420 Plus Installation Manual - EDP Commands 33
5.0 EDP Commands
The
420 Plus
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 can be divided into five groups:
key press commands, reporting commands, the
R E S E T C O N F I G U R AT I O N s p e c i a l f u n c t i o n
command, parameter setting commands, and transmit
weight data commands.
When the indicator processes an EDP command, it
responds with the message
OK
. The
OK
response
verifies that the command was received and has been
executed. 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 keys on the front panel of the indicator.
Most commands can be used in both setup and
weighing mode. Several of the commands serve as
“pseudo” keys, providing functions that are not
represented by a key on the front panel.
For example, to enter a 15-pound tare weight using
EDP commands:
1. Type K1 and press
ENTER
(or
RETURN
).
2. Type K5 and press
ENTER
.
3. Type KTARE and press
ENTER
. The display
shifts to net mode when the tare is entered.
