Configuring Gen3 Cash Drawer Switch Polarity

Hospitality (HSR) Cash Drawers all use 12V coils with Normally Open detection switches. Gen3 Hospitality platform software defaults its open/close sense settings to this configuration. To use a drawer with Normally Closed detection switches (e.g. Retail 24V drawer), the sense settings can be reversed through registry settings. To reverse the sense settings, follow these steps:

For Cash Drawer 1

1. Create a new DWORD registry value at HKLM/Software/Radiant/Platform/CashDrawer/ReverseOpenDetect1
2. Set the value of the new DWORD to 1

For Cash Drawer 2

1. Create a new DWORD registry value at HKLM/Software/Radiant/Platform/CashDrawer/ReverseOpenDetect2
2. Set the value of the new DWORD to 1
