Introduction to the KE72

The KE72 Keyboard Encoder is a product designed to interface 
switches or keypads to the computer’s PS/2 keyboard port. The 
KE72 appears as a keyboard to your computer system (and also 
a mouse with the KE72-T). The response to the activation of any 
of the 72 Individual inputs on the KE72 may be programmed 
to emulate a key or sequence of keys found on a standard PC 
keyboard. 

The KE72-T features a trackball interface port which allows 
connection of the optical signals from a trackball to the unit. The 
signals received on this port are converted into mouse movement 
on the PC.

The KE72 uses standard drivers for its functions. No special software 
is required for the unit to work with your PC. Once programmed, 
the KE72 can be used with any PC compatible operating system.
