26 Tracer AV Installation Manual
5.0 EDP Commands
The Tracer AV can be controlled by a personal
computer or remote keyboard connected to the 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 Tracer AV 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 2-button keypad. 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
2. Type K5 and press
ENTER
3. Type KTARE and press
ENTER
The display shifts to net mode when the tare is
entered.
