10.0 Serial Commands
The 720i 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
s e c t i o n d e s c r i b e s t h e s e r i a l c o m m a n d s e t a n d
procedures for saving and transferring data using the
serial ports.
10.1 The Serial Command Set
The serial 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 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
?? .
The following sections list the commands and
command syntax used for each of these groups.
10.1.1 Key Press Commands
Key press serial commands (see Table 10-1) 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 .
