Q uick Setup Procedure
Placing weight on the scale can be advantageous in shifting
the weight into the correct position. Wire up the display
according to Section 2. C onfigure the transmitting device to
output continuously. Press and release the RE SE T button on
the display. While the display is counting down from 9 to 0
hold the LE A R N button. At the end of countdown the
display will flash a baud rate such as 1200, and then will
display the beginning of the data stream. Shift the stream
left using the LE F T button until the desired weight is in view.

The SBL Series has an echo feature which will take the
received data stream and echo it out to further displays via
RS 232, C urrent Loop or RS 422. (To transmit RS 422 remove
the 8 pin DS 75176 in socket U5 and place it in U8)
The echo feature transmits every other data stream unless
option 4 is enabled. See Section 5 for more details.

JUMP

The green LED will be illuminated when the following four
requirements are satisfied:
1. The display is powered on.
2. The indicator’ s port is enabled to transmit continuously.
3. The jumper is in the correct position.
4. The wires are connected to the terminal block as
described    previously.
The display will learn to the transmitting device when the
LE A R N button is pressed at the end of startup. It will display
the baud rate and then display the first six characters in the
data stream. Pressing the LE FT button will move the
displayed stream to the left until the desired data can be
seen on the Remote.

Changing Intensity
To change the display’ s intensity press and release the RE SE T
button then hold the RIG HT button during countdown. At the
end of countdown the R IG H T button will toggle between
displaying “ high” and “ low” (on 7 segment displays “ lo” is
displayed). Select the desired intensity and press LE A R N to
save changes. Factory default is “ low” .

O ption Summary
To enter into the options hold the LE F T button during power
up. At the end of the countdown the display will display
" O PTIO N " . O nce in options, LE F T will cycle through the
option numbers 0 through 20. The R IG H T button will toggle
between O n/O ff for some options and will enter into an
advanced menu for more complicated options. See specific
options in Section V for more advanced option descriptions.
Pressing LE A R N at any time will save the settings and reset
the display. Pressing both LE FT and R IG H T during power up
acts the same as O ption 0 and will restore the display to
factory defaults.

O ption Details continued
O ption 3 Timeout Length
O ption 3 is used to set the timeout length. The timeout length
is the maximum amount of time expected between data streams
before communication is considered interrupted. The default
(0/O ff) acts as a 5 second timeout, all other values represent the
number of seconds the display will wait for a new data stream.
The display will then do one of three things after the timeout
depending on how O ption 5 is set. The maximum timeout
allowed to be set is 255 seconds. While in setup for the time
out option LE FT decrements the value and R IG HT increments.
O ption 4 Display on Demand
O ption 4 sets the display for O n Demand mode. It is
recommended to be turned on when connected to the print
button of an indicator or when data is only sent once every 2
or more seconds. While in O n Demand mode the display will
wait for and display every data stream. While in the default
(off) the display uses every other data stream to ensure data
integrity.
O ption 5 N o Data
O ption 5 sets the display to do one of three things after a data
stream time out. The default is to display " NoData" . The other
two options are " Clear" (blank the display) and " Hold" (keep the
last weight sent). The time out length can be specified with
O ption 3. RIG H T toggles between the three choices, " N oData" ,
" Clear" , and " Hold" .

10
O ption Details continued
O ption 6 Fixed Decimal Point
O ption 6 will set the display to illuminate a decimal point when
it is not present in the data stream. Default (off) will show a
decimal point only where it is located in the data stream. All
other values represent the digit to attach a decimal point to,
starting from right to left.

O ption 7 N o C ount Down
O ption 7 will disable the display from counting down from 9 to
0 when powered up.
O ption 8 N o Zero Suppression
O ption 8 will disable the display’ s ability to suppress leading
" 0" s with spaces. The default (off) will display a space for all
leading " 0" s up to the final two in the 1s and 10s column or
up to a " 0" immediately in front of a decimal point. For
example when the option is off the stream " 000000" will become
" 00" and the stream " 0000.00" will become " 0.00" .
O ption 9 Display A lpha C haracters
O ption 9 will enable the unit to display both alpha and numeric
characters. The default (off) will replace all non-numerics with
spaces. A 7 segment display is limited by the alpha characters
it can display. For example it can not display characters such as
" x" , " q" , " k" , " !" or " ?" .

