PLUGABLE USB TO RS-232 DB9 SERIAL ADAPTER for RS485


#1

Can I use this for RS485 serial connection? If so, what is the DB9 pin assignment? Does the Android driver support RS485 connection?

Thank you for posting your question.

RS-232 and RS-485 use a different method of representing logical ones and zeros, so there is no pin-to-pin correspondence between the two. You would need to get an adapter specifically designed for RS-485. This may be difficult for an Android device, because if the driver for a particular adapter is not already supported in an Android device, it is nearly impossible to add after the fact.

This article has some good information about the differences between RS-232 and RS-485:

Hi Dave, thanks for the reply. I was asking because i read from prolific (tw) that their PL2303HXD can support RS485 interface.

Yes, but to do that, it would probably need a different interface chip than the one we use.
