4.9 Connection of Peripherals
1.
Make sure that both connector cases (frame ground) of the RS-232C cross cable (shielded 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/Printer using an earthing
wire in order to prevent difference in the electrical potentials.
