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 test-
ing 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 Keyboard 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 prob-
lems 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.
3.0 CONFIGURATION
The Model 2003 is easy to install and is ruggedly designed for
excellent reliability. The following instructions will help you to properly
configure the Model 2003.
3.1 CONFIGURATION SWITCHES
The Model 2003 has eight DIP switches that you may use to set
the port address and the bit rate. These externally accessible switches
located on the front of the Model 2003 as shown in Figure 3, below.
Figure 4 shows the orientation of the DIP Switches with respect to
Open and Closed positions.
3.1.1 Address Configuration Switches (S1 through S6)
Switches S1-S6 allow you to set an address for the Model 2003.
You must set an address for each Model 2003 configured in a mul-
tidrop topology. To set a 2003 address, choose an address from the
left-most column of Table 1. Then configure Switches S1-S6 according
to the the OPEN or CLOSED settings in the same row.
