CAUTION
To protect the system, keep the following in mind:
1. Make
sure that both connector cases (frame ground) of the RS-232C cross cable (shielded cable)/USB
cable are conductive. If they are not conductive, make sure that both connector cases of the cable are
firmly connected.
2. If this is not possible, connect the frame of the PBX to the frame of the PC using an earthing wire in
order to prevent difference in the electrical potentials.
Note
For pin assignments and maximum cabling distance, refer to
