48 CW-90/90X Checkweigher
6.0 Serial Commands
The CW-90/CW-90X can be controlled by a PC 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
f u n c t i o n s . T h i s p r o v i d e s t h e a b i l i t y t o p r i n t
configuration data or to save to your hard drive.
6.1 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 a serial command is
processed, the CW-90/CW-90X responds with the
message
O K . The O K response verifies that the
command was received and has been executed. If the
command is unrecognized or cannot be executed, the
CW-90/CW-90X 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 serial 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 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:
1. Type K1 and press ENTER (or RETURN ).
2. Type K5 and press ENTER .
3. Type KTARE and press ENTER .
