The DVI RS232 Extender
Extending state-of-the-art digital video displays, computer monitors and touch
screens has never been easier. Distances up to 150 feet at 1080p resolution (300
feet at 1080i resolution) are guaranteed to perform beautifully, giving you a reliable
method of all-digital extension while streamlining your installation cabling needs.
How It Works
You simply connect the DVI RS232 Extender sender unit to your DVI and RS-
232 source using the supplied cables. Your RS-232 device and the DVI display
plugs into the DVI RS232 Extender’s receiver unit. Two CAT-5 cables connect the
sender and the receiver units to each other allowing for up to 300 feet of extension
(300 feet at 1080i resolution or 150 feet of extension at 1080p resolution).
