Introduction
The Zebra Keyboard Display Unit
2
The Zebra Keyboard Display Unit
The Zebra Keyboard Display Unit (ZKDU) is a terminal unit that interfaces with Zebra
label printers in a standalone capacity.
The ZKDU is designed to print pre-stored forms (print layout formats) in Zebra label
printers that support EPL (EPL2) or ZPL (ZPL II) label format programming languages.
Some Zebra label printers have EPL (only), some ZPL (only), and some later model Zebra
label printers that simultaneous support both ZPL and EPL printer languages. Depending
upon the print form’s format, the operator can be prompted via the form’s data entry
format and the ZKDU’s form access and print controls to enter data, serial numbers,
reprint quantity, and batch print quantities.
The ZKDU has sixty-two (62) keys and a 2-line, 20 character LCD display. The ZKDU is
powered by and communicates with the printer through an RS232 serial port with a DB-9
(standard printers). The ZKDU includes a low current auxiliary serial port for attaching a
scanner, scale or other peripheral devices. The ZKDU has been designed to interface with
many Zebra label printers that support EPL2 and ZPL II Zebra printer programming
languages.
The ZKDU is strictly a terminal and does not have the capability to store data or configure
ZKDU or printer parameters. The ZKDU is used for the following functions:
• List label forms stored in printer
• Retrieve label forms stored in printer
• Input variable data
• Print labels
• Switching between EPL and ZPL to dual support both language form types that can
be stored and printed in many of later model Zebra label printers
The ZKDU is designed as a direct replacement for the Zebra KDU (Keyboard Display
Unit) and the KDU Plus as a functional replacement when operating in Forms mode. It
does not support terminal, setup, or file modes of the KDU Plus. See the Zebra Website for
the new, existing and legacy label printers supported by the ZKDU, KDU and KDU Plus
keyboard display units.
The ZKDU features automatic printer configuration detection of:
• The Zebra label printer’s serial port type (DTE or DCE). Eliminates the need for
cable adapters used with some printer models and the KDU.
• The ZKDU tests and configures communications and forms processing to match the
printer’s default label printing language: EPL or ZPL.
The ZKDU has limited language locale support. It supports the EPL keyboard character
variations based on the printer’s language code page and region setting. For EPL forms,
Zebra has included keyboard overlay strips for use with one of 14 different locales
supported by the printer’s EPL
For a list of Zebra label printers supported by the ZKDU, see the following Zebra Website

ZKDU Keyboard Controls
The ZKDU has a QWERTY style keyboard that includes special function and navigation
keys to allow the operator to control form access, data entry, set print counts, and printing.
The white character keys are the valid characters allowed in form names for both EPL and
ZPL formats. The white arrow keys are not valid characters, they are for navigation only.
After the ZKDU has finished it’s startup routine, the printer displays the FORM recall
screen. The only keys that are active during this time are the FORM , F1 , and F2 keys.
FORM key - Print Form request. Pressing the “Form” key causes the ZKDU to display
the forms request prompt. Valid Form names for the ZKDU are up to eight (8) characters

ZKDU Data Entry
The ZKDU has three types of data entry and display data:
• ZKDU Keyboard
• Peripheral device attached to the Auxiliary port on the ZKDU (i.e. scan gun, wedge
device, etc.).
• Zebra ZKDU compatible printer’s Form interaction controls including operator
messages (prompts, default values for printing, serial numbers, etc.) can interact and
fill in data.
The maximum number of characters that can be entered from one data entry (prompt) is
160 characters. The display can only show 20 characters at one time. The  (LEFT
and RIGHT) arrow keys are used to view and position the cursor (prompt). Data can be
replaced or deleted where the cursor is positioned.
Keyboard Data Entry
The operator can enter
• A-Z, a-z, 1-9, , /, $, %, ½, ¼, *(asterisk), # (number sign), space ( ), comma (,), and
period (.) are valid characters for use.
• EPL printers have the ability to interact with the ZKDU to change the language
character code page and provides for different characters needed for data entry
based upon language (code page) and locale (country) setting.

