.
1.0 Introduction
The F-Series flip digit remote displays provide
high-visibility, six-digit display capability for use in a
wide variety of applications. This manual provides
installation and configuration instructions for the F15
(1.5-inch), F40 (4-inch) and F60 (6-inch) flip digit
remote displays.
The F-Series remote displays are designed to work
with most digital weight indicators using 20 mA
current loop or RS-232 communications. The
AutoLink
™
learn mode function allows the F-Series
displays to automatically determine the data rate and
format sent by the attached indicator.
Optional features include time and temperature
display, fluorescent backlighting for increased display
visibility, and visor options for the F40 and F60
models.
Optional Features
Table 1-1 lists the optional features available for the
F-Series remote displays. Units can be ordered from
the factory with these options already installed, or the
options can be separately ordered and installed into
existing F-Series displays.

2 F-Series Remote Displays Installation Manual
2.0 Pre-Installation Setup
The F-Series remote displays should be set up,
configured, and tested before delivery to the
installation site.
This section describes RS-232 and 20 mA current
loop indicator connections. Once pre-installation
setup is complete, go to Section 3.0 for information
about configuring the remote display.
Use a wrist strap to ground yourself and
protect components from electrostatic
discharge (ESD) when handling chips
and working inside the remote display
enclosure.
2.1 Indicator Connections
To connect the communications cable to the remote
display, do the following:
1. Disconnect power and open the remote
display enclosure.
2. For Models F40 and F60, turn the retaining
screws and lower the hinged flip digit
mounting panel. For the Model F15, remove
the two screws from the hinged flip digit
mounting panel, then lower the panel.
3. Loosen the serial cable cord grip and push
only enough communications cable into the
enclosure to allow attachment at the terminal
block.
4. Strip 1/4 inch (.65 cm) of insulation from the
serial cable ends.
5. Make cable connections for RS-232 or 20 mA
current loop communications as described in
Sections 2.1.1 or 2.1.2, below.
6. For RS-232 connections, remove jumper
JMP1 on the CPU board (see Figure 2-1).
7. Remove any excess cable from inside the
enclosure, then tighten the serial cable cord
grip.
The DIP switches on the remote display CPU board
should be set and the remote display configuration
verified before sealing the display enclosure. DIP
switch configuration is described in Section 3.0.
A loop-back self-test can be used to test the function
of the remote display serial port. See Section 5.3 on
page 14 for information about the loop-back self-test.
2.1.1 RS-232
Figure 2-2 on page 3 shows the connections required
for RS-232 communications to the remote display.
See the manual for your indicator to determine the
indicator pin assignments for RS-232
communications.
2.1.2 20 mA Current Loop

4 F-Series Remote Displays Installation Manual
3.0 Configuration
The remote display and indicator should be
connected, configured, and tested before delivery to
the installation site. To begin configuration, ensure the
remote display is powered off and open the enclosure
to access the CPU board.
3.1 Indicator Configuration
When configuring the indicator attached to the remote
display, ensure that the decimal point configuration is
compatible with the remote display. Because the
F-Series remote displays use a fixed decimal point
between the third and fourth digits, weight data sent
from the indicator must be configured to show either
no decimal point (000000) or decimal thousandths
(000.000).
NOTE: The indicator must be configured to send
continuous (streaming) data to the remote display.
3.2 DIP Switch Configuration
The F-Series remote displays are configured using
four banks of eight DIP switches located along the
front edge of the CPU board. DIP switch settings are
read only when the remote display is powered on; to
change a switch setting, the unit must be powered off,
then on again, for the change to take effect.
The following sections include figures and tables
describing each of the DIP switch banks.
3.2.1 Serial Communications
DSW1 switches set the serial communications
configuration for the remote display.
Switch DSW1-1 allows data sent to the remote display
to be echoed back to the indicator or relayed to
another device, such as a printer or second remote
display.
The parity, data bits, and baud rate settings for the
remote display must match those configured for the
indicator unless learn mode (AutoLink) is used (see
Section 3.2.4 on page 5). If learn mode is enabled,
switches DSW1-4 through DSW1-8 are ignored.

