unit power cord must be plugged into a grounded 3 - wire polarized AC wall socket. All normal
wiring and grounding precautions should be observed, including use of a "clean" AC power
line.

SCALE WIRING:The unit is equipped with cable gland entry for load cell cable insertion and
internal (pluggable) terminal strip for 4 / 6 wire connection. Remove sense jumpers P11-8/7,
P11-6/5 for six wire.

SETUP ACCESS

To access instrument configuration, calibration or to enable options, depress the “Zero” key for
five seconds.

The Audit Trail counters (“Pxxxx” and “Cxxxx”) are displayed first followed by access code
request (“AC?”). The initial factory setting is “0000” which can be entered with four steps of the
“0” key (“AC0000”) and “ENT”. If no entry is made, instrument returns to operate mode.

The access code can be changed to any four digit combination during setup exit when display
again shows “AC?”.

The “Check” key provides the software version “V 1.XX” followed by the display test routine.
Use the “ENT” key to advance to the keyboard test and to exit tests.

After entry, use the “Tare Recall” key to select a main menu; configuration (“SEL.CFG”),
calibration (“SEL.CAL”), or options (“SEL.OPX”) and “Start/Stop” to back step.

The “Gross/Net” key enters selected menu and is used to step through sub categories.
Individual parameter selection is made with the “Tare/Recall” key, which then steps through
the parameter choices (“Zero” key back steps within the menu).

The “ENT” key is used at any point to “back” up from categories to menus and to “save?” and
“AC?” and exit.

During the exit steps, if changes were made, the display is “save?” with alternate “no”. To save
changes, use the “Units” key to select “yes” and “ENT” to exit.
Calibration numeric entries are entered directly followed with the “ENT” key.

Front panel access is inhibited if conventional “sealing” is applied by
setting jumper J1-1 in the B position. The board mounted “CAL” button is
then used for access.

Remote Serial Display (RSD) Option

In RSD mode the instrument can be set to work with another unit as a “remote” either as the
main or the slave unit. Communication is pre-set for channel two only on both units.
(RS232, 9600, 8, none)

When in remote mode, re-access to the following selections requires using the internal “cal”
switch.

Remote unit can have full or partial control of the main unit. Devices are available to replace
the cable for wireless communication.

CALIBRATION: “SEL.CAL” Use Gross/Net to enter the menu indicated by a flashing “C” on
the left and live weight is displayed. Scale zero (dead load) or adjusting span (single or multi­point) are independent. Therefore either can be done and repeated as necessary before
exciting calibration. If an error has been made, exit without “storing” will return to prior setup.

KEY (FUNCTION) DISPLAY Definition

(Live weight 123 lb) “C”__123 Cal mode scale reading

Zero (acquire dead load) “------“ to “C___0.0” acquires new dead load

(Live weight 5000 lb) “C”__4995 Scale reading with load

Enter numeric value directly:

(Adjustment complete) 005000 adjusted value

Then ENT:

(Adjust span) “------“ to “C” 5000 displays new span

Repeat as required then ENT to exit CAL

“Save ?” “No” or “Save ?” “Yes” use Units to select and ENT to store “yes” with changes or
“no” to exit without changes.

Continue with ENT to “Ent AC” which allows access code change by entering a new four digit
code and ENT or ENT with no entry to maintain current password.

Option 5 Ten point calibration: Allows up to 10 span points (pt1…….pt10). Zeroing the scale
clears the existing values. Points are assigned incrementally with error indication if the addition
is not above the prior point or exceeding scale capacity.
Filter selection included for rolling or box averaging.

used to print the total, the “Ent” key returns to weigh mode.

The “Clear” key is used to clear the totalizer by first changing the message from
“Clr.ACC…no” to “Clr.ACC…yes” with the “Units” key and “Ent” to complete. A

Identification. Operates in “Gross” only.

This mode provides a system for single scale applications to determine net weight by
storing incoming weight and completing the transaction with out going weight.
Options are provided to maintain “store” Tares or to manually input tare weight.

