USB to RS232

Crestron_Programmer All Messages By This Member #162648 Hey Guys, Is there a way to convert a USB signal to RS232? Thank you
Anthony Desimone #162649 Not easily. You need a driver (and hardware of course) for the particular usb device. toggle quoted message Show quoted text --- In Crestron@..., "Sebastian" <s.marszalek11@...> wrote: Hey Guys, Is there a way to convert a USB signal to RS232? Thank you

Jeremy Weatherford All Messages By This Member #162659 If you have a USB RFID reader, you'll need to write a PC app to scan the cards and send something (232 or IP) to Crestron. Otherwise you need an RS232 RFID reader to use with Crestron. On Fri, Aug 10, 2012 at 8:10 PM, sebastian marszalek <s.marszalek11@...> wrote: It's an RFID reader.

Crestron_Programmer All Messages By This Member #162661 I also have a TTL to RS232 but It doesn't seem to work very well. -- Sebastian Marszalek
jrw_96 All Messages By This Member #162666 This doesn't look very hard (though the lit. is lacking from my brief look over). It seems that they are doing serial over usb as it stands. You might send them an email explaining your needs and get a response that may be helpful to you...

jrw_96 All Messages By This Member #162667 Did you get a copy of the protocol for the ttl to rs232 device?

Crestron_Programmer All Messages By This Member #162676 Thanks for all your suggestions guys, It turned out to be a loose power connector on the TTL to RS232 (See attached.) -- Sebastian Marszalek
