Why install an internal serial adapter to get extra COM ports when using an external USB connection makes more sense? Our USB Hubs convert your serial devices to USB-adaptable peripherals without sacrificing serial connection speeds. The hubs feature high-speed UARTs with 128-byte FIFO transmit buffers and 384-byte FIFO receive buffers. With data rates of up to 921 kbps for RS-422/485 and 460 kbps for RS-232, these hubs are among the fastest USB serial devices in the industry!
