One component of a robust solution that, when paired with a base unit (part 89008 or 89009, sold separately), extends your VGA & 3.5mm audio signals up to 300 meters over a Cat 5E UTP cable, & distributes the signal to up to 4 monitors, projectors, or displays. Ideal for applications when your VGA monitor needs to be placed beyond the average 30 meter VGA cable limitation, and/or you want to split the signal to multiple displays. Driving a VGA signal over Cat 5E helps you take advantage of your UTP cable infrastructure already there for a cost-effective & reliable installation. The Tru Link VGA over Cat 5 solution is ideal for applications when you need to place your computer in remote location. This is common in digital signage applications for retail stores, houses of worship, classrooms, & boardrooms where you need video presentation in one room, but want the computer to be out of sight & in a safe & secure environment. With the Tru Link VGA + 3.5mm audio over Cat 5 Extender, you can place your display across the room, on another floor, or in another building while your computer remains in a convenient location.
