Frequently Asked Questions - USB-Pair DVDO

How far can the DVDO USB-Pair extend USB signals?

The DVDO USB-Pair can extend USB 2.0 signals up to 50 meters (165 feet) using a Cat 5e or Cat 6 cable. Performance may vary depending on cable quality and distance.

What type of cable do I need to connect the transmitter and receiver?

You need a Cat 5e or Cat 6 cable with T568B straight-through wiring. Connect the cable from the UTP OUT port on the transmitter to the UTP IN port on the receiver.

Do I need to install drivers?

No, the device is plug-and-play and requires no driver installation. It is supported by Windows, Mac OS, and Linux natively.

Can I power the receiver without the external power supply?

Yes, the receiver can be powered via Power over Ethernet (PoE) from the transmitter if the transmitter is powered by the USB host. However, for high-power USB devices, it is recommended to use the included 12V DC power supply.

How many USB devices can I connect?

The receiver has 4 USB 2.0 ports for connecting devices such as keyboards, mice, cameras, and flash drives. The total current per port is up to 500 mA.

Is it compatible with USB 3.0 devices?

The extender is USB 2.0 (up to 480 Mbps) and backward compatible with USB 1.1 and 1.0. It will work with USB 3.0 devices but only at USB 2.0 speeds.

What operating systems are supported?

The USB-Pair supports Windows, Mac OS, and Linux without additional drivers. It is compatible with both 32-bit and 64-bit systems.

My receiver has no power, what should I do?

First, check that the power adapter is connected firmly to the receiver and the wall outlet. Ensure the transmitter is connected to a powered USB host. If using PoE, verify the Cat cable is properly connected. If still no power, try replacing the power supply.

Can the transmitter be powered only by the USB port of my computer?

Yes, the transmitter can be powered solely by the USB host (e.g., your computer) via the included USB-A to USB-B cable. In this case, the receiver can also draw power from the transmitter through the Cat cable (PoE).

How do I clean and maintain the extender?

Clean the device with a soft, dry cloth only. Do not use any liquids, solvents, or abrasive cleaners. Ensure the unit is unplugged before cleaning. Keep ventilation openings unobstructed.
