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.
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 multidrop 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.

3.2 CONFIGURATION STRAPS
In addition to the configuration switches described above, the
Model 2003 also has two internal straps: One that set the RS-232 or
RS-485 Operation; and, one that determines whether the keyboard
connection passes through the 2003, or connects between devices in
parallel. In order to configure these straps, you must open the Model
2003 case.
NOTE: Before opening the case, determine whether the default
settings are correct for your application (see Sections 3.2.3 and
3.2.4)
3.2.1 Opening the Case
To open the Model 2003 insert a large flat head screwdriver into
an open slot on either side of the case, as in Figure 5.

4.0 INSTALLATION
The Model 2003 is typically installed by connecting the DB-25 port
to a computer or terminal, the keyboard port to a keyboard, and the
computer port to a computer’s keyboard port. This section describes
connection procedures.
There are three data ports on the rear panel of the Model 2003 -an RS-232/RS-485 female DB-25 port, a Keyboard port, and a computer port (see Figure 9, below).
4.1 CONNECTING RS-232/RS-485 DEVICES
When the DB-25 port of the Model 2003 is configured as an RS232 port, it looks like DCE (Data Circuit-Terminating Equipment).
Therefore, the Model 2003 serial port will connect directly to a DTE
(Data Termination Equipment) The following pinout diagram shows the
signal directions of the pins on the interface.

4.2 CONNECTING THE COMPUTER/KEYBOARD PORTS
To connect the computer and keyboard’s ports, follow these steps:
1. Connect the keyboard’s 6-Pin Mini-DIN connector to the keyboard port on the Model 2003.
2. Connect the enclosed 6-Pin Mini-DIN cable between the por t
labeled “Computer” on the Model 2003 to the Target PC’s
Keyboard DIN port.
5.0 OPERATION
5.1 COMMAND/DATA ENTRY
The Model 2003’s main job is to accept data from the RS-232 or
RS-485 port and send it through to another computer's keyboard port.
However you may also enter configuration commands to the Model
2003. You may send data or commands in the following forms:
1. ASCII;
2. ASCII control codes;
3. DOS scan codes;
4. Keyboard scan codes;
5. ASCII Hexadecimal.
Commands are instructions to the Model 2003 to do something
other than just pass data through to the computer. All commands
begin with a ~ (tilde, hex 7E) character followed by a command character and in some cases, some data.
: ~C<ENTER> {Sets Model 2003 to Character Mode}
: DIR^M<ENTER> {Sends DOS a directory command}
5.1.1 Command Entry Rules
Commands have some restrictions based upon the Model 2003
operating Model (See Section 5.2 for Operating Modes). These rules
are listed below:
Rule #1.
You may string commands together in one command
line, and separate commands with spaces. This will occur before
you press <ENTER/CR>.
Rule #2.
Each command line must end with an <ENTER/CR>.
The Model 2003 will not begin command execution until it receives
a carriage-return character.
Rule #3. If you turn on line tur n around (~L Command) or set an
address on the Model 2003 if the Model 2003 is addressed, a line
can have a maximum length of 46 characters and should end with
an <ENTER> (CR, hex 0D).
Rule #4. In the case when immediate tur n around is set, data and
commands are interpreted as received, and buffered up to 30
characters.
Rule #5. If you get more than 30 characters ahead of the computer, the additional characters will be tossed.

