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 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.
