What is USB MultiPort?
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’s auto-detected without any rebooting or
setup process, enabling 127 connections maximum. Installation is handy since PnP is perfectly
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 the PC or the USB hub.
This product obtains power from USB, and this makes the product powerful since no external
power supply is required.

①Loosen the two screw on the bottom case.
②Remove the side cap.
Look at the rear side of case, you can find the small grooved.
③Top cover is slid to the inside of the case.

Multi-1/USB Ver4.0
10M: Not use Slew Rate Limit ability. Maximum communication speed
921.6Kbps in this mode.
250K: Use Slew Rate Limit ability. Communication speed is limited under
250Kbps.
Slew Rate Limit allows communication without errors by activating slew-rate driver to reduce
reflection waves and EMI electromagnetic waves. However, communication speed is limited
when it is used.
