Noritake Itron has introduced the KBC56A keyboard which is designed to meet a wide range of applications for remote data editing where a conventional keyboard or PC notebook would be too large, inconvenient or expensive to use.
Typical applications include system text editing, product set-up and parameter changes, diagnostics and status readings as well as adding user-advertising to vending, POS and amusement displays. An additional advantage is that users can setup or change foreign language text locally to suit their personnal needs. The 56 keys offer PC emulation capability in a compact ergonomic design with a ten metre range and a low stand-by current of <5uA using two AAA batteries.
The cost of an IR receiver is very competitive and simple to implement at a system or CPU level. Each key is independently transmitted allowing flexibility in the receiver to implement functionality to suit the application. The user can create their own IR receiver or choose one of the receiver modules available which convert the RC5 IR codes into ASCII data and control commands.
Overlays will be available in other languages including Cyrillic (Russian), Greek and Arabic as well as semi-custom options. User software can implement mouse, password and other customised functionality. VFD displays are also available with the IR receiver built-in.
Having investigated wireless, Bluetooth, SMS, memory sticks and PDA's for use on messaging products, it was discovered that wireless suffered from poor reception in metal cabinets and other methods have associated expense or processing overheads. Conventional IR keyboards are relatively expensive, bulky and not easy to operate with one hand when standing up!
If customer's are plugging in a notebook PC or even opening up equipment to change settings, this IR approach can isolate the user from potential static, high voltages or contamination, by using an IR window rather than a plug or socket.
