Introduction
This manual provides detailed information for operating the LYNX terminal, a high
performance industrial scale terminal that combines flexibility and speed with an easyto-use operator interface to meet a wide range of weighing needs quickly and reliably.
Information on installing, programming, and servicing the LYNX terminal can be found
in the LYNX Terminal Technical Manual.
Review all instructions and safety precautions carefully. Only authorized personnel
should perform installation and service procedures.
If you encounter problems not covered in this manual, please contact your authorized
METTLER TOLEDO representative.
Cleaning and Regular
Maintenance
In almost all cases, as an operator, you will not need to be concerned about installing
or servicing the LYNX terminal. However, you may be required to clean the terminal and
provide regular maintenance. You may wipe the keyboard and covers with a clean, soft
cloth that has been dampened with a mild glass cleaner. Do not use any type of
industrial solvent such as toluene or isopropanol (IPA) as they may damage the
terminal's finish. Do not spray cleaner directly on the terminal.
Regular maintenance inspections and calibration by a qualified service technician are
recommended.

LYNX Terminal Features and Operations
LYNX Display Area
The LYNX terminal has a single alphanumeric display where scale data and operational
messages are presented. The display is pictured below:
R1
R2
Figure 2-1 LYNX Display and Keypad
The 10-character alphanumeric display can display letters and/or numbers. Each
character also has a comma and decimal point associated with it. The display indicates
scale weight unless you are in setup mode (used for programming the LYNX terminal)
or using prompting.
Annunciators point to labels in the legend directly below the display area. The
annunciators indicate:
• Weighing mode (Gross or NET)
The LYNX terminal is in net mode (NET) when a tare is active. A tare can be entered
as a Preset Tare value or automatically acquired when you press the TARE key. Tare
can also be entered through an interface. If no tare is active the LYNX terminal will be
in gross mode (G).
• Type of tare (Preset Tare or Tare)
The preset tare (PT) annunciator indicates a preset tare has been recalled and
displayed. Preset tare is entered manually using the numeric keys on the keypad.
Preset tare is also referred to as keyboard tare or manual tare.
The Tare (T) annunciator indicates that a pushbutton tare or automatic tare has been
recalled and displayed. You can perform a pushbutton tare by pressing TARE. If Auto
Tare was enabled in setup, tare can be taken automatically when a container is
placed on the scale.
• Center-of-zero (→
→0←
←)
The center-of-zero annunciator indicates that the scale is within ± 1/4 increment of
gross zero.
(6/01) 2-3
METTLER TOLEDO LYNX Terminal User’s Guide
• Scale instability (~)
The scale instability annunciator indicates that the scale is in motion. The annunciator
will turn off when the scale is stable. The sensitivity of motion detection can be
adjusted in setup.
• Discrete Outputs 1–2
The discrete output annunciator indicates that the associated discrete output on the
LYNX Controller PCB is on. The LYNX terminal only displays the status of outputs 1
and 2. The status of output 3,4, and 5 is not available on the display. Output
functions are programmed in setup.
• Weighing Range R1 or R2
If the LYNX terminal is configured for two weighing ranges, the R1 annunciator will
indicate that the scale is in the low range and R2 the high range.
LYNX Terminal Keypad
The LYNX terminal features a 20-key keypad as shown here:
Figure 2-2 LYNX Keypad
The keypad consists of numeric keys 0 through 9, a decimal point, a space key, and
eight function keys. The numeric keys also contain alphabet characters and special
symbols.
The keys perform the following functions:
• NUMERIC Keys are used to input numbers and the alphabet characters and symbols
that appear on the specific keys. (See Alphabetical and Special Character Entry later
in this chapter.)
• DECIMAL POINT (.) inserts a decimal point as necessary. It is also used to enter the
symbols "−", "/", and "=".
• SPACE (SP) inserts a space where necessary. It is also used to enter the symbols
"*", "(", and ")".

the gross weight value to be recalled on the weight display.
