Coin-Op Retrofit · Self-install kit

Installing the SnackHoot bridge module

The Coin-Op Retrofit is a self-install kit: a SnackHoot QR sticker plus a bridge module you install in your own machine. Here is what installation generally involves.

General guide — kit-specific instructions ship with the module. Where your kit card differs from this page, follow the kit card.

Safety first

Unplug the machine from the wall before opening it, and keep it unplugged until step 4.
Don't modify the machine's mains (wall-power) wiring. The bridge module only connects to the low-voltage coin mechanism harness.
Check your machine's warranty or lease terms first. If you're unsure about any step, use a qualified vending technician.

Unplug the machine and open it.
Switch off, unplug from the wall, then unlock and open the door.
Find the coin mechanism harness.
On most machines it's the MDB 6-pin connector going to the coin mech. The kit supports standard coin machines with this connector.
Install the bridge module.
Plug the bridge inline between the machine controller and the coin mech.
Connect power to the module.
Use the power connection described on your kit card, then close up any wiring so it can't be pinched by the door.
Stick the QR sticker on the front.
Clean and dry the spot first, at eye level near the selection panel, where customers can scan it easily.
Power on and pair.
Plug the machine back in and switch on. Pair the module in the SnackHoot app using your machine code.
Run a test vend.
Buy one item and check it shows up correctly in SnackHoot. If it doesn't, power off and recheck steps 2 to 4.
