Interface Description; Data Output; Data Transmission Formats; Algebraic Sign - KERN EW-N Series Operating Instruction

8.3 Interface description

The output format, output control, transfer speed and parity bit can be set following
the choice of a certain operating mode. The various possibilities are described in
chap. 7.2.2 "Parameters for the serial interface ".

8.4 Data Output

8.4.1 Data Transmission Formats

By selecting the corresponding function at your balance one of the two following data
formats can be set:
• 6-digit data format
(excl. model KERN EW-120-4NM)
Consisting of 14 words including the final signal; CR=0DH, LF=0AH (CR=return
travel / LF=line feed)
1 2 3
P1 D1 D2
• 7-digit data format
1 2 3
P1 D1 D2 D3
Note: The 7-digit format is identical with the 6-digit format except for the addition-
al signal D8.
