Rice Lake 880 Performance Series Indicator/Controller Technical/Service Manual - Manual (Page 71)

EDP Commands 65
6.0 EDP Commands
The 880 indicator can be controlled by a personal computer or terminal connected to the EDP commands which
can simulate front panel key press functions, display and change setup parameters, and perform reporting
functions.
6.1 The EDP Command Set
The EDP command set can be divided into seven groups: key press commands, reporting commands, the
RESETCONFIGURATION
special function command, parameter setting commands, normal mode commands, error
conditions and batching control 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.
6.1.1 Key Press Commands
Key press EDP commands (see Table 6-1) 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
.
