Interface Port
Purpose
Your pipette calibration balance comes
equipped with an interface port for
connection to a computer or other
peripheral device.
You can use an on-line computer
to change, start and/or monitor the
functions of the balance and the
application programs.
The interface port also has four data
output port lines for the over/under
checkweighing program.
!
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
balances. Be sure to check the pin
assignment against the chart on the
right 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 balance and/or peripheral device.
