About the IB-3 PC Keyboard Wedge
The IB3-PC Keyboard Wedge is a programmable junction box that can stream data
directly from a MS-3 to a host computer program as if the user were typing the data
from a computer keyboard. It is frequently used with older communications devices
lacking serial ports. It can also act as a passive junction box to distribute power, data,
and serial commands.
In the “wedge” mode, it takes 5VDC power from the keyboard PS/2 port of the host
computer and supplies it to the MS-3. The computer’s keyboard plugs into one end of
the wedge and an attached cable with a PS/2 connection completes the connection to
the host.
The wedge has its own CPU and an internal EPROM that can be programmed to emulate
either an AT or XT keyboard. Certain keystrokes can be mapped to create custom out-
puts.
There is a 3-position sliding switch on the wedge. Position 1 is used for the typical
wedge operations. You can also use position 1 for bar code configuration of the wedge
or the MS-3. Position 2 allows serial configuration commands (for wedge or MS-3) to
be entered directly from the keyboard. Position 3 allows serial communication to take
place between the host and the MS-3.
Host Communications
There are two ways the IB-3 PC can be programmed:
1. Serial keyboard commands.
Commands such as <W100?> can be sent from a terminal program, provided
that muting is enabled first by a macro or bar code configuration.
Note: You can learn the current setting of any parameter by inserting a question
mark after the number, as in <K100?> To see all “K” commands, send <K?>.
2. Bar code configuration.

Command Format
Commands to the IB-3 PC Keyboard Wedge follow the same numeric format as those
applied to our bar code scanners except that the IB-3 PC uses a <W...> as a prefix
instead of a <K...>.
Example: <W700,alphanumeric data,more alphanumeric data>
Important: If you want to scan in bar code configuration commands to the IB-3 PC,
you must switch over to Position 1. However, keyboard entry configuration to the IB-3
PC must be done while in Position 2. (See “Serial Operations” on page 3-1.)
Important: Before you can enter serial keyboard commands from position 2 to the
IB-3 PC, you must enable muting with the <W500,1> command. Failure to do this will
result in an endless loop following any keystroke.
There are two ways to enable muting:
1. In switch Position 2, send the macro <W500,1>.
Note: You must send this command as a macro since keying it in will result in an
endless loop that looks like this: <<<<<<<<<<<....
2. In switch Position 1, scan in the Enable Muting symbol:
Once you have enabled muting, you can configure the IB-3 PC in position 2 by typing in
commands or sending macros.
Terminal Connection
You can use Microscan’s ESP (Easy Setup Program) to see configuration commands that
are echoed to your monitor.
To connect with the MS-3 terminal, do the following:
1. Select on Settings in the Connect pulldown menu list.
2. In the RS-232 tab, select 9600 baud, Even parity, One stop bit, Seven data bits.
3. Check Force Connect and click Connect.
4. Connect to the MS-3.
5. Click the Terminal button.

Muting
Important: To avoid an endless loop, always send the Enable Muting command first.
Usage: Muting should be disabled for normal keyboard operations. Muting should be
enabled whenever there’s a need to send serial commands to an MS-3.
Definition: When muting is disabled—as it is by default at power-on or upon a
reset—all keystrokes are echoed to the host. In this mode a command
sent from the host is immediately echoed back to the host and resent in
an endless loop. Muting will interrupt the loop and allow the commands to
take effect.
Serial Cmd: <W500, status>
Default: Disabled
Options: 0 = Disabled 1 = Enabled

Flow Control
Note: If enabled, Xon/Xoff must also be enabled in the MS-3.
Wedge Parameter Default
<W900,DEFAULT>
If the IB-3 PC is not in a known state, it may be
necessary to default it in order to regain desired
functionality. The default communication set-
tings for the wedge are the same as those of a
defaulted MS-3. This assures communication between the MS-3 and the wedge.
MS-3 Default
<W999,DEFAULT>
If the MS-3 is not in a known state, it may be
necessary to default the MS-3 in order to regain
functionality. The default communication settings
for the MS-3 are the same as those of the wedge.
This assures communication between the MS-3 and the wedge.
This command sends an <A> reset to the MS-3 before executing the hardware default.
Note: To take effect, the MS-3 default must be done within 60 seconds after power-on.
Note: Configuring the MS-3 for Continuous-1 is recommended after defaulting.
Definition: Data sizes that exceed the input buffer size (200 characters) can use
Xon/Xoff to manage the flow by sending packets. When enabled, Xon/
Xoff will be sent to manage the serial input.
Serial Cmd: <W810, XonXoff status>
Default: Disabled
Options: 0 = Disabled 1 = Enabled

Save Wedge Parameters
<W200,1>
Once the desired settings have been sent to
the Keyboard Wedge, they need to be saved
to the wedge’s non-volatile memory for
availability on power-on. This command
does this and is similar in effect to the MS-3’s <Z> command.
Packet Status
Packet Start
<W521, Packet Start Char>
When Packet Status is set to 1 the wedge will send data that is prefixed and suffixed
by a char. This command will set the start char. That value is entered as a hexadecimal
value in ASCII that represents that ASCII char value.
Default = “STX” value of #02
Packet End
<W522, Packet End Char>
When packet mode is set to 1 the wedge will send data that is prefixed and suffixed by
a char. This command will set the end char. That value is entered as a hexadecimal
value in ASCII that represents that ASCII char value.
Default = “CR” value of #13
Definition: When set to 0 the wedge will send out keystrokes per each serial charac-
ter that is received at the soonest possible time. When set to 1 the wedge
will send data that is packetized. That means it will only send out the
data in between the start and end packet markers. All other data will be
ignored.

