USB 3.2 Gen1 CAT-Extender της DIGITUS DA-73121 — 5 Gbit/s, 4 θύρες (3× USB-A, 1× USB-C), 100 m, τροφοδοσία DC

The DIGITUS USB 3.2 Gen1 CAT Extender DA-73121 allows USB devices to be connected over distances up to 100 m using a CAT 6A (or higher) cable. It extends USB 3.2 Gen1 signals at data rates up to 5 Gbps and provides four downstream ports (three USB-A and one USB-C). The transmitter is powered via the host device and the receiver is DC powered, enabling remote placement of cameras, printers, hard drives, keyboards and other USB peripherals without the usual cable length limitations.

Advantages

This extender supports high transfer speeds up to 5 Gbps while maintaining compatibility with USB 2.0 and 1.1 devices. It combines a multifunctional four-port hub with Power-over-Cable functionality so only the receiver requires an external DC power supply. Integrated protection circuits provide ESD and overvoltage protection. The metal housing and compact dimensions ensure robust operation in office, conference or industrial environments. Installation is plug-and-play and requires no additional drivers.

Suitable for

• Extending USB peripherals in large offices and conference rooms
• Connecting remote surveillance cameras and security systems
• Attaching printers, scanners and external hard drives at distance
• Industrial workstations and production environments requiring durable connections

How to use

Connect the transmitter unit to the host computer using the USB-C input. Link the transmitter and receiver with a CAT 6A (or higher) cable via the RJ45 ports. Attach up to four USB devices to the receiver’s USB-A and USB-C downstream ports. Provide DC 12V/3A power to the receiver; the transmitter will be powered by the host device. The device is plug & play and requires no driver installation. Observe the specified maximum cable length and operating temperature range for reliable operation.

Recommendations

Use a certified CAT 6A (or higher) cable for full 5 Gbps performance and to reach the 100 m maximum distance; avoid running the cable alongside high-voltage power lines and ensure the receiver’s DC adapter meets the required 12V/3A rating for stable operation.
