SPX+ BEB Expansion Manual
- 5 -
The BEB will always be an RJ-12, this allows to differentiate these from the EXP connection with the
RJ-45. You can always use CAT3 cable Instead of CAT5 cable if this will be easier for your
installation.
Maximum Cable Length
The Maximum total distance between the SPX+ and the last BEB in the string of BEB slave units is
18 meters. So, for the example shown above with 1 x SPX+ and 3 x BEB slave units the maximum
run lenth of each cable is 6 meters.
Additional notes on BEB configurations
There is no maximum number of BEB slaves, in theory, the limitation is only on the distance, 18
meters from the master to the last slave device. The main limitation really is in the 150 sensor limit on
the SPX+ itself. You will most likely reach this long before you max out the number of BEB units.
There is no maximum number of IO (dry contacts) modules, the only limitation would be if you wanted
to fit them in a 1U configuration. You can only get 40 IO ports on an SPX+ BEB. If you include more it
will be longer than 1U.
We do not recommend extending BEB units to other server cabinets. As explained before, the BEB’s
are designed principally for expanding within the same cabinet only. For example, if you wanted to
build an SPX+ that is similar tp our SP8-X60, it would be a 1U device. So you can build an SPX+ and
an SPX+ BEB and connect them together with a short cable from 1U to the next. The main thing we
recommend considering is the total distance from the SPX+ to the last BEB unit, this should not be
more than 10 meters to ensure good communications and power is received on all BEB units.
Support for the AKCP Swing Handle Cabinet Locks
There are no limitations on the RFID Swing Handle Locks as the SPX+ units can handle 16, so you
can connect them to BEB units as well as the main unit. If you connect many to a BEB unit you may
need to add in an additional power supply. All BEB units are powered from the SPX+ Master, but
there is a power jack for when you are connecting many power hungry sensors including the SHL’s.
Online Configuration Tool
We have a very fully featured configuration tool on our website where you can build your custom
configured units. Please see the link below on this.