3.2.2 Primary and Secondary Units
Switches DSW2-1 through DSW2-4 set the primary
and secondary annunciators for the remote display.
Using these switches, the lb and kg annunciators can
be assigned to designate pounds, kilograms, tons, or
metric tons (megagrams). Decals included with the
remote display can be used to change annunciator
labeling to show tons (T), metric tons (t), or
megagrams (Mg).
Actual function of the lb and kg annunciators depends
on the units information included in the indicator
serial stream.
Figure 3-1. DSW2 Switch Definitions
3.2.3 Display Type and Model
Switches DSW2-5 through DSW2-7 set the display
type and model. DSW2-7 must be off for all F-Series
remote displays.
3.2.4 Learn Mode (AutoLink)
The F-Series remote displays incorporate a software
feature called AutoLink . The AutoLink learn mode
function examines the serial data stream sent from the
attached indicator and attempts to determine the data
structure and format used by the indicator.
NOTE:
If learn mode is enabled, switches DSW1-4
through DSW1-8 and all DSW4 switch settings are
ignored.
Use the following procedure to learn the indicator
serial data stream:
1. Set DIP switch DSW2-8 on.
2. With wiring and configuration complete for
both the indicator and the remote display,
power on the indicator, then the remote
display.
3. When the power-up self-test is complete,
press the
LEARN MODE
switch on the
underside of the display enclosure. (See
page 10 for information about the self-test
procedure.)
4. The display shows the message
LOAd while it
examines the serial data stream sent from the
attached indicator. The LOAd message is
shifted off the display as the data stream
format is learned.
5. Next, the baud rate is shown in the format

.
6. Once the display determines the data format
being used, the message
LOAdEd
is shown.
If the display is unable to determine the data format
used, an error message is shown. See Section 5.1 on
page 12 for information about F-Series error
messages.
NOTES:
• The learned indicator data stream format stays
in the remote display memory even if the unit
is powered off. Press the
LEARN MODE
switch only to learn a new indicator format.
• Learn mode may be unable to read the serial
strings sent by some indicators or particular
indicator configurations. If learn mode is
unable to interpret the serial string, set switch
DSW2-8 off and use Table 3-5 on page 8 to
set DSW4 for the attached indicator.
3.2.5 Display Characteristics
Set switch DSW3-1 on to allow the remote display to
update weight data without waiting for scale
standstill.
Set switch DSW3-2 on to enable display of input error
messages. Section 5.1 on page 12 lists the F-Series
input and self-test error messages.
3.2.6 Time and Temperature Options
Switches DSW3-3 through DSW3-5 control the
display of time and temperature information for units
with these options installed. If these options are not
installed, set switches DSW3-3 and DSW3-5 off.

3.2.7 Suppress Leading Zeroes
Switch DSW3-6 enables suppression of leading
zeroes in weight values of less than 1. If DSW3-6 is
set on, weight values of less than 1 are shown with
only one zero to the left of the decimal point. For
example, a weight value received as 000.432 is shown
as 0.432.
If DSW3-6 is set off, the remote display shows the
zero format as sent by the indicator.
3.2.8 Loop-Back Self-Test
Switch DSW3-7 enables the loop-back self-test used
to check the remote display serial port. For normal
operation, set this switch off. See Section 5.3 on
page 14 for information about using the loop-back
self-test.
3.2.9 CPU Board Part Number
DSW3-8 specifies the part number of the CPU board
installed in the remote display. Some early production
units use CPU board PN 41033. The CPU board part
number is printed on the CPU board, slightly above
and to the right of DIP switch DSW4.
3.2.10 Indicator Type/Serial Format
Table 3-5 on page 8 shows the DSW4 switches used
to identify the serial format sent by the attached
indicator unless learn mode is used (see Section 3.2.4
on page 5). If learn mode is enabled, the DSW4
switch settings are ignored.
NOTE:
Learn mode may be unable to read the serial
strings sent by some indicators or particular indicator
configurations. If learn mode is unable to interpret the
serial string, set switch DSW2-8 off and use Table 3-5
to set DSW4 for the attached indicator.
3.3 Setting the Clock (for Units with the
Time Option Installed)
Once remote display configuration is complete and the
unit powered on, set the clock by doing the following:
1. Turn the clock switch to the
HRS SET
position
to set the hour. Hours digits count up once per
second while the switch is held in the
HRS
SET
position. Release the switch when the
current hour is displayed.
2. Turn the clock switch to the
MIN SET
position
to set the minute. Minutes digits count up
once per second while the switch is held in the
MIN SET
position. Release the switch when
the current minute is displayed.
The clock chip contains its own battery which
maintains the current time when the remote display is
powered off.
The current time is displayed when the weight reading
received by the remote display is zero. If the
temperature option is also installed and enabled, the
time and temperature displays alternate.