Accumulation Recall and Print—If enabled, accumulation recall and print lets you
recall and print accumulated totals.
ID/Tare View and Print—If enabled, ID/Tare view and recall and print lets you view
and print a single stored tare record or reports showing multiple records.
Enter Setup—If configured, you may use the FUNCTION and SELECT keys to enter
setup and configure the program blocks in setup mode.
Edit
When editing a text string, the FUNCTION key acts as a right arrow moving
the cursor one position to the right with each keystroke.
• MEMORY (M) accesses various memory functions depending on the LYNX terminal's
setup configuration including:
Recall ID—If ID/Tare is enabled, recall ID lets you recall a stored ID record from
memory.
Store ID—If ID/Tare is enabled, store ID lets you store a weight transaction in
memory.
Prompt List—Prompt lists permit data entry into a user-defined prompt list which
was created through the Configure Memory program block in setup.
Setpoints—If accessed, this feature lets you enter setpoint cutoff values.
Consecutive Number—This feature displays the current consecutive number. You
can also reset the consecutive number.
Time—The time feature displays the clock and allows adjustment of the time.
Date—The date feature displays the date and allows adjustment of the date.
Edit
When editing a text string, the MEMORY key acts as a left arrow moving the
cursor one position to the left with each keystroke.
• SELECT (S) scrolls through and displays items in option lists and acts as a special
function key if assigned in the Application Environment program block.
• ZERO (→0←) zeroes the scale.
• ESCAPE (ESC) exits an operating mode.
• TARE (T) performs a pushbutton tare function if enabled in setup.
• CLEAR (C) clears a tare value and returns the scale to gross mode. The CLEAR key
also functions as a backspace/delete when entering data from the keypad.
• ENTER acknowledges a prompt and accepts data entered from the keypad. ENTER
also initiates a demand print output.

Power-up Sequence
The LYNX terminal goes through a series of self-tests when it is turned on. These tests
confirm normal terminal operation. The power-up sequence is as follows:
1. All segments of the display window are lit. This verifies operation of all segments.
2. The LYNX terminal performs internal power-up tests and displays the following
messages as these tests are performed:
METTLER
TOLEDO
**LYNX**
3. After a delay, the terminal displays the software part number.
4. Next, the terminal tests communication with the load cell. The terminal displays
weight when successful communication is established. If the LYNX terminal is
unable to establish communication, an error is displayed.
5. Finally, if enabled, the LYNX terminal’s power-up timer counts the minutes and
seconds remaining before the unit advances to normal operating mode. Power-up
timer configuration is discussed in the LYNX Terminal Technical Manual.
The total power up sequence requires approximately 25 seconds. This delay is
analogous to the time required to "boot" a personal computer.

Tare operations are enabled or disabled in setup.
Pushbutton Tare
Pushbutton tare compensates for weight (usually an unknown quantity such as an
empty box or other container) on the weighing platform with a single keystroke and
switches the terminal to net mode.
If Pushbutton Tare is Enabled:
1. Place a load to be tared on the scale platform and press the TARE key on the
keyboard. The display area reads 0.0 with the net annunciator illuminated.
2. Place the load to be weighed on the platform. The net weight of the load is
displayed.
3. Clear tare by pressing CLEAR. The terminal returns to gross mode and displays the
weight on the platform.

(6/01)
Chapter 3: Operating Instructions
Tare Operations
Example: Pushbutton Tare
The operator places an empty container on the scale and the display shows 12.3 lb
with the Gross annunciator lit. The operator presses TARE and the display shows 0.0
lb with the NET annunciator lit. The operator then fills the container with 50 pounds
of material. The terminal displays the net weight of the load in the container as 50.0
lb with the NET annunciator lit.
When the filled container is removed, the display shows the negative tare value as
−12.3 lb with the NET annunciator lit. The operator presses CLEAR and the LYNX
returns to gross zero.
