RS485 is more industry-based communication which is developed for a network of multiple devices that can be used over long distances and at greater speeds too. It operates on a differential signaling method of measurement rather than voltage measurement with respect to GND pin. The RS485 signals are floating and each signal is transmitted over a Sig+ line and a Sig- line. The RS485 receiver compares the voltage difference between both lines, instead of the absolute voltage level on a signal line. To send this data from your PC through the CAT cables you will need a converter to convert the UART data to the RS485 protocol, you can use a MAX485 Converter or this USB to RS485 Adapter for this task. This has an edge over MAX485 as we can directly plug into the USB port and no need to separately power it and you can just plug two wires onto the ports and use it. It is fully compliant USB 2.0 standard and backward compatible with USB1.1.