11
O ption Details continued
O ption 10 M irror
O ption 10 enables a display to be read in a rear view mirror.
The default (off) is for direct viewing.
O ption 11 A ddressable
O ption 11 will set the display to be addressable. The display
will ignore any characters until the addressable character is
received, then display the data immediately following it. The
addressable character can be set to any character from 1 to
255. The number selected represents the decimal equivalent of
the desired character. For example if an " A" is at the
beginning of the data stream then you would set the address to
65. LE F T decrements the character value and R IG H T increments
the character value. See Section VII for ASC II character values.
If the indicator is sending 7 data bits even or odd parity then
the parity bit may change the decimal value of the character by
adding 128 to it. We recommend setting the indicator to 8
data bits no parity for convenience. Default (off) uses standard
data stream
O ption 12 Time O ption
O ption 12 is only available with additional hardware purchase.
When purchased this option is used to set the clock on the
display. LE FT increments the hours and R IG H T increments the
minutes.
O ption 13 Fixed Shift Value
O ption 13 is used to set a fixed shift amount. Turning this
option on will prevent the display from resetting the shift value
when the display goes through the LE A R N process. It will also
disable the LE F T and R IG HT buttons from shifting the stream.
The shift value can be set to any amount between 1 and 255,
however due to data stream length limitations any number over

12
O ption Details continued
O ption 14 Fixed Baud Rate
O ption 14 disables the auto-learn's ability to detect the baud
rate of the data stream and instead configures the baud rate to
the set amount. Default (off) will allow the unit to learn on
power up when LE A R N is pressed for the correct baud rate.
RIG H T cycles through the baud rate possibilities of 300, 600,
1200, 2400, 4800, 9600, and 19200.
O ption 15 Fixed E nd C haracter
O ption 15 disables the auto-learn's ability to detect a data
stream's end character. It instead uses only a specific end
character. Default (off) will allow the unit to learn on power up
when LE A R N is pressed for the correct end character. Possible
end characters accepted in default mode include an end of
text(EO T), line feed(LF), and carriage return(C R), which have the
decimal values of 03, 10, and 13 respectively. Turning on the
fixed end character will set the end character into any
character. Set the display to the decimal equivalent of the
desired character. LE FT decrements the character value and
RIG H T increments the character value. Any character from 1 to
255 can be selected. See Section VII for ASC II character values.
If the indicator is sending 7 data bits even or odd parity then
the parity bit may change the decimal value of the character by
adding 128 to it. We recommend setting the indicator to 8
data bits no parity for convenience.
O ption 16 M inimum Weight
O ption 16 sets the minimum weight that the unit will display.
LE FT will change the value of the selected digit and R IG HT will
change which digit is selected. For example if you set the
minimum weight to " 000030" and the indicator is sending
" 000000" then the display will go B LA N K until the threshold
value is exceeded.

13
O ption Details continued
O ption 17 M aximum W eight
O ption 17 sets the maximum weight that the unit will display.
LE FT will change the value of the selected digit and R IG HT will
change which digit is selected. For example if you set the
maximum weight to " 100000" and the indicator is sending
" 120000" then the display will go B LA N K until the weight drops
below the threshold value.
O ption 18 Future O p
O ption 18 is reserved for a future option.
O ption 19 Test M ode
O ption 19 sets the display in test mode. While in test mode,
the display will cycle through several weights and output those
weights through the serial ports. Test mode can be used to
test the digits, test the unit’ s ability to output and to quickly
demonstrate the unit's appearance of different characters to an
end user.
O ption 20 Version
O ption 20 displays the software version of the display. The unit
will display the month, followed by the year. This option is only
used for trouble shooting purposes.
