I have had way too much experience with USB to 9 pin serial adapters.
School of hard knocks taught me that the inexpensive (cheap) USB adapters won’t work.
I have found that the Startech adapter does work well. Here is a link: https://www.startech.com/Cards-Adapters/Serial-Cards-Adapters/1-Port-USB-Serial-RS232-Adapter-Cable~ICUSB2321F
Cost should be less than $ 30.00 – well worth the few extra dollars.

We use an Inovonics 730 with the serial input.
I have not tried it, but might a USB to Serial cable adapter work for you?

Subject: [CRTech] RDS Encoder?
What are you all using to get full function RDS encoding into your signal? I keep looking at Inovonics, but they still use 9 pin serial ports to get data. My automation computer does not have a serial port nor does it have any slots available to put one in. Are there any dynamic encoders out there that use a usb connection from computer to encoder?
