12.3.2 Power supply via PoE (Power over Ethernet) on X4 (ID ISC.MRU102-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:
•
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.
•
A connection of the PoE Port X4 to devices at outside building installation (e.g. con-
nected to the outside plants) is not allowed.
•
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.