Setup
Basic Hardware Installation
10
The ZKDU has three (3) basic requirements for connecting and using a Zebra Label
Printer with the ZKDU for the first time:
• ZKDU Compatible Zebra Label Printer - See the Zebra Website for a list.
The ZKDU requires a fully functional Zebra label printer running EPL (EPL2),
ZPL (ZPL II), or dual mode EZPL (EPL and ZPL) print operations.
• The Zebra label printer must have the Serial Port communications set to:
9600 baud, 8 bit word length, NO parity, 1 stop bit, and Hardware (DTR/DSR)
data flow control.
• Compatible media for your Zebra label printer and your print job (the label forms
you will print). See the printer’s user and programmer manuals or guides for details
about programming, Window’s printer driver, and other tools available.
Setting the Printer Up
1. Connect the printer to power. With the printer power off, attach the printer to power. A
Zebra TLP2824 Plus desktop label printer is shown for reference only. Your particular
Zebra printer may have an internal power supply. See your users guide for more
details.
2. Connect your chosen Zebra label printer up to a PC with the Zebra Windows printer
driver installed for your printer. Establish communication to the printer via one of the
printer’s other non-serial port interface connections, i.e. USB, parallel, Ethernet, etc.
The serial port will be used for ZKDU operations.
3. Load your selected media in the printer. Use the Windows printer driver to set the
media parameters and do a test print. The printer should be set for the media type and
size in use, i.e. set it for continuous roll or label/tag/ticket with gap, notch or black
mark/line. The media type and size (length and width) should be set and stored in the
printer via appropriate programming commands or the Windows printer driver.
Note • Thermal transfer media requires ribbon to print, direct thermal media does not.

11Setup
4. From here, Print Forms can be developed for storage to later be accessed and printed
with the ZKDU in a stand alone capacity (not connection to PC or host computer).
Do not connect the ZKDU to the printer until the printer’s serial port is configured.

Setup
12
Configuring the Printer Serial Port
Zebra label printers have a variety of different default serial port configurations and may
have been modified by previous uses. If you are using a Windows based computer, the
Zebra Setup Utility and ZDesigner Windows driver have various tools to allow you send
files and commands to the printer.
1. Open the your Zebra label printer’s Windows printer driver.
2. Open the Tools tab. Select ‘Action’ and ‘Send command’.
3. Enter one of the two (2) following command strings in the command input box and
press the ‘Send’ button.
For EPL only printers:

13Setup
First Use - Testing the System
Lets review. We have:
• Setup the printer and configured it for your selected media.
• Performed a test print using the Windows printer driver.
• Set the printer’s serial port for ZKDU communication.
• Optionally created one or more print forms and downloaded them into the printer.
The ZKDU and printer are now ready to be joined to become a stand alone print system.
Use the following steps to complete the ZKDU print system’s setup and print a list of the
forms stored in the printer.
1. Turn the printer’s power off.
2. Disconnect any other printer communication cables from the printer (used to
configure printer and develope print forms).
3. Connect the ZKDU serial cable to the printer’s serial port and secure the cable with
the thumb screws. (Printer shown for reference only, you may have a different model).
4. Turn the printer power on.

5. The ZKDU (and the attached printer) will begin initial internal testing. The ZKDU
will then automatically detect the serial port configuration of the attached printer. The
ZKDU finishes with testing for EPL print capability first, then tests for ZPL print
capability, and if neither Zebra programming language is detected - an error message
is displayed.
6. Press the F2 key to print a list of Forms stored in the printer. See examples below.
7. Some Zebra label printers support dual EPL and ZPL programming and can have both
Form types present in printer memory. Use the F1 key switch between language
modes and then use the F2 key to print a new list of Forms that design for the other
programming language.

