Appendix 3: ASCII Input
Commands
Beginning with software version 2.00, the WILDCAT scale has the ability to receive
certain ASCII characters via the serial port to perform simple keyboard functions.
Previous versions of software did not have this capability. The software version can be
viewed at power up.
The ASCII input commands will operate when the serial port is programmed for either
demand output or continuous output. The input character format must be the same as
the data output format selected in setup including baud rate, data bits, parity and stop
bits. The remote commands are subject to the same restrictions as the keyboard
equivalents. For instance, tare, zero and print commands will only operate if sent when
there is no motion on the scale. When sending multiple commands, there must be a
time delay of at least one-half second (500 milliseconds) between each remote ASCII
command character.
These ASCII commands duplicate the front panel functions. Note that all characters are
uppercase and no control characters such as <CR> (carriage return) or <LF> (line feed)
need to be sent. If they are sent, they will be ignored. All ASCII characters other than the
ones listed below will also be ignored.
The following commands are recognized by the WILDCAT scale when the output mode
is programmed as either demand mode or continuous output.
Command Function Description
C Clear Clear tare value
T Tare Performs a pushbutton tare
P Print Transmit data or set print bit in continuous output
S Print Transmit data or set print bit in continuous output
Z Zero Zero the scale (if within range and no-motion)
