RS-232C USB Conversion & DB9 Male-to-DB9 Male Cross Cable Set of 2 These are conversion cables I previously purchased from Akizuki Denshi to use RS232C. I used them to update devices that connect via RS232C using USB on a laptop. They were recognized by the laptop, but I couldn't confirm their operation because I don't have any RS232C devices. (I think there shouldn't be any problems) I no longer have the devices, so would anyone like to use them? - Cable Type: RS-232C USB Conversion - Connector Type: DB9 Male-to-DB9 Male Cross This is a set of 2 cables. Thank you.
