6.6 TRANSMISSION PROTOCOLS

The weight data transmission on the PC and PRN serial ports may take place in 3 formats: STANDARD STRING,
EXTENDED STRING or MULTISCALE STRING.

6.6.1 STANDARD STRING

STRING TRANSMITTED IN THE DEPENDENT CHANNEL AND INDEPENDENT CHANNEL MODE

[CC]hh,kk,pppppppp,uu + CR + LF

STRING TRANSMITTED IN THE TRANSM MODE:

[CC]hh,pppppppp,uu + CR + LF

in which:

[CC]

INSTRUMENT CODE IN THE FORMAT OF TWO ASCII DECIMAL DIGITS

ONLY IN THE CASE THAT THE 485 PROTOCOL IS SELECTED (FOR EXAMPLE 00).

Under load (not transmitted in the "TRANSM" mode)

Over load (not transmitted in the "TRANSM" mode)

Stability of the display

Instability of the display

Comma character

Net Weight

Gross Weight

Gross weight with sensitivity times 10

Value in micro volts relative to the weight

Value in converter points relative to the weight

Comma character

pppppppp

8 digits (including any sign and decimal point) which identify the weight. The insignificant

digits are filled with spaces. Through the MVOL and RAZF command the indicator transmits
the relative value on 10 digits instead of 8.

Unit of measurement "kg" "

g" "

t" "lb" "mv" (microvolts) "vv" (converter points)

Carriage Return (13 ascii decimal character).

Line Feed (10 ascii decimal character).

The transmitted weight is the GROSS weight (GS) if no TARE WEIGHT has been entered; otherwise, the NET
WEIGHT (NT) will be transmitted.
