I've got an RJ45 to D9 RS232 Adapter that I want to use to control an RS232 device in the following config:




Laptop RJ45 Ethernet port -> Cat6 patch lead -> D9 RS232 adapter -> RS232 Device




Would the above work ?






serial rs232

    The RJ45 to DB9 adaptor is almost certainly just connecting pins on the RJ9 connector to connectors on the RJ45 - I've yet to come across any of these devices with any logic in them - and a lot of logic (and configuration) would be required as Ethernet and serial connections are very different.

No. Ethernet ports can't transmit or receive RS-232 signals.



If your laptop has a traditional DB9 RS-232 serial port, use that with the appropriate serial cable. If it doesn't, use a USB to RS-232 serial adapter.

            One-line joke

            A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
