Hardware Setup

-
Important safety information regarding the placement of this device is provided on page 13. Please review it before proceeding.
-
Make sure that the power to all devices connected to the installation is turned off. You must unplug the power cords of any computers that have the Keyboard Power On function.
Cable Connection
To ensure proper operation, it is recommended that only Cat 5e or better, Unshielded Twisted Pair (UTP) Ethernet cabling be used to connect the Local unit to the Remote unit. The cable must have a straight-through conductor configuration with no crossovers and must be terminated with 8 conductor RJ-45 connectors at both ends. The combined length of any patch cords using stranded conductors must not exceed 10 meters.
To set up your UEH4002A installation, refer to the installation diagram on page 10 (the numbers in the diagrams correspond to the steps, below), and do the following:
- Use a USB 2.0 cable (included with this package) to connect the Local unit's USB Type-B Port to a USB port on the computer.
- Connect one end of a Cat 5e Ethernet cable to the Local unit's Link port.
- Connect the other end of the Cat 5e Ethernet cable to the Remote unit's Link port, up to 100 meters away.
- Plug the power adapter (included with this package) into an AC source; and plug the other end into the Remote Extender's Power Jack.
- Use USB cables to connect up to four USB peripheral devices to the Remote unit's USB Type-A ports.
- Check the host computer to ensure all device drivers and software install correctly.
Installation Diagram

Checking the Installation
After installing the hardware, use the information below to confirm all peripheral devices are connected and working correctly.
- On the Local (UEH4002AL) and (UEH4002AR) Remote units, check that the Power, Host, and Link LEDs are on and that the Activity LED is blinking. If the Link LED is permanently off, then the cabling between the Local and Remote unit is not installed properly or is defective.

Troubleshooting
The UEH4002A complies with USB 1.1 and USB 2.0 specifications governing the design of USB devices. However, ATEN does not guarantee that all USB devices are compatible with the UEH4002A, as there are a number of different configurations that may impact the operation of USB devices over extended distances.
Operation problems can be due to a variety of causes. The first step in solving them is to make sure that all cables are securely attached and seated completely in their sockets.
The following table provides troubleshooting tips. The topics are arranged in the order in which they should be executed in most situations. If you are unable to resolve the problem after following these instructions, please contact technical support for further assistance.
| Problem Cause Solution | ||
| All LEDs on Local unit are off. | The Local unit is not receiving enough power from the USB port. | 1. Ensure that the USB connection between the local and host computer is properly installed.2. Move the USB connector to another USB port on the host computer. |
| All LEDs on the Remote unit are off. | The Remote unit is not receiving power from the AC adapter. | 1. Ensure that the AC power adapter is properly connected to the Remote unit.2. Check that the AC adapter is connected to a live source of electrical power. Check that the Remote power LED is illuminated. |
| Link LEDs on the Local and Remote units are off. | There is no connection between the Local unit and Remote unit. | 1. Ensure Cat 5 cable is connected between the Local unit and Remote unit. Cat 5 or better cable, UTP with a straight through connector and no crossovers, and 8 connector RJ-45 connectors are used at both ends.2. If the Cat 5 cable is defective, connect a short Cat 5 patch cord between the Local unit and Remote unit to determine if the original Cat 5 cable is defective. |
| Link LED on Local unit is on, Host LED on Local unit is off. | ◆ The host computer is not powered on.◆ The Local unit is not connected to the computer.◆ The computer does not support USB hubs.◆ The UEH4002A is malfunctioning. | 1. Disconnect all USB devices from the Remote unit.2. Disconnect the Local unit from the computer.3. Disconnect the Remote unit from the AC power adapter.4. Reconnect the Local unit to the computer.5. Reconnect the Remote unit to the AC power adapter.6. In the Universal Serial Bus controllers section of Device Manager, check that the UEH4002A is recognized as a “Generic USB Hub”. |
| UEH4002A units were working, but the Host LED on Local/ Remote units started blinking. | The Remote unit is in suspend mode. The operating system may put the UEH4002A in suspend mode when the computer is put into a Suspend/ Standby state or when no USB devices are attached. | 1. Recover/Resume the operating system from Suspend/Standby mode (see your operating system's documentation).2. Attach a USB device to the UEH4002A. |
| All LEDs on both the Local unit and Remote unit are on, but the USB device does not operate correctly or is detected as an “Unknown Device” in the operating system. | ◆ The USB device is malfunctioning.◆ The computer does not recognize the USB device.◆ The application software for the device is not operating.◆ The UEH4002A is malfunctioning. | 1. Disconnect the UEH4002A from the computer.2. Connect the USB device directly to the USB port on the computer.3. If the device does not operate properly, consult the user documentation for the device.4. Update your system BIOS, chipset, or USB Host controller drivers from your System/Motherboard manufacturer’s website.5. If the device operates properly when directly connected to the computer, connect another device (of a different type) to the UEH4002A. Connect the UEH4002A to the computer.6. If the second device does not operate, the UEH4002A may be malfunctioning. Contact technical support for assistance.7. If the second device does operate properly, the first device may not be compatible with the UEH4002A. |
| USB device is attached to Remote USB port but Remote device LED is off. | A USB device must have the appropriate driver installed on the computer operating system. | 1. Install the required USB device driver on the computer operating system prior to attaching the USB device to the Remote unit. Please see your USB device manufacturer’s website for details.2. Consult your USB device documentation and power your USB device with the additional, USB device manufacturer supplied, power supply (if available). |
| USB devices are no longer functioning. | Overcurrent condition has occurred because USB device draws more power than can be supplied per USB specification (500mA). | Power cycle the Remote unit. |
| LED Host and LINK LEDs on Local/Remote units blink intermittently. | Firmware mismatch between the Local and Remote. | 1. Use a different Local/Remote pair which have the same firmware revision.2. Upgrade the Local/Remote firmware, contact technical support for assistance. |
