    RS-285 is probably a typo. Besides RS-232 and RS-485 are not cable. CAT 3, 4, 5, 5e, 7 etc are cable standards.

    Telephone uses CAT 3 or better cable.
    Ethernet CAT 4 or better depending on the standard. e.g. 10baseT, 100baseT, 1000baseT.

    The 100 is for 100 mb/sec, base is base, T is twisted cable

    Pass me the 1000baseT cable. What? Pass me the Ethernet cable. OK. Expected use. Technically incorrect.
