Introduction
The KeyAT-5 keyboard port adapter allows you to
send keyboard keystrokes and/or mouse
instructions to a computer via an RS-232 interface.
Typical uses for the KeyAT-5 are:
Testing software - With a KeyAT-5, you
can send keys and mouse movements that
simulate user input from another computer
using RS-232 communications.
Remote Access - The KeyAT-5 allows
remote access to a system where the
software does not provide any other
method.
Attaching input devices – Allows you to
attach RS-232 devices to the keyboard port
such as bar code readers, scales, and credit
card readers.
Note: The KeyAT-5 also operates during boot mode,
for use with BIOS menus. However, mouse
commands are supported for this use. The Status
command (~?, pg 11) denotes boot or OS mode.

Connections
The following illustrates a typical connection of the
KeyAT-5.
1. The USB connector connects to the target
computer either directly, or via a USB extension
cable, such as L3 Systems part number
CL0017.
2. The RS-232 connector connects to an RS-232
port on the host system either directly, or via an
RS-232 extension cable, such as L3 Systems
part number CL0015.
