Procedure to Connect the Serial and I/O ports to an External
Cable
In the following picture, it has showed the right procedure to connect a cable
to the I/O or to the serial port.
A shielded cable of 3 m maximum length has to be utilized for both serial and I/O
port connection. Remove the plastic protection on both the ends of the cable
(picture b) and after it is necessary to connect the wires to the single pins like
showed in the picture c.
NOTE
Take care to have a good contact between the metallic case and the external
shield of the wire. Moreover, this operation has to be done at least on the
controller side.
In this way, you will be sure to reduce the influence of the external noise and
to accomplish the EMC requests. In picture d is showed the cable assembled.
