2.2 Remote Stations And Network Connection
2.2.1 Notes On Cable Lengths And Power Supply
The T24 door station can only be powered using the Ethernet port of the door camera.
A MOBOTIX PoE adapter (MX-NPA-PoE) or other similar, high-quality PoE product
conforming to IEEE 802.3af is required to supply the T24 with power (PoE switch). A PoE+
switch (IEEE 802.3at) or a 48 V power supply unit can be used to supply power to the T24
version with Mx2wire+ technology.
The maximum length of the network cable for power supply over an Ethernet cable
is 100 m.
Make sure that you only connect the door station or T24-Info2wire+ indoor unit to switches
or routers that support the 10/100 Mbps network interface. Check the LED activity of the
corresponding port at the switch or router.
2.2.2 Direct Connection Of One Remote Station
If the door station is to be connected for operation to one remote station only (computer
with MxEasy or VoIP videophone), MOBOTIX recommends using a MOBOTIX PoE adapter
(MX-NPA-PoE) to supply power to the door station. Connect the devices as shown in the
following connection diagram:

Note
The Grandstream videophone has two ETH connectors, and it can alternatively be
connected wirelessly to a network using a WLAN stick (USB port).
