Data Input Formats
Commands can be input via the balance interface port to control the
balance functions.
Control commands are distinguished according to those with upper-case
letters, or special characters, and those with lower-case letters.
Control command can include up to 13 characters. each character must be
transmitted with a start bit, a 7-bit ASCII-coded character, a parity bit and
one or two stop bits.
Formats:
ESC f X CR LF
ESC K CR LF
Where:
ESC = Escape (ASCII 27)
K, f = Command characters
X = Number = Underline (ASCII 95)
CR = Carriage return (ASCII 13)
LF = Line feed (ASCII 10)
The characters CR and LF do not have to be transmitted in the data string.
Control Commands with Upper-Case Letters or Special Characters
ESC P CR LF (Print; activate/block auto print)
ESC S CR LF (Restart/self- test)
ESC T CR LF (Tare)
ESC P CR LF (Internal calibration adjustment)
The “P,” “T” and “Z” commands do not affect the menu code settings of
the balance to reinitialize (turns the scale off and back on again). The “S”
command causes the processor to reinitialize (turns the scale off and back
on again).
The balance will operate according to the commands available up until the
processor is reinitialized. Once the balance has been turned on, the
processor will always recognize the codes entered by the user in the
balance operating menu.
ESC O CR LF (Block the keys)
ESC R CR LF (Release the keys)
ESC K CR LF (Very stable)
ESC L CR LF (Stable)
ESC M CR LF (Unstable)
ESC N CR LF (Very unstable)
