Vinculum Firmware User Manual
The Vinculum VNC1L device has two USB host ports as well as a combined serial UART, SPI or FIFO interface. The combined interface is selectable using a pair of pins connected to either pull-ups or pull-downs. The firmware for the Vinculum VNC1L allows a command Monitor port to be active on either the combined interface or one of the USB Ports. The main function of the Monitor is to allow an embedded device to communicate via the VNC1L’s UART, parallel FIFO or SPI interface port with USB slave peripheral devices.
Typical slave peripheral devices include USB Flash disks; FTDI’s FT232, FT245 and FT2232; as well as devices that are Printer class or HID (Human Input Device) class compatible. Other devices may also be supported if they have a suitable interface. For instance, CDC class equipment such as some mobile phones. The 2 USB Ports are referred to as Port 1 and Port 2 in this document.
