Introducing the Byte Brothers Power Panel Tone Star - Model POE1000ILT. CAT5/6 cables are jammed with data, phone, surveillance cameras and now 48 volts of PoE (Power over Ethernet)...the Power Panel Cat5/6 DVM spots these devices. And, two interactive buttons exercise both LAN switches and the Power over Ethernet (PoE) ports. Plus, the inline version allows connecting between 2 devices, passing the PoE power through to the VoIP phone or camera and measuring power (in watts). All Power Panels come with a port beacon feature and tone generator to help locate ports and wires. The POE1000ILT includes a feature-rich, filtered probe. If you are an installer of VoIP phones or IP cameras, the Power Panel will soon become your favorite tool.
