Serial RS232 connection (COM1)

To make the serial connection, use a shielded cable, taking care to connect the shield to
one of the two ends. If the cable has more wires than those used, connect the free wires
to the shield

The serial connection cable must have a maximum length of 15 meters (EIA RS-232-C
standards), beyond which it is necessary to use the RS485 interface of the instrument.

The cable must not be channeled with other cables (e.g. outputs connected to contactors
or power cables), but must possibly follow its own path.

Serial RS485 connection (COM2)

The connection cable needs to be of a suitable type for serial RS422/RS485 communication
with 1 twisted pair wires for RS485 and relative shielding.

The cable must not be channeled with other cables (e.g. outputs connected to contactors or
power cables), but must possibly follow its own path.
