T26 System Manual Part 1: System Overview
1.4.4 MX-GPS-Box
Order no.: MX-OPT-GPS1-EXT
The MX-GPS-Box primarily serves as a high-precision time
source for systems without an Internet connection. In addi-
tion, it can provide triggering based on GPS events (reach-
ing or moving away from a specied position; exceeding or
not reaching a specied speed). This interface box can be
attached to all MOBOTIX cameras with an MxBus interface.
The MX-GPS-Box is equipped with the same compact housing as the other interface boxes
(protection class IP65, –30 to 60 °C/–22 to 140 °F). This interface box should not be installed
inside of other wall mounts, but on the exterior of the building with a large section of open
sky above it. This ensures the best possible reception from GPS satellites and thereby the
highest possible accuracy of the received GPS data. The maximum length of the MxBus
wiring (0.8 mm diameter wires) is 50 m/55 yd.
1.4.5 Additional Devices for PoE Power Supply
By default, power is supplied to the DoorStation via the network cable that is connected to
the Ethernet terminal board behind the camera module. PoE injectors or switches with
integrated PoE power supply according to IEEE 802.3af can be used to supply power to
the network.
PoE+ According to IEEE 802.3at for Mx2wire+
If the T26 version with Mx2wire+ technology is installed, data and power are supplied to the
door station via a two-wire cable, which is connected to the network via an Mx2wire+ indoor
unit. Due to the increased energy requirements of the Mx2wire+ technology, PoE supply
according to IEEE 802.3af is not suicient. A PoE injector/switch (performance class PoE+
according to IEEE 802.3at) has to be used instead, or an external voltage source (48 V
DC) must be connected to one of the two Mx2wire+ units (info module or indoor unit).
