Ubisense – Ultra-wideband Location System – Ubisensor V2.0
Installation and Operation Instructions
Mounting options
Ubisensors have three mounting holes in the back of the case, to which external clamps and
brackets can be attached. Two holes are M4 size, the other hole is M6 size (and can be used in
conjunction with a standard photographic camera mount).
Setting up a sensor cell
Ubisense will have supplied you with an updated location system database containing
configuration information for the equipment you have received. At this point, it’s worth checking
that the MAC (Media Access Control) addresses of the Ubisensors you have received match the
information in the database, using the Ubisense location system configuration tools. See the
software manual for details on how to examine the contents of the configuration database – the
MAC address for each Ubisensor is printed on a label affixed to the rear of the unit (see “Features
of the Ubisensor”).
Once you are sure you have the correct equipment to hand, the sensor cells for the system can
be set up. In the Ubisense location system, a large area of space is covered by a number of
sensor cells, each of which (individually) covers a smaller area.
Each sensor cell has a master unit and number of slave units (usually three or more). The
information provided by the Ubisense location system configuration tools will let you identify, for
any particular sensor cell, which unit is the master and which are slaves, using the MAC
addresses of the devices. The master unit in each sensor cell generates a timing signal which is
used by the slave units of that cell. The master unit is connected to the slave units using shielded
Category 5e cable (or better). A timing cable from the master to a slave can be plugged into any
free timing socket on the master, but must be plugged into the top right-hand timing socket on the
slave, as shown in the diagram below.
All sensors are connected to the standard network using a Category 5 unshielded cable (or
better), and to a power supply (typically via a 12V DC adaptor such as the Stontronics EPA-
121DA-12). The final wiring interconnection diagram for a three-member sensor cell would be as
follows:
