1. Overview
YKUP is a USB upstream switch that allows two hosts to share the same USB device. The user
switches the device between the two hosts simply by pressing the on-board push-button.
For example if you want to use the same keyboard with two PCs, without the need to physically
switch the USB cable connection between them, YKUP is for you. With YKUP you can switch the
keyboard from one PC to the other just by pressing a push-button.
2. Description
YKUP switches the USB device, connected to the downstream port, between the two upstream ports.
To switch between upstream ports the user presses the on-board push-button.
Additionally, two pins are available to connect an external switch which can also be used to trig-
ger the switch.
At power-on the YKUP defaults to the Upstream 1 as the active port.
