rs485 is a serial port sometimes through a rj45 jack.
rs485 is a serial port used for programing etc
TIA-485-A, also known as ANSI/TIA/EIA-485, TIA/EIA-485, EIA-485 or RS-485, is a standard defining the electrical characteristics of drivers and receivers for use in balanced digital multipoint systems. The standard is published by the Telecommunications Industry Association/Electronic Industries Alliance (TIA/EIA). Digital communications networks implementing the EIA-485 standard can be used effectively over long distances and in electrically noisy environments. Multiple receivers may be connected to such a network in a linear, multi-drop configuration. These characteristics make such networks useful in industrial environments and similar applications.
The EIA once labeled all its standards with the prefix "RS" (Recommended Standard), but the EIA-TIA officially replaced "RS" with "EIA/TIA" to help identify the origin of its standards.[1] The EIA has officially disbanded and the standard is now maintained by the TIA. The RS-485 standard is superseded by TIA-485, but often engineers and applications guides continue to use the RS designation.

RS485 is an electrical spec like RS232. It can be implemented using a variety of connectors, or no connectors at all. In fact, it would not surprise me at all if the most common termination means was just terminals of some sort with no connector at all.

RS-485 is used for bac-net or Lon networks, and as stated before, it is a serial communications protocol. The terminations that I typically use are just terminal strips that are part of the equipment that I am daisy chaining together.

I should mention that the RS485 standard is used for other things besides bacnet, I just wanted to use it as example.
