-2- SuperTT Dongle 1. Introduction EPU3D02ARSM is a new-generation USB 3.0 dongle integrated with U3TT technology designed by VLI Beijing System Product Division. EPU3D02ARSM can convert the USB 2.0/1.1/1.0 devices connected on the downstream port to USB 3.0 devices, allowing these USB 2.0/1.1/1.0 devices to use the upstream SuperSpeed signal path. EPU3D02ARSM can use only SuperSpeed path on the upstream facing port when connected to USB 3.0 host, so it is easy to use Active Optical Cable (AOC) to extend the transmission distance of USB 2.0/1.1/1.0 devices to more than 100 meters. Feature List • The downstream and upstream ports are compatible with USB 3.0 standard • Plug & Play support • No need for driver • Single 5Vpower supply, self-power • Downstream and upstream port with USB 3.0 Standard-A receptacle • Upstream port supports USB 3.0 AOC and active power supply for USB 3.0 AOC • Upstream port can connect to USB 2.0/3.0 host/hub • Downstream port supports USB 3.0/ 2.0 devices/hubs • In system firmware upgrading support • Energy-saving mode supported • Double-color LED for state indication 2.

-3- SuperTT Dongle 1. USB 3.0 downstream facing port 2. USB 3.0 upstream facing port 3. 5V DC Jack 4. Dongle status double color LED 3. Hardware Setup EPU3D02ARSM can be powered by external DC only. The external DC adaptor should have capacity to provide more than 1.2 amperes. The upstream port should be connected to the host/hub using standard A-A USB 3.0 cable or AOC. 1) Connect USB device to dongle downstream port. 2) If the USB device is self-powered, connect the external power of the device. 3) Connect the standard USB 3.0 A-A cable to the USB 3.0 host (or hub). 4) Connect the standard USB 3.0 A-A cable to the upstream port of the
-4- SuperTT Dongle dongle. 5) Connect the external +5V DC power of the dongle. Notes: the sequence of the steps is irrelevant. 4. Troubleshooting Guide 1. Device could not be enumerated by host Checking items listed below to clear this issue. a. Check your hardware, make sure it is setup as described in this guide b. Check if USB 3.0 hub and USB 2.0 hub have been enumerated c. Check your USB device and host, make sure they works normally d. Check the power, make sure the voltage is 5V and the green LED of the corresponding port is off e. Check the self-powered USB device power, make sure it is turn on f. Re-power the dongle, make sure the red LED flash twice. If not, the firmware or hardware may be broken. 2. Device does not work in USB 3.0 Mode a. Check you host, make sure it is a USB 3.0 host and is not disabled b. Check your cable between host and dongle, make sure it is a qualified USB 3.0 cable c. Check the USB Hub between host and dongle, make sure it is a USB 3.0 Hub and is not disabled d. Check if the USB 3.0 hub and USB 2.0 hub has been enumerated by the host 5. Frequently Asked Questions (FAQs) • Q: Can I connect USB 3.0 device on the downstream port? A: Yes. If you connect USB 3.0 device on the downstream port, the SuperSpeed signals will not transmit through the SuperTT but directly to the
-5- SuperTT Dongle USB 3.0 hub IC. • Q: What should I do if the devices are very far away from the host? A: If the distance between the devices and host is more than 7m, it highly recommended using AOC on the upstream port. The length of AOC can be up to 100m. • Q: How should I choose the adapter for EPU3D02ARSM? The DC adopter should have the capacity to output more than 1.2 amperes to provide enough power on the downstream port. Otherwise some power hungry devices such as USB hard disk diver will not function properly. EverPro Technologies Company Ltd. www.everprotech.com Copyright © 2014 EverPro Technologies Company Ltd.
