Operating the Scale
Interface Port
Purpose
The scale has an interface port to
which you can connect a computer, a
remote display or an external check-
weighing display via Zener barrier.
You can use a PC to change, start
and/or monitor the functions of the
scale and the application programs.
The interface port also provides data
output lines for the over/ under
checkweighing program. This port
can also be used to connect a hand
or foot switch.
! Warning: When Using Prewired
RS-232 Connecting Cables!
The pin assignments in RS-232 cables
purchased from other manufacturers
are often incompatible with Sartorius
scales. Check the pin assignments
against the chart before connecting
the cable, and disconnect any lines
marked “Internally Connected” (e.g.,
pin 6). Failure to do so may damage
or even completely ruin your scale
and/or peripheral device.
