Understanding what data and power is on a CAT5/5 cable is becoming increasingly important as cables are becoming crowded with a wide variety of data devices and power sources. The Triplett POE-1000IL Power Panel CAT5/6 DVM is the right tool because once connected, it goes to work scanning each pin on a connector and displaying both the activity and pair location. Whether it be network devices, phones, or Power Over Ethernet, all is displayed. If you are a VOIP phone and IP camera installer, you willo find the Power Panel particularly useful because you will know there is power and a data pair available for your equipment.
