Pretty sure the newer innovonics can do IP as well. I have an innovonics, a 2wcom, and a couple PIRA. I use 9pin or IP on all mine. You could try a usb to serial adapter, but honestly I’d just use IP rather than usb. Seriel works good for me over my STL. Latency over IP shouldn’t bean issue if your on a LAN, which I’m assuming you would be if USB is in the running. Heck it really isn’t an issue over WAN given the low Data rate of RDS there is usually a bit of latency anyway.

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?