Rule #6. Characters are not echoed when the Model 2003 is
addressed.
Rule #7. If line tur n around is set or if the Model 2003 is
addressed, a colon is sent back acknowledging the data sent.
Rule #8. After receiving an addressed message, a colon is sent
back immediately.
Rule #9. If not addressed but line turn around is set, a colon is
sent back after the data has been processed, signaling that another command can be sent.
5.2 OPERATING MODES
Four operating mode commands set the way Model 2003 interprets incoming data. Once set, the Model 2003 operating mode stays
the same until you change it or until a power failure occurs.
~C Character Mode - is the default mode of operation. When
this mode is set, any ASCII character except ~ (tilde, hex 7E),
^ (caret, hex 5E), and CR (return, hex 0D) is converted to the
scan codes for that character. Each ASCII character will be
sent to the keyboard with the corresponding make and
release codes. Allow enough time for the codes to be sent
through to the computer, as an ASCII code can require up to
10 keyboard codes to execute.
(default operating mode)
Control codes may be sent by a combination of a ^ (caret, hex
5E),a nd the corresponding letter. For example, a control C
(Hex 03) is ^C.
~H Hex ASCII Mode - Data is interpreted as hexadecimal encod-
ed ASCII. For example, to send the computer the character
‘A’, you would need to send its hexadecimal ASCII value (Hex
41) as two ASCII digits, 4 and 1.
~S Scan Code Mode - In this mode, date is translated to the cor-
responding keyboard scan codes. For an ASCII transfer, each
pair of ASCII encoded characters is interpreted as a DOS
scan code. For a binary transfer, each 8 bit character is interpreted as a DOS scan code. DOS assigns each key a DOS
scan code. Note that all DOS scan codes are sent complete
with make and break sequences.
~K Key Code Mode - In this mode, codes are sent directly to the
computer without interpretation. For an ASCII transfer, each
pair ASCII encoded characters is interpreted as a keyboard
code. For a binary transfer, each 8 bit character is interpreted
as a keyboard code. Care should be taken in using keyboard
scan codes, as the computer can be left in a very confused
state if the scan code sequence is not properly completed.
5.3 DATA TRANSFER COMMANDS
~A ASCII Transfer - Default setting. If ASCII transfer is set, all
data is interpreted as ASCII.
~B Binary Transfer - In scan code (~S) or key code (~K) modes.
Data is sent as 8 bit binary
5.4 KEYBOARD COMMANDS
~Dnn Set/Clear Keyboard LEDs - Use this command to turn on or
off local keyboard LED indicators. The nn field is an ASCII
hex encoded binary field, where:
b0 = Scroll Lock
b1 = Num Lock
b2 = Caps Lock
Examples: ~D01 Scroll Lock on, Caps & Num Lock off
~D04 Caps Lock on, Scroll & Num Lock off
~D00 Turns off all LEDs
~Xnn Send Data to Keyboard - Use this command to send the
ASCII hex encoded byte nn to the keyboard. This command
requires technical knowledge of the keyboards.
5.5 TURN AROUND COMMANDS
~I Immediate Turn Around - Data is interpreted ‘on-the-fly’.
Special address switch setting of 59 makes this default for
non-addressed mode. Note that in this mode <ENTER/CR>
(Hex 0D) is not a special character, and passed on to the
computer.
~L Line Turn Around - Set Model 2003 to a line oriented basis,
each line ending with an <ENTER/CR> (Hex 0D).
19 20
~Pnn Set Turn Around Delay (nn milliseconds) - This sets the
delay that the Model 2003 waits before sending data in
response to a command. The default setting in nonaddressed mode is 0, and in addressed mode the default setting is 3 milliseconds. (NOTE: You must send two digits, i.e.
for 7 milliseconds, send ~P07)
5.6 KEYBOARD MONITOR COMMANDS
~M Monitor ON - Turns keyboard monitor on
~N Monitor OFF - Tur ns keyboard monitor off
5.7 OTHER COMMANDS
~T Test Model 2003 - This command to the Model 2003 causes
it to undergo tests to validate the keyboard and computer
interface. You will see the keyboard LED’s cycle, testing the
keyboard interface. You should see on the PC screen:
TEST:7 (With the number cycling from 0-7)
The serial port displays:
Test: <ENTER> to stop
The test runs until <ENTER> is received.
~? Request Status - The format of the response is:
AA-EEDDMBTV where
AA is the address setting
- is a dash character, Hex 2D
EE is a error status:
00-No Errors 01-Parity Error
02-Framing Error 03-Parity and Framing
DD LED status (bit field -0=OFF, 1=ON
b0-Scroll lock b1=Num Lock b2=Caps
Lock
M Mode setting (~C, ~H, ~K, or ~S)
B Binar y or ASCII Transfer Setting (~A or ~B)
T Turn Around Setting (~I or ~L)
V Monitor Setting (~M or ~N)
5.8 MULTIDROP OPERATION
If the DIP switch address setting is not zero, Model 2003 looks for
an address select prefix to any buffer received. The address must be
the first byte of the transmission and the high bit set. Address 1 is hex
81, Address 2 is hex 82, etc. If you send a command to address 80,
all Model 2003s will read the command.
When sending data to the Model 2003 in multi-drop mode, the
Model 2003 will return a single byte colon character when it receives
the message. This does not mean that you can send another buffer
can be sent but rather that the Model 2003 received the message and
the host can go on to talk to other devices. If a proper delay cannot be
assured, you should poll the device until it responds before sending
another buffer.
5.9 LED INDICATORS
The Model 2003 features three front panel LEDs that monitor data
activity on the keyboard and RS-232/RS-485 ports. Figure 10 shows
the front panel location of each LED. Following Figure 10 is a description of each LEDs function.
Keyboard Turns solid yellow when the keyboard is
sending to the Computer. Blinks whenever
the Model 2003 is processing a command
from the RS-232/485 port. If Model 2003 is
set with an address, the LED blinks yellow
when it receives its address.
Receive Blinks red when Model 2003 receives data
or commands on the RS-232/RS-485 port.
Transmit Blinks green when Model 2003 transmits
data through the RS-232/RS-485 port.
