Klein Tools' VDV Commander™ Test Kit locates, tests and measures coax, data and telephone cables to ensure fast and accurate installations. Identify the distance to a short; then determine if a cable is broken or damaged. Ensure compliance and identify cable runs outside specification. Measure cable remaining in a box or on reel. Simplify cable estimating and bill jobs more accurately. In addition, the Commander detects Power over Ethernet (PoE) and can store and output test results for easy report management. Use the Link Light to identify a hub or switch with a blinking light or visually locate cable runs by flashing system status/activity LED.
