Rice Lake 120 Digital Weight Indicator - Manual (Page 27)

EDP Commands 23
5.0 EDP Commands
The 120 indicator can be controlled by a personal
computer or remote keyboard connected to the
indicator EDP port. Control is provided by a set of
EDP commands that can simulate front panel key
press functions, display and change setup parameters,
and perform reporting functions. The EDP port
provides the capability to print configuration data or
to save that data to an attached personal computer.
This section describes the EDP command set and
procedures for saving and transferring data using the
EDP port.
5.1 The EDP Command Set
The EDP command set includes key press commands,
mode commands, reporting commands, the RS special
function command, and parameter setting commands.
The indicator responds to most EDP commands by
sending the message
OK . The OK response verifies that
the command was received and has been executed.
(Pressing
E NT ER after processing a valid EDP
command repeats the previous command.) If the
command is unrecognized or cannot be executed, the
indicator responds with
?? .
The following sections list the commands and
command syntax used for each of these groups.
5.1.1 Key Press Commands
Key press EDP commands (see Table 5-1) simulate
pressing the front panel indicator keys. These
commands can be used in both configuration and
weighing mode.
Table 5-1. Key Press EDP Commands
Command Function
KZERO In weighing mode, press the ZERO key
KGROSSNET In weighing mode, press the GROSS/
NET key
KTARE In weighing mode, press the TARE key
KUNITS In weighing mode, press the UNITS key
KPRINT In weighing mode, press the PRINT key
5.1.2 Reporting Commands
Reporting commands (Table 5-2) send specific
information to the EDP port. These commands can be
used in both configuration mode and normal mode.

Command Function
DUMPALL List all parameter values
VERSION Write 120 software version
P Write current displayed weight with units
identifier
RS Reset software
5.1.3 The RS Command
The RS (reset configuration) command can be used to
restore all configuration parameters to their default
values. Before issuing this command, the indicator
must be placed in test mode (press and hold setup
switch for approximately three seconds to enter test
mode).
This command is equivalent to using the DEFLT
function on the TEST menu. See Section 7.7 on
page 35 for more information about test mode and
using the TEST menu.
Note
All load cell calibration settings are lost when
the RS command is run.
5.1.4Parameter Setting Commands
Parameter setting commands allow you to display or
change the current value for a particular configuration
parameter (Tables 5-3 through 5-8).
Current configuration parameter settings can be
displayed in either configuration mode or normal
mode using the following syntax:
command<ENTER>
M o s t p a r a m e t e r v a l u e s c a n b e c h a n g e d i n
configuration mode only. Use the following command
syntax when changing parameter values:
command=value<ENTER>
where value is a number or a parameter value. Use no
spaces before or after the equal (=) sign. If you type an
incorrect command or value, the display reads
?? .
Changes to the parameters are saved as they are
entered but typically do not take effect until you exit
configuration mode.
For example, to set the motion band parameter to 5,
type the following:
MOTBAND=5D<ENTER>
