! 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/scales. 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/scale and/or peripheral device.
