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 weighing systems. Be sure to check the pin assignments against the
chart below before connecting the cable, and disconnect any lines identified differently
from those specified by Sartorius (e.g., pin 6).
Failure to do so may damage or even completely ruin your weighing system and/ or
peripheral device.
