USB 2.0 extender for remote devices

This Monoprice Blackbird 139673 extends USB 2.0 signals up to 164 feet over a single Cat5e or Cat6 cable. It connects two USB devices to one host port and supports data rates up to 480Mbps. The unit is true plug and play with no drivers required. It suits offices, classrooms or industrial setups where peripherals must sit far from the host computer.

Powered receiver with bus-powered transmitter

The transmitter draws power directly from the USB host connection, so no extra outlet is needed at the source end. A 5 VDC 1A AC adapter is included for the receiver to maintain reliable operation at the remote end. Power consumption stays within standard USB 2.0 limits, producing no audible noise and negligible heat during normal use.

Replaces long USB cables or hub chains

This extender replaces passive USB cables that fail beyond 5 metres and avoids daisy-chained hubs that add latency and power issues. The jump is worth it when keyboards, mice, printers or scanners must operate at distances up to 50 metres from the PC. It is not for applications needing USB 3.0 speeds or more than two downstream devices.

Questions about this item

How do I install the Monoprice 139673 extender and what step do people often miss?

Connect the transmitter to the host USB port, link both units with a Cat5e/6 cable up to 164 ft, then plug the included 5 VDC 1A adapter into the receiver before attaching peripherals.

What maintenance or replacement will the Monoprice 139673 need later?

The unit has no user-serviceable parts; if the external 5 VDC 1A power adapter fails, replace it with an equivalent 5 V 1 A supply.

What limit appears first during sustained use of the Monoprice 139673?

The USB 2.0 480 Mbps bandwidth ceiling is reached before the 50 m distance limit affects throughput.