EPL ZKDU System
Unique ZKDU EPL Features
16
Unique ZKDU EPL Features
The ZKDU was designed to replace the original Zebra KDU. The KDU was designed to only
operate with a Zebra label printer with the EPL programming language. All the form
interaction was controlled by the printer and the form’s unique programming. The EPL printer
processes and passes only operator input data and prompts between it and the ZKDU. All
form prompts and form data are stored in the printer (and by implication limited only by
printer memory). The ZKDU duplicates the original KDU’s operations.
The ZKDU operating in EPL mode:
• Form Names are case sensitive and are limited to 8 alpha-numeric characters.
(ZPL form names are not case-sensitive).
• Supports up to 100 Variables, 10 (Numeric) Counter Variables, and unlimited use of
the printer optional RTC (Real-Time Clock) Date and Time Variables.
• Starting values for counters can be set by ZKDU operator prompt. ZPL doe not sup-
port this feature.
• The EPL prompt is limited to 40 characters, but only 20 characters can be displayed
in the top row of the ZKDU display.
• The EPL enabled printer reserves a minimum of 3000 bytes (ASCII -non-hexadeci-
mal) for storing operator responses to multi-copy form prompt replies. Each charac-
ter is a byte. Legacy EPL printer models with cartridge memory have 1500 bytes as is
documented in the EPL programmer’s manual.
• A single print job can have up to 9999 unique print images (for serial number and
operator input) with up to 9999 copies of each unique printed image. For example,
you can print 3 copies of the same unique serial number label and print 5 sets of
those serial number label copies for 15 total labels.
• Runs slightly faster and has fewer memory limitations than ZPL mode.
• Supports multiple language locales. The EPL enabled printer supports codepages
and alternate keyboarding techniques to provide for language character and cur-
rency symbols variations for printing print formats designed for use in North and
South America, and many European locales and languages. In contrast, the ZKDU
only supports the ZPL enabled printer’s default language locale codepage in ZPL
mode. See Configuring Language Locales for the ZKDU on page 20.
Important EPL Commands for Operator Interactive Print Forms
The following EPL commands can be used to add operator prompts and variable data to
control print output with the ZKDU. See the EPL programer’s manual for details.
• PA - Command: Print Automatic - Controls print quantities (sets) and number of
reprints (copies of each set member)
• V - Command: Define Variable - Creates data input variables and user prompts
• C - Command: Counter - Activates counter variables for sequencing numbers. Can
be used as PA command parameters.
• ? - Command: Download Variables - Listed here for reference. The ZKDU sends a
Form Recall followed by this Download Variables command to begin operator
prompts and data input. The ? - Command is shown in several programing exam-
ples for other commands and can provide insight into the operation of the ZKDU.

17EPL ZKDU System
EPL Mode ZKDU Use Example
Use the following steps to retrieve label form and produce labels with the printer and ZKDU.
1. Start Up - After the ZKDU has finished it’s startup routine, the printer displays the
FORM recall screen.
2. List of Saved Forms - Press the F2 key to print a list of saved forms.
3. Retrieve a Form - Press the FORM key. The top line in the display will prompt:
Enter the Form name using the keys on the keyboard. Upper and lower case letters must
match exactly as the form name was saved. Tip: If a scanner is connected to the ZKDU,
you may enter the Form name by scanning it in from a pre-printed barcode.
When the Form name is entered, press ENTER to continue. The form is now retrieved
and active in the printer.
Printing Forms without Variables
If the form does not contain variables, the display line will prompt:
The default number of label sets is always one (1). Entering a different number(s) will
overwrite the default value. Non numeric values will be ignored with an error beep. This
prompt is supplied automatically by the ZKDU.
Single Label - If one (1) label is desired, press ENTER to print that label.
Multiple Labels - If multiple labels are desired, enter the new quantity and press ENTER to
print labels.
Exit a Form - Press the EXIT key at any time to return to the Forms screen, or press the
FORM key to select another form.

