USB 2.0 extender with four ports

The SIIG JU-EX0311-S1 extends USB 2.0 signals up to 262.47 ft over a single RJ-45 cable. It provides four downstream ports for keyboards, mice, printers or other peripherals. The metal enclosure measures 2.1" by 2.8" by 1" and includes a power adapter and USB Type A to B cable. TAA compliance suits government or institutional procurement.

Passive cooling with external power

The unit relies on its metal housing for heat dissipation without any moving parts. An included AC adapter supplies the power needed to drive the link and the four connected devices. No fan noise is generated during operation. RoHS certification confirms restricted hazardous substance levels.

Single-cable deployment for remote peripherals

A single Category 5e or better network cable carries data and power between the local and remote units. The extender frees the host computer from lengthy USB runs that would otherwise exceed standard limits. It requires an available USB 2.0 Type-A port on the host and a nearby mains outlet for the power adapter. Builders needing more than four ports or USB 3.x bandwidth should consider alternative solutions.

Questions about this item

How do I install the 4-port USB 2.0 extender and what step is often missed?

Connect the local unit to the PC using the included USB 2.0 Type A to B cable, link the remote unit via a Cat5e or better RJ-45 cable up to 262.47 ft, plug the power adapter into the remote unit, then attach peripherals to the four USB ports. The step often missed is powering the remote unit before connecting devices.

What maintenance or replacement will the extender need later?

The unit has no user-serviceable parts. If the power adapter fails, replace it with a matching 5 V DC supply. The RJ-45 cable can be swapped for any Cat5e or higher patch cord up to 262.47 ft. Keep the metal enclosure vents clear of dust.

What limit appears first during sustained use of all four ports?

The shared USB 2.0 link caps total throughput at the interface maximum, so simultaneous high-bandwidth devices will contend for bandwidth before the 262.47 ft cable distance becomes a factor.
