SPX+ BEB Expansion Manual
Introduction
The BEB or (Basic Expansion Bus) units provide a simple yet cost effective way to increase the
amount of sensors and dry contacts using multiple BEB (slave units) to the single "Master" SPX+
remote unit and its single IP address.
These provide a lower cost solution for adding sensors or dry contacts and works on a short distance
only. Maximum total length from SPX+ Master to the end BEB slave is 18 meters. Therefore, we
recommend this for building up 2U, 3U type setups within the same server cabinet.
The SPX+ is shipped with a dual EXP/Modbus and BEB port module. The EXP port is like our
securityProbe Expansion, it's a long distance extension option, and therefore a more expensive
version of the expansion as you can extend up to 300 meters on each SP2+ and SPX+ unit. This
would be the E-Opto16 and E-Sensor8 that are compatible with the securityProbe and DCU series
units. The EXP/Modbus port also supports the RS-485 Modbus (see SP+ Modbus Manual).
Note: Your unit may have been shipped with the dual EXP/Modbus Ethernet or the EXP/Modbus &
separate BEB modules if it was shipped prior to us changing to the dual EXP/Modbus BEB module.
Important Note: please note that the BEB slave units are only supported on the SPX+ base units
and NOT supported on the SP2+, the securityProbe or DCU / CCU units.
Example of Adding & Maximum Sensors
You can configure an SPX+ with a total of 16 sensor ports, and then you can add the BEB expansion
units and have 16 sensor ports each. You are limited to a maximum of 150 sensors on an SPX+, that
is 150 sensor points, not physical sensors.
For an example the power meter or PMS is already counted as several sensors (voltage, current,
power factor, KVA etc) each of these data points is a "sensor" in in the SPX+ database. Another
example would be the dual temperature humidity sensors which would count as two sensors, or two
sensor points.
Also note when the VPN feature is enabled on the SPX+ the maximum sensors is 42 instead of 150.
For more detailed information on the VPN and other licensed features please check the SPX+
product manuals on our website.