Operations
In addition to its primary wedge use, the IB-3 PC can be also used as a conventional
junction box with serial connectivity to the host and power from a separate power supply.
In this mode, the IB-3 PC is used in place of a junction box such as the IB-131 and
communications between the MS-3 and the host are handled in the same manner
described in the MS-3 Laser Scanner User’s Manual, P/N 83-000003, or the MS-3

Wedge Limitations and Risks
PC's Keyboard Buffer
The PC itself can only handle so many keystrokes in a given period of time. If the inter-
nal workings of the PC do not allow for all the keystrokes to be processed, then they will
begin to pile up within the PC. Eventually the PC will no longer accept keyboard data
and will reject it.
Wedge's Scanner Character Buffer
The Keyboard Wedge has only a finite amount of memory to save incoming serial data.
If the rate of incoming data is greater than the keyboard data leaving the wedge, then
the characters will begin to pile up within the wedge. Either the remaining data is
ignored or a Xon/Xoff protocol will need to be implemented between scanner and wedge
to handle the potential data overflow. The input character buffer size is 200 characters.
If the data that is being sent is larger than 200 characters, it will not be possible to
enable packet mode. Packet mode requires that all data be sent in completion before
the conversion process starts.
Keyboard Activity with Pending Wedge Data
The Keyboard Wedge will buffer data until there are a few milliseconds of quiet time.
Then the Wedge will take over the line and output all the scanner data that is pending.
That means that holding down shift will not work unless the there is enough time
between the keyboard character outputs to allow for the Wedge to splice into the line. If
the wedge does splice into the line, it will ignore any further keyboard activity. There is
a method of accessing the characters that require a shift held to access without the
user actually holding down the shift. See “Momentary Key Bindings” on page A-4.
Held Key Memory Limit
The Keyboard Wedge has a limit of 10 held keys. That means that if there were 11
bound keys (not possible), the last one would be forgotten or ignored.
PC State Changes and Responses
During the Keyboard Wedge data transmission it may be necessary for the PC to change
the capslock LED state. The Keyboard Wedge is responsible for buffering any com-
mands that the PC sends to the keyboard. There is a limit to the amount of data the
Wedge can buffer up from the PC. Typically the amount of data the PC sends is usually
very small. There is also a need to assure that the PC, Keyboard and Wedge do not get
out of sync. This would result in flipping the capslock state.
Continuous 1
For most applications where a symbol only needs to be read once, it is recommended
that the scanner by set to Continuous 1.

Key Mapping Commands
See “Keyboard Layout” on page A-6 and “ASCII Table with Control Charac-
ters” on page A-8.
Momentary Key Bindings
(pushed once and released)
<W700, ASCII_DATABASE_#,ASCII_HEX,KEY#_ASCII_DECIMAL>
There are 10 momentary bindings. These commands range from <W700,1,> to
<W700,10,>.
Held Key Bindings
(pushed once and held)
<W750, ASCII_DATABASE_#,ASCII_HEX >
There are 10 held bindings. These commands range from <W750,1,> to <W750,10,>.
There are 2 occurrences of the bound character to form a Key-ON and some time later
the Key-OFF.
Key Assigning
There are several keys for which there are no assigned ASCII characters. To access
these keys there is a need to assign them valid ASCII characters. To achieve this the
user can send commands to the Keyboard Wedge via bar code programming or RS-232
serial commands from a scanner or a terminal.
There are two types of keys that can be mapped.
• Pushed once and released
• Pushed and held.
Held keys such as Shift, Alt, and Control are examples of keys that need to be held so
that another key will be affected by it. When configuring the Keyboard Wedge the user
should know which keys need to be held and which keys are momentary. Standard
ASCII characters are already handled such as “a” vs. “A”
ASCII_DATABASE_# ASCII_HEX KEY#_ASCII_DECIMAL
The memory slot that
data is to be stored The ASCII value from
scanner The key number based
on the keyboard map
Value (1-10) Value (0x00-0x7F) Value (00-130)
ASCII_DATABASE_# ASCII_HEX
The memory slot that data
is to be stored The ASCII value from scanner
Value (1-10) Value (0x00-0x7F)

Auto Caps Discriminate
These 4 options apply only to “a” through “z”.
Note: Some symbologies do not allow for upper and lower case letters.
Definition: Sets the option for upper and lower case input/output.
Serial Cmd: <W802, auto caps mode>
Default: 0
Options: 0 = Will manage shift for upper and lower case letters
(literal presentation)
1 = Will just send the letter key, ignoring shift/capslock status
2 = Will force all alpha to caps (sends all caps)
3 = Will force all alpha to lower case (sends all lower case)
