Sartorius LA Reference Series Operating Instructions Manual page 118

Interface Description
Purpose
Your LA Reference balance comes
equipped with an interface port for
connection to a computer or other
peripheral devices.
You can use an on-line computer to
change, start and/or monitor the func-
tions of the balance and the application
programs. The interface port also has
four control lines for the over/under
checkweighing program. You can also
connect a hand switch or foot switch.
! Warning When Using Pre-wired
RS-232 Connecting Cables!
RS-232 cables purchased from other
manufacturers often have incorrect pin
assignements for use with Sartorius
balances. Be sure to check the pin
assignment against the chart below
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.
