4.1.2. Power Supply via Power over Ethernet (PoE)
Optional the reader (only MRU102-PoE) can be powered via the LAN connector on X4 with the use
of a PoE „Power over Ethernet“ power supply according to IEEE802.3af*, Class2 (6,49 Watt).
The DC supply can be achieved via the free pin’s 4,5 and 7,8 (Midspan-Power). Also a “Phantom
Powering” (Inline-Power) via the signal pin’s 1,2,3,and 6 is possible.

NOTE:
The reader has to be supplied by a limited power supply (e.g. NEC Class 2/LPS power sup-
ply) according IEC EN 60950-1 chapter 2.5, only.
It must be ensured that the reader is supplied with 42,5 V DC (48 V DC – cable losses) at
least.
The maximum cable distance for Ethernet is 100m.
It is recommended to use a shielded twisted pair STP CAT5 cable.
* For detailed technical information regarding the 802.3af standard, please refer to the most
recent edition of the corresponding IEEE specification.
