F.A.Q’s 

 

Does this encoder need a special driver ? 

 

 

No – it works with the standard USB keyboard driver 

Does the utility work on any pc ? 

 

 

 

At present it does not run on Linux or Mac os 

 

 

 

 

 

 

 

 

The utility requires Windows XP or later 

What’s the USB connection ? 

 

 

 

Mini-B socket 

Do I need to use the sticky pads ? 

 

 

 

These are included to retain the encoder in service 

What custom USB codes can I assign ? 

 

 

See the code tables on page 11 

What do I do if I have wrongly initialised the product ?  

Download & use the config utility to reset the defaults 

Why is the socket longer than the pinstrip on my keypad? 

The end pins power the 720 illuminated keypads. 

Can I control this from a host application ? 

 

 

Yes – the commands are listed in the API reference
