OVERVIEW
Link a PC’s video output to a display device located up to
450 feet (137.2 m) away using CAT5 shielded twisted-pair cable.
Or use CAT5 unshielded twisted-pair cable (UTP) to connect a
PS/2 ® keyboard and mouse up to 350 feet (106.7 m) away from your CPU and display monitor.
VGA Baluns and Keyboard/Mouse Baluns are perfect for classrooms, digital signs, and presentations. They use readily available and inexpensive CAT5 cable. And no power supply is required because the baluns and extenders derive ultra-low power from the interface.
In a digital sign application in an auditorium, you can control the video source at the back of the room and the video sign display at the front of the room. In a classroom application, you can control the keyboard and mouse at the back of the room, while your partner controls the video source and display at the front of the room.
The VGA Baluns must be used in pairs. The VGA Source
Balun (AC640A) connects to the local source (the CPU), and the VGA Display Balun (AC641A or AC642A) links to the remote display.
The Keyboard/Mouse Baluns must also be used in pairs.
The local unit (AC643A) connects to the CPU. The remote unit (AC644A) connects to the keyboard and mouse.

Why Buy From Black Box? Exceptional Value.
Exceptional Tech Support. Period.
Recognize any of these situations?
• You wait more than 30 minutes to get through to a vendor’s tech support.
• The so-called “tech” can’t help you or gives you the wrong answer.
• You don’t have a purchase order number and the tech refuses to help you.
• It’s 9 p. m. and you need help, but your vendor’s tech support line is closed.
According to a survey by Data Communications magazine, 90% of network managers surveyed say that getting the technical support they need is extremely important when choosing a vendor. But even though network managers pay anywhere from 10 to 20% of their overall purchase price for a basic service and support contract, the technical support and service they receive falls far short of their expectations—and certainly isn’t worth what they paid.
At Black Box, we guarantee the best value and the best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just the right component for your application.
Don’t waste time and money— call Black Box today.