EPL ZKDU System
18
Printing Forms with Variables
If the Form contains variables, the display line will display the 1st variable prompt (as
programmed ‘Total No. of Boxes’), i.e.:
Enter data at each variable prompt and press ENTER . The final prompt is:
The default number of label sets is always one (1). Entering a different number(s) will
overwrite the default value. Non numeric values will be ignored with an error beep. This
prompt is supplied automatically by the ZKDU.
print labels.
Printing Forms with Consecutive Number Fields
If the Form contains a consecutive number (C - Command: Counter) field, the system will
automatically keep track of the next number sequence. If you do not need to interfere with this
predetermined sequence, press ENTER at this prompt. The final prompt is:
The default number of copies is always one (1). The default number of labels is always one
(1). If one (1) copy is desired, press ENTER to print that label. Entering a different
number(s) will overwrite the default value. Non numeric values will be ignored with an error
beep. This prompt is supplied automatically by the ZKDU.
Note: Change the quantity if you desire multiple labels with the same consecutive number.
Edit Form Data - Once a Form has been activated, it will automatically indicate the last
information keyed in. If you want to retain that information, press ENTER .

19EPL ZKDU System
To Enter Data:
1. Enter the new input data, thereby overriding the previously entered input data for that
variable, or
2. Press ENTER if the previously entered input data is correct, or
3. Use the orange  Backspace key or the CLEAR key to modify data. Enter new data
at the cursor prompt and press ENTER to complete overwriting previous form data.
When you have finished editing and have printed the label, you will automatically return
to the first variable prompt of this Form.
Forcing the Operator to Re-enter Variable Input Data
If the operator prompt parameter has a ‘Tilde’ (~) character as the first character of the prompt
string, then the input data (second line on the display) needs to be entered every time it is
displayed. The ‘Tilde’ character does not display.
Protecting Operator Variable Input Data
If the operator prompt parameter has a ‘Minus Sign’ (-) character as the first character of the
prompt string, then that data will be ‘protected’ and will not reappear until the Form has been
exited and recalled from the printer as a new print job. The ‘Minus Sign’ character does not
display when in the first position.

EPL ZKDU System
Configuring Language Locales for the ZKDU
20
The ZKDU supports printer language locale with the EPL alternate language select by A
programming method to support character differences by locale. Character overlays are
available to identify the changed characters for data entry. The default EPL language setting
for language and locale support is Code Page 437 for English-USA. The ZKDU keyboard has
been design to support this configuration. The ZKDU can support other languages and listed in
this section.
The language settings for EPL printing operation is set with the I - Command. The ZKDU
only supports printing and displaying with a subset of the languages and locales that the EPL
print operations can support.
The I - Command structure matches the following:
I8,Code_Page,Country_Code
The EPL printer default setting for language and locale setting is the equivalent of the
following I - Command programming string:
I8,0,001
It is for the U.S. English Code Page 437 with the ZKDU/KDU country set for the USA (-001).
ZKDU EPL Supported Language Code Pages
The following code pages support both the ZKDU and EPL printers. Please reference the EPL
Programming Guide to verify the character sets available for printing. The ZKDU supports
data entry and displaying a large subset of each of these code pages.

Adding the Keyboard Overlay to the ZKDU
The ZKDU has fourteen (14) keyboard overlay strip pairs to support sixteen (16) language and
locale (Country Code) settings in the EPL printer.
• Use the United Kingdom (Code 044) strip pair for the South Africa (Code 041)
printer locale settings.
• Use the Sweden (Code 046) strip pair for the Finland (Code 358) printer locale set-
tings.
• All other Country overlay pairs are marked on the overlay sheet.
Place the two character strips as shown below. The first strip gets placed above the top row
starting at the ‘plus’ sign key. The second strip gets placed above the ‘½’ character key.
Entering the Alternate Characters for Display and Print
The operator can use the overlay to select the language/locale unique code page characters by
pressing the key immediately below the desired overlay character while also pressing the shift
key. For example, if the EPL printer has the language code page set to value ‘1’ to support
code page 850 for Multilingual (Latin 1) and the ZKDU country code set to ‘032’ for Belgium,
then by typing the ‘Plus’ sign (+) key immediately below the ‘é’ overlay character while
pressing on the shift key, you will enter a ‘é’ into the data input and display it at the prompt on
the ZKDU screen.

