Single-Computer KVM Extender
The Black Box ACU5051A extends one VGA, USB 2.0 and stereo audio source up to 164 feet over a single CATx cable. A local unit connects to the computer while a remote unit provides console access with a built-in four-port USB hub. The system supports 1920 x 1440 video resolution and dual-access operation. Both 110 V and 220 V AC input voltages are accepted.
Server Rooms and Multi-Workstation Desks
IT teams can place a server in a secure rack and operate it from a distant console without running long VGA and USB cables. The integrated USB hub on the remote side simplifies keyboard, mouse and peripheral connections. Buyers who need to switch between multiple computers or require digital video formats such as DVI or HDMI should look at a different product class.
164-Foot CATx Extension Distance
The extender reaches 164 feet over standard CATx cabling while maintaining 1920 x 1440 resolution and transparent USB 2.0 performance. This distance figure is the primary constraint for cable routing and rack placement.

Questions about this item
How do I install the ACU5051A KVM extender and which connection step is often missed?
Connect the local unit to the computer using the supplied VGA cable, USB A-B cable and audio cable, then link both units with a CATx cable up to 164 feet; the step often missed is plugging the IEC 320 power cord into each unit and the 110 V AC or 220 V AC supply before powering on.
What maintenance or replacement will the ACU5051A need during its service life?
The extender has no user-serviceable parts; if the power supply or any CATx link fails, replace the affected module or cable, and keep the RJ-45 ports and 3.5 mm audio jacks free of dust.
What limit appears first when the ACU5051A runs continuously at 1920 x 1440 resolution?
The CATx link is rated for 164 feet; exceeding that distance degrades the VGA signal and USB 2.0 transparency before any other limit is reached.
