PoE Tester Gen2

If I have "Simulate PoE Device" set to OFF, and I connect a PoE PSE and a PoE PD, should the PSE power up the PD? This is not happening with the unit I have.

Great question! With an active, or auto-negotiating PSE, the simulate toggle needs to be turned 'ON'. If it is 'OFF' the negotiation bewteen the PSE and the tester will not take place.

The manual states that "The display shows volts, amps, and watts for 802.3af, 802.3at, passive PoE, and DC power supplies when the tester is connected to a powered device, however the product description states bt is also supported. Does Gen2 have the capability to report of power, voltage, current and pass-thru mode testing for bt in addition to at/af?

Yes, our PoE Tester Gen2 will support the 4-pair testing capability for the new IEEE 802.3bt PoE standard which is up to 90 watts.  Our 1st Generation PoE Tester will support the IEEE 802.3af and 802.3at passive PoE.

What’s the DC input voltage for the 2.1mm plug?

The PoE Tester Gen2 will display 3.5 to 57 volts and 0 to 5 Amps on the DC.  It will display 12 to 57 volts with 0 to 1500 mA on the PoE (RJ45).

Will this support 802.3bt PSE readings up to 90 watts over 4 pair?

This PoE Tester Gen2 does support 4-pair readings to display Volts, Amps, and Watts of the new 802.3bt standard.

I'm assuming the tester runs off the POE voltage, if there's no battery, how would it handle a break in a wire? For example, how can I know "wires 1-3 good, wire 4 bad, wire 5-8 good"?

Correct, this tester is powered through PoE on the RJ45 or from a direct power supply using the DC barrel connector. This tester is designed to measure voltage, amperage, and wattage and does not diagnose line readings. If there is a break in a wire used in line, the tester will not display a reading.
