Hi
Im hoping someone can help me out!
i have a PLC SLC 5/03 and i want to connect the DB9 port with DH485 protocol to a computer 100 fts from there, is there any problem with the distance? and what kind of cable should i use , i already connected with my laptop with a USB-serial with a null modem cable RS232 (i did the cable by my self) but for the distance i cannot keep using that protocol so what is the recommendation?
