RS485 to RS232 conversion?
There exists such conversion but it's not as simple as putting a cable with RS-232 standard male cable to a RS-485 standard female cable or vice versa. The RS-485 standard protocol is very similar to RS-232 in terms of serial communications. However, the RS-485 has Differential Signaling, which basically means that it transmits information using two complementary signals.



NOTE: The circuit diagram above is an example that can be found here of how this conversion may work. This could be one way you can differentiate a signal. As far as the materials you need, that's up for you to decide. If you're purchasing an adapter, I will not be able to provide recommendations. There are multiple ways to approach this problem, this is just one example.