ZPL ZKDU System
Unique ZKDU ZPL Features
28
The ZKDU was designed to emulate the basic Form processing operations of the Zebra KDU
Plus. ZPL Print Forms are imported and processed by the ZKDU. The ZPL form is parsed to
extract operator data entry parameters and prompts. The ZKDU passes only operator input
data to the printer to fill-in form variables. All form prompts and form input data are
temporarily stored in the ZKDU while processing the recalled form.
The ZKDU operating in ZPL mode:
• ZPL Form Names are limited to 8 alpha-numeric characters and are not case sensi-
tive. (EPL Form Names are case sensitive).
• ZPL Forms must be stored in the printer’s E: memory to be accessed by the ZKDU.
• Supports Field Variables, Serial Number (Alpha-numeric Counter) Fields (not sup-
ported as a variable), and printer optional RTC (Real-Time Clock) Date and Time
Variables.
• The ZPL prompt is limited to 255 characters, but only 20 characters can be dis-
played in the top row of the ZKDU display.
• 1024 bytes are reserved for ZPL form variables prompts and operator input data in
the ZKDU. The KDU Plus only supported 576 bytes for this feature.
• A single print job can have up to 99,999,999 unique print images (for serial number
and operator input) with up to 99,999,999 copies of each unique printed image. For
example, you can print 3 copies of the same unique serial number label and print 5
sets of those serial number label copies for 15 total labels.
• Language and locale support is limited primarily to the lower half of the Zebra
Codepage 850 (decimal 32-127), the printer’s default character set. The ZKDU and
printer in ZPL mode will display and print all the characters on the ZKDU key-
board. Data input made via a peripheral device (such as a scanner) attached to the
ZKDU’s auxiliary port or sent as form prompt data may not display correctly or will
be replaced by a space.

29ZPL ZKDU System
ZKDU Internal Forms Processing Memory
The ZKDU has 1024 bytes reserved for ZPL form variables prompts and operator input
data in the ZKDU. The memory is filled with operator prompts from one end and the
operator responses to the prompts are stored starting at the opposite end. Form prompts
get stored first, then as the form is run, the operator input data is sent to the printer and the
ZKDU memory.
If the available memory for storing all of a form’s variable and their prompts is exceeded,
then it will display the following error message:
The total number of bytes used to store variables (and their prompts) of a ZPL form in the
ZKDU is the total number of characters in the prompt plus seven bytes overhead. Each
character is equal to a byte of data. If each prompt in a ZPL form were twenty (20)
characters, then a total of 37 variables can be supported, i.e. (20 + 7) x 37 = 999 bytes
which is less than the 1024 max. bytes of ZKDU temporary form storage.
Left over memory from variable prompt (and pointer) storage is used for storing the
operator input data (responses to prompts). This input data is used to pre-populate operator
responses for subsequent form print entries. If 1024 bytes are exceeded during data entry,
the ZKDU will clear the oldest previous value entered and continue the data entry process
and store the new value. If the new value exceeds the storage limit, then the value will not
be saved for the next iteration of the form.
ZPL Commands for Operator Interactive Print Forms
The following ZPL commands can be used to add operator prompts and variable data to
control print output with the ZKDU.
• ^PQ - Command: Print Quantity - Controls print quantities (sets) and number of
reprints (copies of each set member)
• ^FN - Command: Field Number - Identifies data input variables and provides user
prompts
• ^SN - Command: Serialization Data - Used to provide alpha-numeric incrementing
or decrementing data fields. Starting index (count) values must be build into the
form’s format, it can not be added as a variable using the ^FN command.
• ^FV - Command: Field Variable - Do Not Use In ZKDU Form. ^FV is designed
for use with process chained forms.

