How To Test A KVM
Testing each KVM was more of a challenge than we first expected. Our normal testing methods used to test other products didn't really apply to testing these KVM units. What we came up with is the "Tom's Hardware KVM Obstacle Course." The KVM Obstacle Course is a series of ten "pass/fail" tests that we tried on each KVM unit to see how it was able to function in several real-world tests. Each test was graded using the pass/fail approach.
A "pass" means that the unit functioned correctly and no problems were encountered. A "fail" means that the unit was unable to handle the same test criteria, or the unit didn't perform correctly in that situation. Because of the differences in configuration in each KVM unit, some units could not complete certain tests. Example: The KVM100SK from Linksys does not support USB so, on tests where the unit didn't support the function because the unit does not offer that feature, we indicated that with a N/A ("Not Applicable") on our chart.
