I have both v1 and v2. V2 has the external poe on the cable and v1 has it built in. See hdtvjeff's post above to see the box on the cable for the poe. Firmware is "NOT" interchangeable. Firmware for v1 comes out more often and v2 less often for major updates only 2-3 times slower than v1's.
They look and work virually the same. I have not seen a difference other than different ir reflectors and firmware which by now v1 is better... my opinion only
