Black Box USB Hub, RS-232/RS-422/RS-485, 4-Port - USB - 4 x Number of Serial Ports External

Why install an internal serial adapter to get extra COM ports when using an external USB connection makes more sense? Our USB Hub converts your serial devices to USB-adaptable peripherals without sacrificing serial connection speeds. The hub features 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, this hub is among the fastest USB serial devices in the industry! It''s also ideal for connecting devices in harsh environments where communication lines may be affected by noise and voltage spikes. Not only does the USB Hub give you industrial-quality serial connections, but it also supports automatic RS-485 data enable/disable and includes a DB9 connector that''s backward-compatible with PCI and ISA RS-422 products.
