RS 232 interface

We recommend shielded cable for the RS 232 interface.
If you use unshielded cables, the interface may malfunction.
} Earth the cable shielding on both sides (e.g. on a bus bar).
}
Transient currents can be anticipated on longer cables. If this is the case you should
use equipotential bonding cables.
}
With the supply voltages switched off, connect the interface (X6) on the servo amplifier
to a serial interface on the PC via a null modem cable.