Preset (Keyboard) Tare
Preset tare, sometimes called keyboard tare, compensates for a known tare weight on
the scale. Preset tare is used when the net weight of contents in a filled container must
be determined and the tare weight is known.
If Preset (KB) Tare is Enabled:
1. Place the load on the platform. The display shows the gross weight of the load. Be
sure you know the weight of the portion to be compensated for by preset tare.
2. Use the numeric keys to enter the known tare weight. Then press ENTER. The net
weight of the load is with an annunciator indicating NET.
3. Clear tare by pressing CLEAR. The terminal returns to gross mode and displays the
gross weight on the platform.
Example: Preset Tare Enabled
A loaded truck (80,000 pounds) is driven onto a weigh station platform and the
operator enters the known weight of the truck (17,500 pounds). The LYNX terminal
displays the net weight of the truck's contents as 62,500 lb with the NET
annunciator lit.
When the truck is driven off the platform, the operator presses CLEAR to clear the
tare value and return the terminal to gross zero.
Auto Tare
Auto tare automatically tares the indicator when a stable load on the platform exceeds a
preset gross weight threshold value. A gross weight reset value is also used to determine
when the terminal will be "re-armed" to do another auto tare.
If enabled, the LYNX terminal checks the stability of the load before rearming auto tare.
You may want to disable motion check if the load will not become stable, as when
rapidly weighing one item after another.
If Auto Tare is Enabled:
The operator does not have to press any key to perform tare if Auto Tare is enabled, but
must press CLEAR to return to gross mode.
1. Place a load on the scale platform that exceeds the tare threshold value. When the
scale is stable, the terminal automatically tares the scale to net zero.
2. Place the load to be weighed on the platform. The LYNX terminal displays the net
weight with an annunciator indicating NET.
3. Clear tare and return to gross mode by pressing the CLEAR key.
4. When the weight is removed and the reset threshold is passed, the scale rearms for
the next sequence.
(4/01) 3-3
METTLER TOLEDO LYNX Terminal User’s Guide
Example: Auto Tare Enabled
The auto tare threshold value has been set to 100 pounds through the Application
Environment program block. The operator places an empty container on the
platform that weighs more than 100 pounds. The LYNX terminal automatically tares
the scale and displays 0 lb NET. The operator then fills the container and records
the net weight of the load.
When the filled container is removed and the weight on the platform falls below the
reset threshold value, the LYNX terminal rearms and is ready for the next container.
If check motion is enabled, the LYNX terminal will not rearm unless the weight on
the scale settles below the reset threshold value.
Auto Clear Tare
Auto clear tare can be used in conjunction with any or all of the tare options described
above. This feature automatically clears the tare and returns the terminal to gross mode
when weight on the platform has exceeded, then fallen below a preset gross weight
threshold value.
The check motion parameter can be enabled to ensure the scale weight is stable before
automatically clearing tare.
Recall Tare
The LYNX terminal allows you to recall and display the tare while in net mode. Tare
recall is accessed by using the FUNCTION key.
Recall Gross
The LYNX terminal allows you to recall and display the gross weight while in net mode.
This may be useful if you need to see the gross weight but do not wish to clear the
current tare value. Gross weight recall is accessed through the FUNCTION key.
Tare Interlock
Tare interlock imposes some restrictions on tare operations. If tare interlock is enabled,
tare may be cleared only at gross zero, and multiple tares are prohibited.
Print Operations
The LYNX terminal supports the following print operations:
•
•
•
•
•
•
Demand Print
Minimum Print
Print Interlock
Auto Print
Net Sign Correction
Continuous Output
Any or all of the print operations can be enabled or disabled in setup. The print output
format and destination port are also determined in setup. Output can be directed through
one or more local serial ports (COM1, COM2, or COM3).
Demand Print
If a demand mode connection is configured, demand printing is initiated when an
operator presses the ENTER key in normal operating mode or through an external
interface such as a discrete input port or an ASCII input command. If no conditions exist
3-4
(6/01)
Chapter 3: Operating Instructions
Automatic Prompting Operations
to inhibit printing, output will be sent to the connected printer and the terminal displays
the message PRINTING.
