A balance and a printer can be attached to RS232 interface 2 at the same time with
the aid of the 6.2125.030 Socket-outlet adapter. The balance must then be plugged
into the ”data in” port of the socket-outlet adapter.
The initial mass is transferred as a number with up to 6 digits, sign and decimal
point. Units and control characters sent by the balance are not transferred. With the
aid of a special input device supplied by the balance manufacturer, not only the ini-
tial mass but also sample identifications and methods can be put in from the bal-
ance. The addresses of the identification or method must be preselected on the in-
put device:
Balance Method Id#1 Id#2 Id#3
Sartorius METH or 27 ID.1 or 26 ID.2 or 24 C-20 or 23
Mettler (AT) D (Mthd) C (ID#1) B (ID#2) A (c20)
