USB to Serial

Dear Cedrus –

Quick question… does connecting the SV1 to a USB port via a USB-to-serial connector change, increase or otherwise affect timing or latency? If so - will it be in a predictable/measurable fashion?

Thanks a lot!

Yes, using a USB-to-serial port adapter will increase latency. “How much” depends on the driver supplied by the adapter’s vendor, unfortunately. The ones made by FTDI (sold in the U.S. by Saelig) and Keyspan tend to have shorter latencies but still in the order of a few milliseconds.
