Use the KeyAT-5 to make an RS-232 connection to
a USB port on a target computer emulating both a
keyboard and mouse. Typical uses are:



Testing Software - Test software input from
simulated keystrokes and/or mouse.



Remote Access – Remote access to systems
where software does not provide other options.



Attaching input devices – Such as bar code
readers, scales, and credit card readers.

Some advanced KeyAT-5 Adapter features are:



Accepts ASCII and Scan Codes

- Accepts printable and

encoded ASCII characters and maps to the correct key.

Also you can send keyboard scan codes



Simple Mouse Control – Mouse movements
and clicks are done with simple commands.



Programmable Keys – You can load a table in
non-volatile flash memory assigning a key or
keys to specific ASCII characters.



Flexible Serial Parameters – You can load the
baud rate and parity settings in non-volatile
flash memory.
