TRENDnet's Inline PoE Tester, model TC-NTP1, is a comprehensive PoE cable tester for network professionals. This compact tool accurately tests 4PPoE, PoE+, PoE, and passive PoE technologies. The TC-NTP1 PoE cable tester works on active connections, and is designed to sit inline between the PoE source and PoE device. The PoE cable tester then displays real-time PoE information such as wattage, voltage, and amperage for that connection. Testing Modes The TC-NTP1 has three testing functions: T-mode (for testing ports on your PSE device to determine the PoE switch's or injector's PoE type, and voltage output); N-mode (for non-standard passive PoE devices); and I-mode (for PoE inline testing, displaying voltage, amperage, and wattage of the connected PD). Step Button The convenient step button on the PoE cable tester allows users to cycle through voltage, amperage, and wattage readouts. It also allows users to lock the display to a specific readout (e.g. wattage) for real-time monitoring. Compatibility The PoE cable tester is compatible with IEEE 802.3af/at/bt PoE devices up to 100W, and non-standard passive PoE devices from 11V - 60V. Ports Equipped with 1 x Gigabit port for PSE connection, and 1 x Gigabit port for PD connection Testing Modes The TC-NTP1 supports three testing functions. T-mode allows you to test your PSE device to determine the PoE switch's or injector's supported PoE standards, as well as voltage output. N-mode is used for non-standard passive PoE devices. I-mode is used for PoE inline testing, which displays the voltage, amperage, and wattage of the connected PD Toggle Switch Switch between testing modes using the convenient toggle switch located at the bottom of the PoE cable tester PoE Support PoE cable tester supports IEEE 802.3af/at/bt, and non-standard passive PoE devices Compatibility Compatible with IEEE 802.3af/at/bt PoE devices up to 100W, and non-standard passive PoE devices from 11V - 60V Blue LED Display Convenient front-panel 4-digit seven-segment LED display on the PoE cable tester cycles between voltage, wattage, and amperage readings LED Indicators LED indicators on the PoE cable tester convey PoE type (active/passive), sources, polarity, and power Step Button The convenient step button on the PoE cable tester allows users to cycle through voltage, amperage, and wattage readouts. It also allows users to lock the display to a specific readout (e.g. wattage) for real-time monitoring User-Friendly TC-NTP1 PoE cable tester provides battery-free operation, and is ready for use right out of the box; just plug-in to start testing Compact Design Small and compact design of the PoE cable tester is perfectly pocketable for on-the-go PoE testing
