DIGITUS USB Extender - USB 2.0 4x USB-A ports 150m For use with CAT6 (or higher) cable

The Digitus USB 2.0 CAT extender DA-73120 lets you extend USB connections up to 150 m using a CAT 6 (or higher) cable. The kit includes a transmitter (TX) and receiver (RX) and provides four USB-A ports at the receiver, enabling connection of several peripherals without moving the host PC. The metal housing and integrated protections make it suitable for offices, conference rooms, surveillance setups and industrial environments where robust, long-distance USB connections are required.

Advantages

The extender supports USB 2.0 data rates up to 480 Mbps and enables a single USB source to be distributed to multiple devices via the RX unit with four USB-A outputs. The transmitter is powered from the host PC so no extra supply is needed for the TX, while the receiver accepts a DC 5V/1A adapter. Built-in ESD, overvoltage and short-circuit protection reduce risk to connected devices. The unit is plug & play, requires no driver installation, and its metal housing increases durability in demanding environments.

Suitable for

• Extending USB peripherals in large offices and conference rooms
• Connecting remote cameras, scanners and printers
• Surveillance and monitoring systems requiring distant USB devices
• Industrial workstations where the host PC must remain in a protected location

How to use

Connect the transmitter unit to the host PC using the USB-A cable, and link the TX and RX units with a CAT 6 (or higher) cable via their RJ45 ports. Plug the DC 5V/1A adapter into the receiver if required. Attach up to four USB devices to the receiver’s USB-A ports. The transmitter draws power from the host, and the system is ready to use without additional drivers—simply connect and operate the connected USB peripherals.

Recommendations

For reliable performance, use a high-quality CAT 6 or higher shielded cable and avoid running the cable alongside high-voltage lines. If multiple extenders are cascaded, ensure proper network switching and adhere to the specified maximum distances. Use the supplied DC 5V/1A adapter for the receiver to maintain stable operation when several powered USB devices are connected.
