9.0 Serial Commands
The 920i indicator can be controlled by a personal
computer or remote keyboard connected to an
indicator serial port. Control is provided by a set of
serial commands that can simulate front panel key
press functions, display and change setup parameters,
and perform reporting functions. The serial commands
provide the capability to print configuration data or to
save that data to an attached personal computer. This
section describes the serial command set and
procedures for saving and transferring data using the
serial ports.
9.1 The Serial Command Set
The serial 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 a serial 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
??
.
9.1.1 Key Press Commands
Key press serial 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
normal (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
serial commands:
1. Type K1 and press
ENTER
(or
RETURN
).
2. Type K5 and press
ENTER
.
3. Type KTARE and press
ENTER
.
