    so the 4000 ft the i tought is not for the protocol, they are for the port RS-485 wich uses DH485 protocol to comunicate, and my only option  with out repeaters is use that port right?
  2. 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?