ZPL ZKDU System
ZPL Mode ZKDU Operator Usage Examples
30
Use the following steps to retrieve label form and produce labels with the printer and ZKDU.
1. Start Up - After the ZKDU has finished it’s startup routine, the printer displays the
FORM recall screen.
2. List of Saved Forms - Press the F2 key to print a list of saved forms.
3. Retrieve a Form - Press the FORM key. The top line in the display will prompt:
Enter the Form name using the keys on the keyboard. Tip: If a scanner is connected to the
ZKDU, you may enter the Form name by scanning it in from a pre-printed barcode.
When the Form name is entered, press ENTER to continue. The form is now retrieved
and active in the printer.
Printing Forms without Variables
If the form does not contain variables, the display line will prompt:
The default number of labels is always one (1). Entering a different number(s) will overwrite
the default value. Non numeric values will be ignored with an error beep. This prompt is
supplied automatically by the ZKDU.
print labels.

31ZPL ZKDU System
Printing Forms with Variables
If the Form contains variables, the display line will display the 1st variable prompt (as
programmed ‘Total No. of Boxes’), i.e.:
Enter data at each variable prompt and press ENTER . The final prompt is:
The default number of labels is always one (1). Entering a different number(s) will overwrite
the default value. Non numeric values will be ignored with an error beep. This prompt is
supplied automatically by the ZKDU.
print labels.
Printing Forms with Consecutive Number Fields
If the Form contains a consecutive number (^SN - Command: Serialization Data) field, the
system will automatically keep track of the next number sequence. Enter data at each variable
prompt and press ENTER .
The first form finishing prompt is:
This value represents the total number of labels to print. The default number of labels is
always one (1). Entering a different number(s) will overwrite the default value. Non numeric
values will be ignored with an error beep. This prompt is supplied automatically by the ZKDU.
(This varies from EPL mode operations which specifies label sets, not total labels to print).
The total number of labels (1st form finishing prompt) should be a multiple of the number of
copies of each serial number (2nd form finishing prompt - the next step in the process).

ZPL ZKDU System
32
The second form finishing prompt is:
The default number of copies is always one (1). If one (1) copy is desired, press ENTER to
print that label. Entering a different number(s) will overwrite the default value. Non numeric
values will be ignored with an error beep. This prompt is supplied automatically by the ZKDU.
Edit Form Data - Once a Form has been activated, it will automatically indicate the last
information keyed in. If you want to retain that information, press ENTER .

The Auxiliary Port
The Auxiliary port is capable of supporting a single wedge device (barcode scanner, weight
scale, 10-key pad, etc.). The key features are:
• Only receives input data for auxiliary device.
• It is only active during Form data entry operations.
• It is active in both EPL and ZPL Form data entry operations.
• Includes low current +5 volt DC to power wedge devices.
• The port is configured as a Data Terminal Equipment (DTE) port.
Auxiliary Port Communication Configuration
Auxiliary port communication settings:
• Baud Rate: 4800
• Parity: none
• Data bits: 8
• Stop bits: 1
• Flow control: Hardware
• Data flow: Input only
ZKDU Pinout Configuration
The Auxiliary port connector is a Female DB-9. Low current +5 volt DC is supplied on pin 9
of the auxiliary port to retain backward compatibility to the KDU classic.
The + 5 Volt DC power supplied to the ZKDU via the printer, draws 50 mA for the ZKDU.
The remaining current is available to power peripheral devices attached to the ZKDU via the
Auxiliary Port. The current available depends upon the Zebra label printer type attached to the
port.
• Printers with ZPL allow 750 mA - 50 mA (ZKDU draw) = 700mA
• EPL only printer allow 250 mA - 50 mA (ZKDU draw) = 200mA
