10.2 Serial Connections :
In order to create the serial connection use a shielded cable, making sure that only one
of the two shield ends is groun
ded. If the cable has more conductors than those used,
connect the free conductors to the shield.
The serial connection wire must be a maximum of 15 metres long ( EIA RS-232-C
standards), in addition to which it is necessary to adopt the Rs422 interface th at the
instrument can be equipped with.
The cable must not be channelled with other cables (i.e. outputs connected to remote
switches or power
supply wires), but must follow its own route. The PC used for the
connection must conform to the EN 60950 standard.