If a demand mode connection is not configured, the terminal displays PRINT INHIBITED.
If a demand print is requested while weight on the scale is unstable, the LYNX terminal
waits until motion stops, then prints.
If no demand mode connection is selected but a host or continuous connection exists,
the display reads PRINT REQUESTED and the respective connections reflect the request.
Minimum Print
The minimum print parameter prohibits data output if gross weight on the scale is below
a threshold value configured in setup. If you press ENTER to initiate printing with scale
weight below the threshold value, the terminal displays PRINT NOT READY on the
display.
Print Interlock
Print interlock prevents multiple print requests for a single weighing transaction. Print
threshold and reset values determine operation of print interlock. Additionally, a check
motion before reset parameter can be enabled.
If print interlock is enabled and conditions of print interlock are not satisfied, the terminal
displays PRINT NOT READY.
Auto Print
Auto print allows printing to occur without operator action. The terminal automatically
initiates data output when gross weight on the scale settles above the print threshold
value. Auto print is “re-armed” when the weight falls below the reset threshold value. A
check motion before reset parameter can also be configured for auto print.
Continuous Output
Serial ports can be configured to output data continuously. In continuous mode, weight
data is transmitted up to 20 times per second in a fixed format. A status bit in the fixed
format changes state when a demand print request is received.
Host Mode
Serial ports can also be configured for connections to a host device such as a personal
computer. In the host mode, weight data can only be requested from the host device;
data is not transmitted without a request. A status bit in one of the host status bytes
indicates a print request has been received.
Automatic Prompting
Operations
Automatic prompting causes the LYNX terminal to automatically jump from the normal
weighing mode to the first step in a prompt list. Prompt lists, described later in this
chapter, facilitate specific data input from the operator or cause some specific action to
take place, such as taring the scale or printing.
If automatic prompting is enabled, the LYNX terminal will jump to the prompt list
whenever the weight exceeds a preset, auto prompt threshold value. It will then be “rearmed” for the next cycle when the weight drops below the auto prompt value. Whether
or not the scale must settle to a no-motion state before jumping or re-arming is
determined by setting a flag in the auto prompt setup program sub-block.

The LYNX terminal can store up to 99
commonly used tare values in
memory.
Store and Recall Temporary and Permanent ID/Tare Records
The LYNX terminal can store two types of tare records in memory: temporary and
permanent tares. Temporary tare records are stored and recalled with the MEMORY key
and are automatically cleared after recall. Temporary tare records are used for one
transaction only.
Permanent tare records are also stored and recalled with the MEMORY key; however,
permanent tare records can be used repeatedly as defined in setup.
Each tare record can be accessed with a one- or two-digit ID number or an
alphanumeric Record ID (up to 10 characters).
Example: The following illustrates temporary vs. permanent tare records.
A privately contracted truck comes onto a scale at a filling site. It will fill only one
load for the contractor. Because this truck will be weighed in and out only once, the
operator enters the truck’s tare weight as a temporary record.
You may also be able to use the auto
print feature depending on setup
configuration.
The truck is filled and comes back onto the scale to be weighed out. The operator
recalls the previously stored temporary tare record. The LYNX terminal prints a ticket
and displays net weight. The temporary tare record is automatically cleared and
cannot be recalled again.
If auto print is enabled in setup, LYNX
prints the transaction then displays
net weight.
However, if one or several trucks are filled and weighed repeatedly, the operator
would enter the trucks’ tare weights as permanent records. Each time the filled truck
comes onto the scale, the operator would recall the permanent ID/Tare record. The
LYNX terminal would print a ticket and display net weight. The permanent tare
record can be recalled as many times as configured in setup.
The FUNCTION key lets you generate reports listing data pertaining to temporary and
permanent ID/Tare records. You can also clear ID/Tare records. Please refer to the
following section entitled Function Key Operations for more information.
