KY2388FR Metal Keypad With LCD and DES TDES Support
KY2388FR combines a metal keypad with a 122*32LCM display in a 128.5*123 mm panel, so a terminal can prompt the user and take input on one part.
Product Overview
KY2388FR combines a metal keypad with a 122*32LCM display in a 128.5*123 mm panel, so a terminal can prompt the user and take input on one part. Display text is customizable over the RS232 interface and the module supports the DES and TDES algorithms. Backlight is available in yellow or green and backlight keys are optional.
- Built-in 122*32LCM display removes the need for a separate prompt screen
- Yellow or green backlight keeps the display readable in poor lighting
- DES and TDES algorithm support for protected data entry
- RS232 interface lets a controller drive the display text directly
- IP65 approval suits outdoor parking and fuel forecourt installations
- Square 128.5*123 mm panel simplifies the fascia cut-out

Application Scenarios
- Oil and gas forecourt payment points
- Parking entry and payment terminals
- Vending machines with on screen prompts
- Industrial automation operator input stations
- Transportation and automotive service terminals
- Pharmaceutical, medical and healthcare access points
Who It Is For
- Parking and fuel payment terminal OEMs
- Vending machine manufacturers
- Industrial automation panel builders
- Healthcare and pharmaceutical equipment suppliers
Problems It Solves
- A keypad without a display forces a second cut-out and cable run
- Entry of protected data needs algorithm support rather than plain text
- Fascia mounted displays wash out in daylight without backlight choice
- Outdoor terminals need sealing and approvals that office parts cannot meet

How It Compares
| Metal keypads without a display | KY2388FR carries a 122*32LCM display so prompts and entry share one panel and one cut-out. |
|---|---|
| Plastic LCD keypads | The metal keypad with LCD is IP65 approved for outdoor parking and forecourt exposure. |
| Keypads without algorithm support | KY2388FR supports DES and TDES for protected entry applications. |
Use Guide
- Cut the fascia for a 128.5*123 mm panel and choose rear or front mounting
- Connect RS232 to drive the display text from your controller
- Confirm backlight colour and display content before final assembly
- Maintain gasket compression so the IP65 rating holds outdoors
- Operate within -10℃~55℃ ambient
