About Multiport(Multi-N) USB series
USB is a complex word of “Universal”, meaning all peripheral devices use the same connector, and “serial”, meaning
devices are connected as a daisy chain through serial transmission. USB is an interface suggesting a solution to
inconvenience and inefficiency caused by slow speed and limited device connection of existing external ports (serial
or parallel).
Compared to external ports that were only used to connect devices such as modems, printers and scanners, USB is
powerful in that it connects all types of basic peripheral devices that were each connected via different types. Also,
when a new device is plugged, it is auto-detected without any rebooting or setup process, enabling 127 connections
maximum. Installation is handy since PnP (plug and play) is supported. No extra equipment is needed since most of
the main-board chipsets include the USB controller.
USB cable type supported is type A, which can utilize the USB port of a computer or the USB hub. This product
obtains power from USB, and this makes the product powerful since no external power supply is required.

About latching USB
All USB Multiport products of SystemBase have latches on USB connection.
Unlike traditional screw-tightening model which require specific cables and connectors, latching USB cable provides
locking function without the need to replace the product.
※ USB latching function may be limited to some manufacturers.
※ For normal mounting, you might hear a ‘click’ sound.
※ To facilitate connection and disconnection, press lightly on the spring button and sweep it.
