Does this product display current?
The PoE Detector isn't used in-line with a powered device, so you cab't use it to test current. If you need this function, please use our PoE Tester.
What does a red blinking LED mean?
Red flashing indicates reverse polarity of 802.3af/802.3at.
What does a flashing green for 8-12 and then flash blue signify?
This is a very interesting reading as the detector is designed to show a solid green for passive (24volts) or solid blue for 802.3af/at passive. OR a flashing blue for active 802.3af/at. Please contact our technical support team so we can gather more information about your application. Thank you. 512-479-0317
Is there a way to tell 802.3af vs at with this device? ~Thanks!
Since 802.3af and 802.3at are both Active PoE with voltages ranges 44-57, no you cannot tell the difference between 802.3af and 802.3at with this device.
I expected this to have a consistent flash (more frequently) What causes this to flash is it the presence of voltage on certain pins?
The flashing indicates Active (Auto-negotiated) power on either mode A (1,2-,3,6+) or mode B (4,5+,7,8-).
How much current does this device draw?
This detector draws .05 watts.
What does flashing green mean?
Green flashing indicates an active negotiation.
Is this device safe for 4-pair passive POE [(1,2+),(4,5+),(3,6-),(7,8-)]? Is there any indication between 2-pair passive (mode B) and 4-pair passive (mode rA&B) [common Ubiquiti passive POE]?
This tool allows you to detect and identify IEEE 802.3af/at, 24 volt passive, and reverse polarity Mode B but not reverse polarity on Mode A. The detector should read passive 4-pair POE. It would show both mode A/B LED lights simultaneously.
