5.0 EDP Commands
The
320IS
indicator can be controlled by a personal computer or remote keyboard connected to the I/O Module’s
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
RESETCONFIGURATION special function 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:
Scale must be at zero gross.
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.
