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,

transferring data using the serial ports.
9.1 The Serial Command Set
The serial command set can be divided into Þve
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
veriÞes 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.
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 ÒpseudoÓ 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 .