4.0 On-Site Installation
This section describes procedures for sealing the
enclosure and dimensions for mounting the F-Series
remote displays. Ensure that the remote display has
been tested and works with the indicator before
sealing and mounting the enclosure.
4.1 Sealing the Enclosure
Once pre-installation setup and configuration are
complete and the remote display has been tested with
the indicator, close and secure the enclosure cover.
For Model F15 remote displays, close the cover and
turn the screws to secure the enclosure.
For Models F40 and F60, securing the cover requires
15 (F40) or 17 (F60) bolts, all torqued to 20 in-lbs.
Use the torquing patterns shown in Figures 4-1 and
4-2 to prevent distorting the cover gasket.
NOTE:
When sealing the F40 and F60 enclosure
covers, you must make at least two passes through the
torquing pattern shown to ensure all bolts maintain the
20 in-lb. torque value.
Visor Option (Models F40 and F60)
To install the optional visor, place the rubber washers
over each of the 5 (F40) or 7 (F60) holes along the top
of the enclosure cover. Place the visor on top of the
washers, aligning the holes in the visor with those in
the enclosure cover. Insert the sealing washers and
bolts and torque to 20 in-lbs.

4.2 Mounting the Enclosure
Figures 4-3 through 4-5 show the enclosure
dimensions, mounting hole diameters, and distances
on center between mounting holes for each of the
F-Series models.
NOTE: The F-Series remote displays must be
mounted in a near-upright (90°) position to function
properly. Flip digit performance diminishes as the
mounting angle is increased (or decreased) from the
optimal 90°position. At too great an angle, the effect
of gravity on the flip digit mechanism causes the digits
and annunciators to stick.
4.3 Connecting Cables
Once the remote display is securely mounted, connect
the serial communications cable to the indicator as
described in the indicator manual. Last, connect the
remote display power cable to the AC power supply.
4.4 Remote Display Self-Test
When the remote display is powered on, the unit goes
through the following self-test procedure:
1. The remote display self-test checks the RAM
and EEPROM. If an error exists, the error is
shown at the end of the power-on sequence.
2. All flip digit segments are turned off, then on
(all 8’s displayed, decimal point and
annunciators set on), then off again. Watch the
display to determine whether any flip digit
segments or annunciators are stuck on or off.
3. If no errors are found, the remote display
shows the message PASS. If errors are found
during the RAM and EEPROM tests, the
display shows the message FAIL R (RAM
error) or FAIL E (bad EEPROM or bad data in
EEPROM).
If the loop-back self-test is enabled (DIP
switch 3-7 set on) and the test fails, the
message
FAIL S is shown, followed by one or
more of the messages listed above.
4. After showing the self-test status messages,
all segments are turned off once more, then
the software version number is shown.
See Section 5.0 on page 12 for more information
about error messages and the loop-back self-test.

14 F-Series Remote Displays Installation Manual
5.3 Loop-Back Self-Test
The F-Series remote displays provide a loop-back
self-test for use in diagnosing serial communications
errors. When enabled, the loop-back self-test runs as
part of the power-on self-test, checking the function of
the remote display serial port by sending and
receiving data to itself.
To perform the loop-back self-test, do the following:
1. Disconnect power to the remote display.
2. Open the remote display enclosure cover and
the flip digit mounting panel to access the
serial communications terminal block.
3. Disconnect any indicator wiring.
4. Connect jumpers to the terminal block as
shown in Figure 5-3. Wire the terminal block
only for the type of communications you are
using (RS-232 or 20 mA), not both.
Figure 5-3. Terminal Block Connections for Loop-Back
Self-Test
5. Set DIP switch DSW3-7 on to enable the
loop-back self-test.
6. Return the flip digit mounting panel to
operating position, close the cover, and set the
remote display upright.
7. Connect power to the remote display. The
loop-back self-test runs as part of the
power-on self-test:
• If all portions of the power-on self-test
are good, the message PASS is shown.
• If the loop-back self-test fails, the
message FAIL S is shown, followed by
one or more other messages. If the
loop-back self-test fails but all other
tests are good, the display will show the
message FAIL S, then PASS.
If the loop-back self-test fails, the serial port is not
functional. Be sure to check the following when
troubleshooting the serial port:
• For 20 mA communications, ensure that 20
mA chips are installed correctly and the
jumper at JMP1 is on. See Figure 2-1 on page
2 for component locations.
• For RS-232 communications, ensure that
jumper JMP1 is off.
• Check continuity of wires between connector
J3 on the CPU board and the serial
communications terminal block.
