RS422/RS485 testing

  1. May 28, 2006 #1
    Hi all,

    The system is RS422 and need a RS422-to-RS232 converter to download source from the system to the RS232 terminal.

    Question # 1:
    I usually use my laptop to test RS232 loopback. The laptop doesn't support RS422, so how to test to see if the RS422-to-RS232 is working?
    (Sometimes, RS232-to-RS422 loopback works, but not on the contrary)

    Question # 2:
    Suppose the question1 is answered, and the system has a RTS controller. How to test with this controller?

    Question # 3:
    My major is not Networking and I don't think this is a Networking forum. So, if anyone knows free Networking forums, I would like to have the URL addresses.

    Thank you for any help.