Select ID: With “ID” displayed, user can select a stored ID by pressing “Set”

(up) or “Start/Stop” (down) to scroll through the buffer.

Print Buffer: Pushing Gross/Net with ID displayed will cause output of the

complete buffer ( ID with Tare).

Clear ID: Pushing clear with ID displayed will clear that ID and step to the

next.

Clear ALL: With “ID”, holding the clear switch will prompt “Rec.Clr” and using

unit to switch to “yes” and enter will clear entire buffer.

Option 7: SMART SERIAL I/O

The SMART SERIAL I/O option now offers a wide degree of flexibility for an operator to
customize the serial output format for individual system requirements. The custom print
currently supports:

 Specifying starting and terminating characters (stx, cr, lf, etc.).
 Adding printer control characters.
 Custom headers, titles, etc..
 Customized parameters such as "GROSS WEIGHT" instead of "GR".
 Custom insertion of special parameters such as time/date and identification no.
 Truck mode custom printing.
 Custom continuous serial protocol.
 Custom 'P' print out in duplex mode.

FEATURES:

* Eight (8) custom print files automatically assigned.

* Eight (8) macro files for easy setup of headers, titles, etc. .

* Capability to upload and download the custom print files to a host computer.

* Maximum file length is 30 characters and/or parameters. Maximum number of

characters in an output string is (250).

Note! Custom print does not support RS485 protocol

STANDARD SERIAL CONFIGURATION:

The SMART SERIAL I/O Option allows standard serial output ports to be modified and
imported into the serial output data stream.

The table below lists configuration parameters and Option modes that are associated
with the customized print.
CUSTOM PROTOCOL FILE SELECTION:
The selection of the associated custom print file is performed automatically by serial port
and the data mode (GROSS, NET, TOTAL RECALL, or SPECIAL) that the instrument is
currently in at the time of a print. In other words, if Ports 1 & 2 were selected for demand
print (dE) and the instrument was in the "GROSS" mode at the time of a print request of the
data, the serial output for Port 1 would use the contents of file 1 (7.1) and the contents of
file 5 (7.5) for Port 2.

23

GENERAL:
The selections under Option 7 may be divided into three main functional groups; the first 8
files (7.1 to 7.8), each of which can store up to 30 ASCII and/or parameter codes, are files
pertaining to the actual customization of serial output data and are themselves further
subdivided into Port 1 files (7.1 to 7.4) and Port 2 files (7.5 to 7.8), the second functional
group pertains to the 8 MACRO files (7.9 to 7.16) that may be entered into the primary files
(7.1 to 7.8) by their associated parameter codes 600 to 607 (7.9 = parameter code 600
etc.), each of these files can also store up to 30 ASCII and/or parameter codes.

Notes:

If Option 7 is enabled ("on") but a designated file is set to off then that print mode will print
its default format (eg. file 7.1 off - the GROSS data from Port 1 is sent out in its default
format).

24

MACRO FILES (7.9 TO 7.16):

There are eight (8) macro files that can be accessed in any of the prime Print Files 1 - 8
(7.1 to 7.8) using the "600" series codes. Each macro file holds up to 30 ASCII characters
and/or parameter codes.

Example: A header stating the company's name Scrap inc. is desired when Port 1 outputs
GROSS mode weight data.

Printout = Scrap inc.

CUSTOM PRINT FILES REMOTE READ AND WRITE

SSC (Smart Serial Codes) command is provided to read or write buffer data 7.1…7.16.

Example:

Read

SSC<CR>

SSC 1 2 600 200 32 601 13 10 999
SSC 9 83 99 114 97 112 32 105 110 99 46 13 10 999
SSC 10 402 32 401 999

Write

SSC<sp><X><yyy><yyy><cr> Where X = buffer 1…16 (7.1…7.16), yyy = code

With a txt editor (such as Windows Notepad) and the serial loader program, buffers can
be created and edited.

Text strings can also be entered directly surrounded by quotes:

SSC 9 “Scrap inc.” 702 999

Note: the 702 command CR/LF (13 10).