The Descript? prompt appears
only if enabled in setup.
Tare and net weight printing
operations are possible when
recalling a stored tare value.
To store a temporary ID/Tare record:
In normal operating mode and with the container to be tared on the platform, press
MEMORY, then press SELECT to display the Store ID? prompt. Press ENTER.
1. At the ID? prompt, enter an ID designation. If one or two digits are entered, the ID is
stored as a numeric ID number. If more than two digits are entered, or if
alphanumeric characters are entered, the ID is stored as a Record ID.
2. The LYNX terminal automatically searches its memory to verify that the entered ID
designation is not already used. If the record ID is not already used, the LYNX

(6/01)
The LYNX terminal's prompt list feature is a simple but powerful means of facilitating
specific data input from the operator or to cause a specific action to take place. The
prompt list may be up to 20 steps with each step containing a command that
determines the action the LYNX terminal will take when the step in executed.
Chapter 3: Operating Instructions
MEMORY Key
Operations
The prompt list can be accessed automatically when a weight threshold is exceed, if
auto prompting is enabled, by assigning the prompt list to the action of the SELECT key
or by using the MEMORY key as follows:
In the normal weighing mode, press the MEMORY key then press SELECT to display
Prompt List? Press ENTER.
METTLER TOLEDO recommends
disabling unit switching to avoid
confusion when using setpoints.
If password protection is not enabled,
continue to step 3.
The LYNX terminal prompts only for
the selected setpoint fields during
setpoint programming. If preact is not
enabled in setup, LYNX will not
prompt for preact.
Respond to each prompt, if appropriate, as indicated by the prompt. Some prompts,
such as an automatic tare or print command, do not require a response. If manual data
entry is required, you must press ENTER to terminate the input.
After the final prompt, the LYNX terminal will return to the normal weighing mode unless
“loop mode” was selected in setup. Loop mode will cause the LYNX terminal to start
over again at the first prompt. You may press ESC at any time in the prompt list
sequence to terminate prompt list execution.
Assign Setpoints
The LYNX terminal can control up to five single-speed setpoints or a combination of
single-speed and two-speed setpoints. These outputs are available on the PAR2
connector of the Controller PCB and in the continuous output of the LYNX terminal.
Single-speed setpoints consist of a coincidence setpoint value and a preact value (if
enabled in setup). The preact value compensates for material in suspension that will still
fall onto the scale after the setpoint is turned off. The setpoint actually turns off at the
programmed setpoint minus the preact value.
Two-speed setpoints consist of a setpoint value, a dribble value, and a preact value.
Tolerance is also programmable. With two-speed setpoints, the dribble value can be
programmed to define an amount of material to be fed at a slower rate. The slower
delivery rate begins when weight on the scale equals the setpoint value minus the
dribble value.
The LYNX terminal prompts for setpoint and tolerance values if these features are
enabled in setup. You can also select in setup which weight will be used with the
setpoints (gross, net, or displayed).
To enter setpoint values:
1. Press MEMORY. Then press SELECT until the prompt Setpoints? is displayed. Then
press ENTER to access setpoints.
2. If password protection is enabled in setup, at the Pass? prompt, enter a valid
password. (If you enter an invalid password, the LYNX terminal responds INVALID
PASSWORD and returns to normal operating mode.)
3. At the Setpt#? 1 prompt, press ENTER to access setpoint 1, or press SELECT to
access another setpoint, followed by ENTER.
If the selected setpoint is a single-speed setpoint:
• At the Setpoint? prompt, press SELECT to accept the current setpoint value and
continue. Alternately, you can press ENTER if you wish to view or change the
actual setpoint value, then use the numeric keys to enter a new setpoint value.
• At the Preact? prompt, press SELECT to accept the current preact value and
continue. Or, you can press ENTER to access and view or change the preact
value, then use the numeric keys to enter a new preact value.
