Mx2wire+ Power Supply (Own Consumption And End Device)

It is important to consider the fact that the Mx2wire+ pair requires approx. 6 watts for its

own consumption (3 watts for each Mx2wire+ unit) when making the choice of how to

supply the Mx2wire+ pair and the end device connected to it (e.g., MOBOTIX camera).

Power can be supplied via one of the two Mx2wire+ units or via both units at the same

time (for long cable lengths).

There are two basic options here:

1. Connection via PoE device (PoE injector, PoE switch or a combination

router/PoE switch of classes 0 or 4)

2. Connection via an external power supply unit (48–57VDC, 600mA)

Connecting A PoE-Supplied End Device (e.g., MOBOTIX Camera)

It does not matter which of the two Mx2wire+ units is used to provide the PoE power supply

when connecting a PoE end device to the Mx2wire+ media converter. Always ensure,

however, that sucient PoE power is supplied. Due to Mx2wire+'s own consumption, a

maximum of 13 watts can ultimately be delivered to a PoE end device.

Less than 5 watts of power is sucient to connect and supply a modern MOBOTIX Q24M

Hemispheric Camera with all its integrated functions (long-term recording to ﬂash memory,

audio, two-way communication, recording upon detection of movements in an image,

convenient event searching, etc.) via the two-wire cable, for example.
