If I want to use Power Over Ethernet (instead of using the included AC adapter), which timeclocks use which POE component?
B2000: Accepts 12V POE directly via ethernet cable (e.g. from a POE network switch). Can also use POE adapter/injector.
BC100, RF200, HD300: requires POE converter (which splits the single ethernet cable's data and power into 2 cables that plug into the clock). These cannot use the POE adapter/injector.
Wx100 (1100, 2100, 3100): POE adapter/injector. Will not work with a POE network switch.
