Purpose
The Genius balance has a serial
communications port (labeled
“PERIPHERALS”) to which you can
connect a computer, a remote display
or an external checkweighing display.
You can use an on-line computer to
change, start and/or monitor the func-
tions of the balance and the application
programs.
The communications port also provides
data output port lines for the over/under
checkweighing program. This port
can also be used to connect a hand or
foot switch.
! Warning When Using Pre-wired
RS-232 Connecting Cables
RS-232 cables purchased from other
manufacturers often have incorrect pin
assignments for use with Sartorius bal-
ances. Be sure to check the pin assign-
ment against the chart before connect-
ing the cable, and disconnect any lines
marked “Internally Connected” (e.g., pin
6). Failure to do so may damage or
even completely ruin your balance
and/or peripheral device.
