Interface Switch Command - Intrepidcs API
Main

When the neoVI Green device powers up it enters RS232 mode for neoVI to host communications.  Host to neoVI communications are always active on both RS232 and USB. This allows either port usable for sending a command to change between RS232 and USB for neoVI to host communications. This command is called the interface switch command.

neoVI Blue will always automatically select USB when the USB is plugged in. Therefore, this command is not required
