Hi group, I have (2) 6-foot lengths of cable, one is the HMI serial comm cable between a PLC and an Automation Direct EA9 HMI ....the other cable goes between a 2nd PLC serial port and a printer. The wiring is not routed with high voltage lines and the highest voltage in the panel is 110V. How important is shielding in this case? The cabling is mostly hand-made-up and I have to install 2 DB9 connectors basically just as couplers within each cable and bringing the shields thru each connector will be a bit of a pain.
Any advice? Thank you.
