1.2 Possible data rates
The data rates shown in the tables are
net data rates
, also referred to as the payload,
which are given in Mbps (1 byte = 8 bits). In contrast to the gross data rates (including the
data load for the operation of the system) that are usually provided when the performance
data of DSL connections is specified, for instance, the amount of data shown here is the
actual amount of data that is fully available to the end device operated on the Mx2wire
receiver unit. As an example, a MOBOTIX network camera only requires a data rate of
approximately 2.5 Mbps.
Notes
When long cables are used, voltage drops may make it impossible to supply end devices
with power, so a separate power supply must be provided. In other words, the data
range is generally greater than the maximum power transmission line.
Only a network patch cable with a usual maximum length of
10 meters
should be
connected directly to an Mx2wire unit in order to bridge the path to the next device
(switch, router, PC, PoE injector or IP camera, for example).
No provision is made by MOBOTIX for any further extension of the network, for example,
by connecting a longer network patch cable to Mx2wire.
It is also not possible to link more than two Mx2wire units.
PoE Power Level classes (IEEE 802.3af Standard):
class
Max. Power consumption
0
0.44 W – 12.95 W
for Mx2wire
1
0.44 W – 3.84 W
2
3.84 W – 6.49 W
for end device (max.)
3
6.49 W – 12.95 W
The tables on the next page contain sample performance data that was obtained by
MOBOTIX under real conditions and using standard benchmark test procedures.
By correctly combining
or twisting additio-
nally available wires
to form two wires or
cables, the maximum
transmission line for
data and power can be
considerably increased
Mx2wire always logs on
as a Class 0 device and
supplies end devices
with up to 7 watts of
power (up to Class 2)
