! 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
scales. Be sure to check the pin
assignment against the chart below
before connecting the cable, and dis-
connect any lines marked “Internally
Connected”. Failure to do so may
damage or even completely ruin your
scale and/or peripheral device.
