Original Press Release:
USB-to-RS422/485 Adapter - Self-Powered Long-Distance Communication for Laptops
Fairport, New York. USB-COMi is a ready-made cable solution for allowing RS422 serial devices to talk to newer USB PC's. The cost-effective USB-COMi is based on FTDI's single chip FT232BM USB UART i.c. for transferring serial data over the Universal Serial Bus. USB-COMi is a serial-port USB Adapter housed in a strong plastic enclosure and designed for rugged application areas. It adds an RS422/485 Windows Serial Com port (Virtual COMports) but uses the laptop's USB connection - great for laptop PCs without a serial port! USB Plug-and-Play allows easy serial port expansion and requires no IRQ, DMA, or I/O port resources. Connection to USB is via the 0.9m detachable USB cable included. USB-COMi Adapters have an internal jumper strip which allows configuration in either RS-422 or RS-485 mode, ideal for peripherals such as POS and Industrial Control devices.
USB-COMi features a full set of RS422/485 data and control signals (TX-, TX+, RX+, RX-, GND, RTS-, RTS+, CTS+, CTS-) on its DB9M connector. USB-COMi has an internal 128 byte transmit buffer FIFO and a 384 byte receive buffer FIFO and supports data transfer rates of up to 1 million bps. No external power supply is required as USB-COMi takes its power from the USB bus.
USB-COMi comes complete with drivers for Microsoft Windows98/ME/2K/xP (Apple OS-8/9/X and Linux drivers are also available).
