Model AC1032A-2A Users Manual 5.3 Problem Solving FAQ 1. What are the Cable Length Limitations? The switcher cannot be used as an extender. Therefore it is best to plug the output of the switch directly to the display device and use input cables that are 5 meters (16 ft) maximum. In other words, try to keep the total length of cables from the video source to the box and from the box to the monitor should not exceed 16 feet. At longer distances you may experience video degradation.
