EDP Commands 50
9.0 EDP Commands
The 520 indicator can be controlled by a personal
computer or terminal 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.
9.1 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.
9.1.1 Key Press Commands
Key press EDP commands (see Table 9-1) simulate
pressing the keys on the front panel of the indicator.
These 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
.
