not occur in a particular installation. If the Model 2003 does cause
interference to radio or television reception, which can be determined
by disconnecting the RS-232 or TTL interface, the user is encouraged
to try to correct the interference by one or more of the following measures: moving the computing equipment away from the receiver, re-orienting the receiving antenna, and/or plugging the receiving equipment
into a different AC outlet (such that the computing equipment and
receiver are on different branches).

2.0 APPLICATIONS
Model 2003 allows you to connect an RS-232 or RS485 computer
port to another computer’s keyboard port while still using the keyboard.
Typical applications are for:
•
Software Testing With the help of a Model 2003, you can devel-
op a sequence of keystrokes and send them to the keyboard port
of a computer running the software that you want to test.You can
do this without having to add any software or ports to the comput-
er system you are testing.
• Multi-System testing Using the multi-drop capability of the
Model 2003 keyboard port adapter allows centrally controlled testing of up to 58 systems simultaneously. Only the Model 2003 port
adapter allows such flexibility.
• Remote Access The Model 2003 keyboard port adapter allows
remote access to a system where the software does not provide
any other method.
• Monitoring Ke
yboard Sessions
The Model 2003 can be used
to monitor keyboard sessions. This can be helpful to develop
regression test data or to detect keystrokes that are causing problems with target software. Attach a Keyboard to your Computer's
RS-232 Port - You can use the Model 2003 to send and receive
from a Keyboard attached to an RS-232 port.
